Hello
I bought mine Vario II (with CoPilot) just 8 days ago, so I've enjoyed it quite a lot for the past days
yet .. ~30 hours ago I found out that the touch screen was not responding at all .. well restart did not help, getting the battery out and putting it back again didn't help too ... I tried to do EVERYTHING with the thing ... starting with restoring factory settings (all the data! ) , ending with browsing the forums for common failures ...
Finally I ended up with the very start page where the Vario II asks for tapping the screen (irony huh ?) to start setting it up ..
Since I was not able to make it work again (the whole thing seemed to be working fine ... just the touch screen ... ) so I brought it to the local T-Mobile shop today in the morning.. guess what, the guy at the shop just removed the battery and put it back again (I've done that XXX times during the night) AND IT STARTED WORKING again ... I couldn't understand anything there, felt really lame
anyway after I've left the shop and used it for quite a bit it started again .. now I've kind of figured it out .. when I'm using the device actively (the temp raises) and it starts at the top right corner of the screen .. the touch screen just flickers there and then after a minute or so it doesn't respond at all any more .. if I just put it away and don't use it - the screen responds again after some time ...
NOW finally the question is: has anyone had any problems with Vario II like I do? I ought to think that it is a somewhat faulty device that I've got (it hasn't been physically damaged)
PS the touch-screen gets stagnant faster with bigger programs (CoPilot, Skype, etc...) and it takes some time to get stuck with just using the phone...
btw I've put a temperature thingy in the device - it shows that the battery temp is at 42 C . Isn't that a bit too much ?
yeah and how do I figure out what version it is ? I mean the S/N that is mentioned here ( http://wiki.xda-developers.com/index.php?pagename=Hermes_Problems )
?

Yes, one of my Hermes' had the exact same problem - touch screen malfunction starting at the upper right corner when temperature rose. The usual tricks to solve the screen alignment problem (loosening the screws, removing the gasket with a stripe of a business card) didn't help at all. I returned the device and got a new one.

It's printed on the box (at least of an O2 Trion) and on the sticker underneath the battery. Just look for the S/N starting with HTC6xx... but "our" defect is not the normal SA problem, it seems to be much rarer and not described in the Wiki.

Thank you so much for the answer Daniel, I'll get them to change it tomorrow.
I have exactly the same problem with my TyTN. In the morning, after the phone has been off all night, the touchscreen works for maybe 30mins, then the phone warms up and the screen ceases functioning. Bizarre though - I got the phone about two weeks ago - the screen worked fine (i.e. under all temp. conditions) for about 7 days, then it decided to crap out. Tried all the usual SA type solutions - as you guys noted above they didn't work. Gonna have to go back to the shop and get it replaced :-(
Oh, nearly forgot, s/n is HT632
One other thing I noticed (not sure if this is normal behavior or if it started after the touchscreen borked) - When the phone is active (i.e. not locked or in standby,) the top status leds (wifi, bluetooth, gsm) don't flash. Once the device is put in standby (i.e. tapping the power button) they start flashing again. Like I said, not sure if this is normal or if its related to the touchscreen going.

This is definitely not normal. But it's an interesting observation. If the TyTN were a car, I'd say there's a bad ground connection somewhere.
Try a hard reset, and if that doesn't solve the problem, have it exchanged. (I very much doubt that a hard reset will help, but at least here customer service refuses to exchange a device before you tried a hard reset. )
Cheers
Daniel
Hard reset borked even more. Could't get past the touch screen calibration. Phone is now in the freezer to cool down - hopefully the touch screen will work long enough so I can get past the calibration
*EDIT* Just got it out the freezer (nice and cold now.) Hard reset, got through the calibration, everything ok for about 10 mins. LED's flashing with backlight on and touchscreen working. Then - touchscreen non-responsive at exactly the same time the status LED's cut out. I'm hypothesising that there's some kind of electrical short between the circuitry for the touchpad and the status LED's - it shorts as the devices temperature rises and (i guess) some of the materials expand and come into contact with each other. Since I don't want to void my warranty in case I have to take the phone back to the store, I haven't opened it up to confirm this. Has anyone had a detailed look at the connections at the top of the screen and around the status LED's to see if my explanation is at least possible? (then I might open it up and see if I can insulate the connections.)

I have the exact same problem!!
Two additional points :
1) my device screen will not switch off automaticaly and will stay on for ever unless I switch it off
2) When the issue manifests itself for the first time the device would automaticaly go back to the today screen like if the OK button would have been pressed many time or ... was stuck!!
That's my second Tytn device the first one had the SA defect.
I was so happy when I got my new one because the S/N showed HTC637XXX but sounds like a new issue even though I'm pretty convince that that the SA issue is not far from being related to this one.
My device SPV3100 HERM100
Hello lads,
Absolutely everything you've posted seems to be happening to my device.
Now the touch screen fails to respond even if it's cold (been lying on the bed for 5 hours doing nothing at all .. ). damn... seems like I'll have to ask the local shop to get me a free portable refrigerator for the thing to work properly

Might get a chance to have an internal look tomorrow. From memory, and can't remember if the Wiki or Japanese dismantling site shows this, but I recall only a single mylar ribbon cable coming from screen area through to main board. There are if memory serves push in multi connectors from the bottom hard keypad and from front camera board (inc LEDs) to the muti ribbon cable on the back of the screen. Thus, simply put the screen, camera,hard phone keys all connect at the back of the screen to a single multi ribbon cable that goes to main board. Possibility then of a short with digitizer is at least possible. Of course digitizers are suceptible to current leakage and field interference so would not have to be an actual physical contact but could just be a close proximity issue.
Mike
Facing the same problems...
... I've been thinking about repalcing the display and the touchscreen. But now, considering that it is a HW issue, I can only replace these two things. If the bug is in the module above the screen (statur leds and camera) or related to the wireing at the back of the screen, it won't get rid of the problem. On the other hand, if it is a problem with the screen getting too hot, then I'm on the right track...
Has anyone tried this yet?
I'll try to call HTC on monday, maybe they know where the bug is.
HTC is not able or not willing to share what they know about the problem...
Hello, they excuse my English, I am possessor of a TYNT and I am with he himself problem that you, the problem is a failure of weld in the processador, when it reaches certain temperature fails and cooling it or pressing strongly on the processor it lets fail.

There may well be truth in what you say, I too believe it is something similar in some cases.
Do you have any proof of your suggestion. Can you provide pics or a diagram of the solder point you mean??
Mike
Hmm? The processor...?
...sorry, don't think so.
It's just that this bug occurs after using a device for months, isn't it?
Now, the first two weeks I installed all kind of programs using the wireless LAN almost permanently. My Hermes was never as "hot" as during its first two weeks. And what about the sliding-out of the keyboard? Doesn’t it always start there? This just doesn't sound right, does it?
Just received an email from someone who drew my attention to the ribbon cable connecting the upper and the lower part. What if there is a short one due to the plastic scratching the cable and then... who knows?
However, I do not disagree as far as the temp is concerned. Therefore, I'll put my Hermes on ice and see how long it does things right...
And still, there is no chance that it is related to the processor. If the processors ALU is getting too hot the entire device would be effected, wouldn’t it?
Anyways, I'm determined to find out what it is!
++ I just found a very peculiar post in the WIZARD forum. It was about some top-side buttons that kept pressing
++ without even touching… Opening the assigned programs over and over again. Odd, isn’t it?
++ That’s a HTC device AND has a sliding keyboard with a ribbon cable as a connector…
++ Yet, it operates with a different processor on a different main board.
++
++ Still blaming the processor?

And you are right too! if it appears that I am tending to agree with both above posts when on the face of it they disagree with each other it's because:
1
There are different manifestations of this problem - the causes may not always be the same
2
I agree it's NOT the processor and firmly believe it's hardware related. Of course it could be be a break (sometimes intermittent) in contact somewhere between screen and board or even a broken contact on the board (IN SOME CASES)
3
In other cases it's just pressure being put on the touch sensitive screen often at the very inconvenient top right corner that closes/minimises applications or opens start menu.
There has not been a reliable way to fix this issue other than device replacement. Replacing the screen has been notable for it's failure to resolve the issue.

So do you think the bug is to be found on the main board at all?
I'm planning to replace some parts from the screen half. In fact there are just 3 possible error sources:
1) The lcd in combination with the digitalizer;
2) The ribbon cable connecting screen parts and keypad at bottom; and
3) The keypad at the bottom itself
The ribbon cable includs the electronics for the status leds as well as the EARphone. ;-)
Soon I will be on all three of the above parts and if the error ain't there... I'm going to be MAD.
Will keep you IN THE LOOP!
Hello again, my conclusion is based on which I have disassembled my TYNT completely and I have connected it without the keyboard, of this form I have hoped to that it began to fail, later I have been moving and touching in any case the flat cable that unites the motherboard with the screen, the small circuit that takes built-in without obtaining results, single I have even obtained that it returns to work blowing air on the strongly pressed processor or on. Another observation is that if just ignited the machine and working correctly we applied single heat on the processor, begins to fail the touch screen. To my also is to me strange east failure since the temperature of the processor is not excessive when it fails, in fact desire firmly to be mistaken because there am lost the guarantee. Seguire investigating is matendre informed to you.

May be a fault there, but if it's just a squeeze due to heat ? pressure it may not resolve the issue.

Again I have tested, with the disassembled machine totally, start up it, I hope to that the touch screen does not respond and I put my tynt in the refrigerator, after two minutes and without moving I touch it the screen and magic, works correctly hata that again coje the room temperature.

This is very interesting. When I said above it is not the processor, I meant it is not a software issue related to the processor. It can of course be a heat related problem with the processor. To summarise what you have found:
1
You have a device that when first started works OK
2
If you apply heat (but not much) to the processor it fails
3
If you apply pressure to the processor it works again
4
It begins working again when you blow on the processor or put it in the fridge.
5
If you move/press or ensure the ribbon cable has a firm contact - this has no effect.
Please post if any of the above is NOT correct ALSO please post which chip you are heating/pressing.
Cheers
Mike
Hello again, everything is correct except point 3 really when this failing and you press on the then microprocessor the touch screen works correctly. Associate images.
Greetings.
EDIT by Mike. Point 3 has been edited in Mike's post to show the correct situation.
Ok so I have the fabled white screen issue on an 8525. When it first occurred I searched and read all the write ups, decided I had the ribbon cable issue. Took it apart and simply unplugged and replugged the ribbon cable with great results, no more white screen.
I repeated once when it came back after being bumped around, again with positive results...but this last(3rd)time instead of it working I now get white screen 95% of the time. I re-notched the sliders the first time, and last time.
During the 5% it works I noticed the charge light would correspond to it going white.This never happened before...
Example:
When OFF - Connect charger, Red light for 1 second, then nothing=White screen from power on
When OFF - Connect charger, Red light for 1 second, then orange charge indicator = normal startup
When ON and Working - Connect charger, no light, no charge - reboots to white screen
When ON and Working - Connect charger, orange charge indicator, reboots normally.
There is no heat or noticeable pressure on any parts, everything seems to fit normally.
It does boot normally with screen white.
Any ideas? I really don't want to give up on this thing, is there any hope? or just ebay it for parts?
Thanks
-Nick
same problems here, if someone could just tell me what parts to order, cause I have no warranty (ordered over ebay). I tried both the instruction that has chinese fonts on the page , and other from R&R, no luck, white screen all the way..
I had the WSOD and took it apart and reassembled a few time. The 3rd or 4th time the screem came back, but now it is shifter to the right around 1/4" or so. I mean there is just white along the left edge, then the normal screen/color starts and is cut off on the right.
Does anyone know how to correct that, is it related to the same flex cable or is there something else I disturbed?
mine will fade to white.. then i just push the power to put it in standby, then push power again to wake it back up and back to normal.. it rarely does it but still annoying...
If You Ordered From At&t
I had this problem about 2 weeks ago!!!!
I thought it was a fluke!
Anyway, walked over to 43rd and Lexington (NYC FOR THOSE WHO DON'T KNOW THAT MANHATTAN IS THE CENTER OF THE WORLD)
and they gave me the EXCHANGE HOTLINE for at&t.
I called them up, told them my screen is fading to WHITE and the lady sent me a new or referbished phone.. i dont even know.
Just so you know, i ordered my phone on AMAZON with a new activation. its covered under the MANUFACTURERS warentee for a full year from the date of purchase... so is the REPLACEMENT PHONE... but not from the date of replacement, just the date of purchase.
did anyone get deeper into this yet? I got a 8500 (need those without camera) from ebay USA, already with white screen. After reading here, that this is mostly an issue with connectors, I bought it, disassembled it and reassembled it, though still white. Should I give the contacts a treatment with contact-spray? (there's a tuner spray that doesn't leave residues) Or is there something broken within the ribbon cables? Seller said it has been dropped (but he also said, he didn't want to open it, while it clearly has been opened, one screw missing and warranty seal gone). It ssems to boot up normal otherwise, I hear a sound after the boot process, so probably this isn't a software issue?
Edit: another thing I noticed: When I run it without any keyboard connected at all, it's also white. I then connected the dpad again, and I could see a hint of the at&t logo in the lower part of the screen. When I pressed around on the back of the dpad a bit, all LEDs would go on/off... Sound to me like the dpad has gone bad, possible?
Edit II: Got it. Using a 20x eyeloupe I found that the PCB of the DPad is broken under the little chip on it. Now I just gotta find a dpad here in germany, but I assume those Hermes' are all equal...
hello
where can I get manual (if there is one) for disassembling hermes. link in wiki does not work.
thanks
this worked good for me
http://inuchanbt.blog54.fc2.com/blog-entry-100.html
Anyone know if this applies to the 8125 as well? I've got a flickering white screen. I had dropped my phone a few weeks back and cracked the LCD. Replaced it with an OEM LCD - it worked fine for about 2 weeks and then just suddenly went all white. Phone still works, I can still get calls - just can't see who is calling.
I don't recall that the wizard had the same problem... Though from a logical point, it seems that there is an issue behind white screens and the thumbpad being responsible for it, so it may well be the same thing. Perhaps just disassemble the wizard (there should be a howto too) and check if theres a similar connection from mainboard to thumbpad circuit.
Is there a disassembling manual for a imate k-jam that anyone knows about?
Here's a website with a video manual i found useful...
http://viralelectronics.com/category/howto/page/2/
Figured out the problem...
The only reason I figured out the screen goes blank is because the motherboard loses connection with the screen when you slide the keyboard out...try this out and see if the screen comes back...
put the screen on sleep mode (no white screen)...then slide out the keyboard and tilt it a little hard after pressing on the screen and put the power on. if it doesnt work try again it might take some pressure and power to make it work...be careful not to put too much power but as far as I went, it's a very sturdy cell.
alternately, slide out the keyboard in sleep mode, and press all the buttons really hard and then try to press the power button (press more towards the space bar because that helps)...if any of this works and the screen comes back on even just for a second...follow the following
Go back to the person who gave the link to the site with opening the HTC instructions and follow through and clean the whole phone up from dirt around the screen and such...you dont need to put those rubber things or whatever it says to put on the screen...then when you are putting it back together, press hard on the wire connecting the touch screen to the motherboard. I suggest sealing it with a good tape...and then you are good to go! I did it but it had a few glitches...the screens contrast sometimes goes awry but it is still visible and responds to touch. Also, the physical buttons work as well!!
Good Luck and do it at your on risk.
Have any of you tried this? http://forum.xda-developers.com/showthread.php?t=321163

i still have this problem.
fixed my wsod
I noticed a few days ago my 8525 screen went white, rebooted and it went away. Today it came back, but would only go away for a few seconds and then back to white. After reading some forums I decided to check the connector. I took the phone apart following this site as a guide. I removed the connector on the board side and cleaned the contacts with a qtip and denatured alcohol. Phone has been perfect for the last few hours, no more white screen of death. I didn't mess with the connector on the LCD side, just the board side. I'm a computer tech and I found it quite annoying to disassemble, but I managed without causing any damage, however, I'd rate the job at about a 8/10 as far as technical ability.

i agree that this is one of the first things to try in curing the white screen issue. Others may find their problem runs a little deeper and the contacts on the d/pad chip are broken. An improvised cure which may not be very permanent is to place a little padding on the surface of the chip as described here:
http://forum.xda-developers.com/showthread.php?t=321163
If you have appropriate heat gun equipment you can re-flow the solder on the d/pad daughter board - but remember to remove the sticky key pad layer or you'll cook it!!
I regret that I'm closing this thread because we have several "White Screen" threads and the questions and answers are being spread all over the place.
Please use this one for future posts:

I have read many threads and forums about the problem of the Hermes becoming white. The soft reset in this case does not help.
I found the explanation in my case and I am not able to fix it quickly, without opening the device to screw the connector.
The problem is only due to the temperature of the device. When the temp is to hot, the screen is white, in my case, it typically happens when it stays in my pocket et I moving too much throug the office ;-)
Solution, simply open the keyboard and gently blow in the thin area between the two parts of the device.. in my case, the screen comes back in 2-3 seconds.
Enjoy !

To be honest, I have this problem on my 838 (wizard) previously.
I have found someone (engineer who I need to pay) help me to check.
It is actually the connection cable between the keyboard and screen start breaking.
This makes the connection poor.
End up, my wizard cannot be repaired and I have borrow my freinds hermes to use in the mean time.
I suggest you pay special attention to it.
I suppecm that you blow it is actually helping the connection of that cable.
huh
are you guys serious in what you're talking about?
blow in between the two parts of the device when it's hot to get the connection of the cable back?
are you sure you are talking about a mobile phone and not about a compressor?
thanks for your feedback. I am convince that in my case, the gentle blow does not move the connecting cable.
Additionaly, the tipical symptom reported in various thread is that the soft reset does not help, while letting it apart for 15 minutes does help. It can confirm that the simple temperature idea is fine.
Again, it works for me, it can help others, and sorry for the others that won't find a solution with mine!
actually, i am neutal to this topic.
But just want to share my experience.
In my case, my cable is aging. Initially, it can help with slide the keyboard open and close.
End up the engineer told me that cannot be repaired deal to no parts. he examined it using a microsope watching the cable.
no need to take it too series.
It is a cable connection issue, it is caused by either dropping or opening and closing the device numerous times. It can be fixed the part cost around $20 kinda hard to find but can be found if you search enought. I can repair the device if your interested either pm me or you can contact me at

when this happened to my hermes last August i found slightly unscrewing the two screws on the back of the screen fixed it & not had a problem since
didnt know what the white screen was 'till i got it right after the external volume crapped out, so tired of tinkering with hermes, going Kaiser
As a science experiment I have bought a number of hermes on ebay- it is a cable connection issue or worn cable in the 4 I have played with - all fixed by cleaning and reinstalling cable/connection or replacing the cable assembly. I cant say this is the only bug but 4 outy of 4 inducates a trend to me

Oh my gosh, topic starter, that is the same exact issue that I frequently have with my 8525. I eventually found out that if I leave it in direct sunlight, put it in my pocket for too long, or in anyway expose it to relative heat, then it would turn white.
That's a nice "fix" you have there hahah. As for me, I just let it cool down by placing it in a cool and shaded place, works like a charm after a few minutes.
Anyone with a WHITE screen MUST READ this!!!
To bring credit to what I say below, I haved had tinkering experience with electronics for the past 10 years, not to mention that I am currently a 3rd year electronics engineering student.
I currently have 4 hermes units.
When I first had the white screen prolem on my first hermes about a year ago (may be 8-10 months?) my research on the net revealed that the problem is apparently the connector on the button pad board (part number 50H000380-30M-A). After serious tinkering and tweaking I finally got the (extremely sensitive) connector connected up so that the white screen issue actually dissapeared. However, since the connection was so delicate and so sensitive, I had to fix it in place with a hot glue. Hot glue actually added some thickness to it; given that there isn't much tolerance between the top of the connector and the cover, I needed to scrape away some plastic without putting a hole in it so it can accommodate the extra thickness, this is also required for the sliding function to be smooth.
However, right now I have 4 hermes, and I am faced with the same issue. On two units I have the white screen problem. After some intuitive testing I have found that the problem is not with the flex cable, nor with the connector on the flex cable, nor the connector on the button pad board. The problem is with the actual button pad board itself, as it contains fair bit of circuitry on board.
This is how I came to the conclusion. Since the white screen can be fixed with sensitive alignment of the connecor on the board, I wondered if it will display anything with that D-pad (button pad board) disconnected. On trial, it didn't display anything on both a functional unit and a unit with a white screen issue. From this I made the assumtion that the LCD initialisation sequence is contained on the button pad board (part number 50H000380-30M-A).
Having made this assumption, I thought since the symptoms of having it disconnected on a functional unit is the same with a unit that has the white screen symptom, I wondered if it will fix the white screen problem if I changed over the button pad board. On trial, I found that the white screen problem was a thing of the past. So, I don't know what on the button pad board actually causes the white screen, but it is DEFINITELY the board it self and not the connector.
PS: I don't know the proper names of the components but by the button pad board I am talking about is the board that lies under the front buttons of the unit that has the call, end call, start, ok...etc buttons.
uengin, u totally had make ur homework regarding the white-screen-issue.
Anyway, for me, I face the exact problem too. And my way is much simpler. When ever I face the white-screen problem (this cause by the high temperature, coz I notice it only happen when I put my 838 on my pocket while walking during sunny day), I simply turn off the screen for a while (by lightly pressing the power button), like 3-5 second, then turn on the screen back. And, voila~ it back to normal.
i get a white screen when i press on the plastic casing on the lower right side of the screen, above the right bar button. no temperature involved here. sending the hermes to sleep and waking it up restores the normal screen.

There's actually a BGA chip in that vicinity on the button pad circuit board. It may or may not be that chip thats causing the issues, but I find it higly likely it is...

if it is the chip, then this would be a loose soldering point?
would you recommend to handle the hermes with great care? eg. not putting it in my trouser pocket because oft the pressure?

I doubt its a "loose" solder joint. It could be a dry joint. But then again you never know. However, the symptoms with the heating and cooling mentioned in the thread it could be one of the several devices on the button pad board failing due to heat.
As a general rule of thumb, definitely electronic devices of this calibre should be dealt with a level of care indeed.

Same for me which seems software issue but how to solve it
I'm having white screen problem too. I highly doubt it has anything to do with a cable because:
1) I almost never use keyboard, aka don't slide open the phone
2) lately white screen often happens when I touch a screen.
3) several times white screen got fixed by holding the phone next to aircondition outlet.
4) white screen recently started at the same time I've noticed that the battery started dying, it doesn't last as long as before. Before this battery I had another one, similar, and also never had white screen while that battery was new.
To conclude all this, at least in my case is more likely it's a battery issue and/or overheat. Tomorrow I'll use the original battery (I've replaced it with 3k mAh 2 years ago) this should proof me right or wrong.
My white screen issues started after a waist-high drop onto concrete, accompanied by the D-Pad and the surrounding buttons not working. In order to get the white screen to go away and the buttons to work again, I have a simple 2-step process:
Put the Hermes to sleep
Press hard right above the D-Pad/below the screen
When I wake the device up, it works just fine!
Interesting Find......
I just noticed something about my white screens.
IF the poweron led does NOT turn on then I get white screen when turning on my hermes.
If the poweron led turns ON(lights up) when turning my phone on then it won't white screen on me.
hay from today morning my htc touch shows a white screen and a crack on the bottom corner of the screen.i am sure that it dint fell down.
then what may be the problem?
anyone knows pls tell me...
white screen?
When you turn on your phone, there is no smart mobility.
Crack?
Is that an LCD problem?
i have the same problem with the WHITE SCREEN. bought my ELF 3450 second hand over the net. i am from the Philippines by the way and HTC units are not yet very common here and also the parts/accessories. it worked fine for about 3 months with minor problems such as Auto-Restart/Auto Power On/OFf which was solved using the "plastic on the OMAP chip method" - tnx for the forum for the info by the way and charging problems which was also solved by buying me a aftermarket charger. but recently the problem of AUTO OFF occurred again until it did not work at all. so, i tried to check the Plastic over my chip but to no avail the fone was dead. so, i decided to head to one of our local cellphone repair shops and have my OMAP heated thinking that maybe there are just contact points inside who became loose. when we tried to power on it was good for a few minutes then i noticed the screen went darker and darker and then it was all WHITE. we restarted it but it's just WHITE. tried to send messages and call it but there is no response from the fone. i'm afraid i toast it bad or may be it's just the LCD who got toasted, i am clueless.
CAN SOMEBODY PLEASE HELP ME WITHMY PROBLEM. CAN I GIVE LIFE BACK TO MY ELF? WHAT'S THE CHEAPEST & BEST SOLUTION TO THIS? THANX ...
Generally white screen problem are caused by defects in flex connecting the LCD to the mainboard or the connector itself. Try to disconnect and reconnect the LCD, if doesn't work - replace the LCD.

You warmed the OMAP? Interesting....
This problem sounds really complicated.
And im quite surprised of your 'warming' method.
I've had the exact same problem combined with the fact that my touch was resetting constantly. I was about a minute away from throwing it out of the window when I tried the plastic-piece-on-omap processor-technique described in one of the threads here. It solved the rebooting problem, but not the white screen issue. After a very frustrating couple of days where the screen started to blink and shake and then eventually turned to white alltogether, I lowered my brightness to the second stop from start, and since then I haven't experienced the white screen anymore. I believe it is heatrelated.
Whilst not being a full solution to the problem, at least it renders the phone usable.
Hope this helps anyone.
Heating the device very seldomly solves anything, but causes more problems that you originally started with.
iam using htc touch (p 3450) for nearly 18 months . (bought & using it in india ) my hand set fell two times in water and about 15 times fell on the floor (from shirt pocket) . still its working fine .
and iam using "opera mini " for browsing the internet . for some sites iam using "opera mobile " . when iam on opera mini , continueously for long ours , suddenly it turns white . never come to normal screen unless restarted . but it happens sometimes , may be because of memory or heating up of some H/W .
Hi hotchamo,
my htc touch elf hat a similary issue, and my father just "wringed" it gently until the white screen disappeared. You should try it carefully, since it may help and it won't harm. Just take in in both hands and turn them in the opposite direction, so that the case gets slightly twisted.
If that doesn't help you should open it and check the LCD flat cable connector...
Best regards,
scheutak
Again - flex connector problem. 'Wringing' it gently will eventually result in your LCD cracking, by all means - go for it, it will solve your white screen problem. Permanently.
After 4 months of flawless work, the lower part of the screen (a strip several millimeters from the edge) suddenly stopped responding properly!
E.g., all buttons in this area (including launcher/phone/+ on home screen) either don't work at all, or sometimes activate after a while when strongly pressed with the thumb (orientation doesn't matter).
Just two hours before they responded fine to the index finger.
Also, I've noticed that when I "multi-touch" the lower line in a file browser with two fingers, it works nice! Buttons are too small for that, however
I first tried to restore backup, but it didn't help, of course.
Has anybody had the same problem?? I guess it's a warranty case ...
I would agree, it's probably a hardware problem that you'll have to bring your phone in for service to get fixed.
I'm having that same problem my self, but just now and then. What helped with me is that I press the upper left corner of the phone with my other hand and then the lower part works fine, so i think i should get a new digitizer or its just loose connector.
im having the same problem , i have put up with it for the past few weeks and its driving me nuts now. today i did a factory reset which made no difference , i called htc who didnt sound a bit suprised by my phone call it gets picked up tomorrow morning to go for repair so the question is ... is this a common fault? and how the hell am i gonna cope without my hero in my pocket ?
Yeah happened to mine last week, a few have had the same issue where it's just the launcher bit not responding. Although the good news is that I'm getting it back tomorrow though so it's good times!
I had the same problem with my touchscreen (after a month or so!)
Mine got picked up thursday by HTC and I just checked the tracking site and they just recieved it.
I wonder how long it's going to take
Visited their service center last week.
They've immediately replaced my screen with a new one without any ado. Now everything works as before!
BUT a friend of mine who bought his Hero in January is having similar problems now...
It is a common problem according to HTC.
Mine was repaired in just 10 days.
Same problem here, did htc said anything about this problem? is it a common fault?
thank you
I said it in the post above yours.
ah yes, right, thank you

If they acknowledge it officially, couldn't you provide a link please?
i gave mine last week to repair, they returned to me unfixed. on the paper stated that they only updated the software, what a dumb this htc guys. need to go back and tell them again the same story. im wasting my time only for this. wtf
I recently had this problem. The 3 buttons at the bottom of the screen wouldn't respond, took it into T-Mobile who said I'd have it back within about 7 to 10 days... 3 weeks later I got a text saying I could collect my phone...
On the paper sheet it says they've replaced the lens.. Which I can see they have as before I had a miniscule hairline scratch near the top.
They also mention a software update (1.0.0.A6288)
Either way it works nicely now.
I've recently experienced the same issue - the lower part of the screen, the one where the LauncherPro icons usually are stopped responding to touch. If I press really hard it works sometimes, but it's pretty annoying. I didn't sit on the phone or drop it recently, it just stopped working all of a sudden.
Is there anything I can do, as the phone is out of warranty ?
HTC South Africa gave me a new hero after I took mine in for the 3rd time. Hardware problem. Very happy with their service.
i have this exact same problem, is the only solution to send to htc? >_> Cuz my warranty's out already unfortunately... i flashed my hero to CyanogenMod 7 and it seems to have helped, but still not completely responsive... I also have a problem where at times i completely lose control of my touch screen where the spots i touch seem to respond to opposite sides of the screen... anyone else?
Remove battery, Remove sim card. put a dryer on the htc logo for about 40 mins. put the phone under a heavy object. Let it dry for about 15 mins and your fixed.
^ wtf do u mean?... are u just being a gimp...
