screen corrupted / faulty

I got a serious problem with my mda vario here.
sometimes, 7 out of 10 times, when i get a call the screen gets totally corrupted and jumbled like on the picture in the attachment. i can only see black vertical lines on a white screen. in order to make the screen work properly i have to turn the phone off/on (stand-by mode) then.
does anybody know where the problem is?
i have to confess, that the phone slipped out of my hands and fell on the ground 3 times so far.
thanks

well, you say youve dropped it 3 times already? is it possible that something may be loose inside? is there cosmetic damages from dropping?

yes, there are some scratches on it. i don't really think that something is loose or broken, because the screen gets only on icoming calls corrupted.
so i don't think that it is due to a loose contact or something like that...

I have exactly the same problem. I personally think it is unlikely that dropping the phone has caused it as it corrects when you cycle the power button. Any help on this from other forum member would be much appreciated.

Any resoluation this? I have the exact same problem!!

Oh dear ... somethings in the air...
mine's got it also. first time i saw it was a couple of days ago. only happens with the alarm clock in the morning :?
My phone is crap like hell... gotta hard reset and reconfig the damn thing. acting up lately...
(ps... AFAIK i barely dropped the phone... maybe 1 or 2 times. nothing more)

I have the same problem
I have read the service manual of wizard and said:
Unusual Vertical / Horizontal lines or partial display
(1) Check the connection of LCM FPC whether is properly connected. (Is a conector between motherboard and LCD)
(2) Try with another LCM. (LCM=LCD Screen)
(3) Try with another Main Board.
(4) Replace LCM if necessary
(5) Replace Main Board if necessary.
(6) Once the defective part has been identified, verify it again with the defective part whether the
symptom could be duplicated
Any sugestion?

Okay..
so far, i have installed Molski 2.26 rom (30meg free version) and upgrade the radio rom form 2.25 to 2.47.
I have not had another occurance of this so far.
Maybe a fluke.

Screen fixes when pressure applied to bottom of the screen
Guys,
I now have to keep my finger pressed hard against the bottom of the lcd unit to get the screen to display to work properly. it is under warranty with Imate but they want me to send it to Abu Dhabi for repair. I'm in Canada and concerned that I may not get it back.
So has anybody else identified this as being a loose connection rather that a real hard fault. Also has anybody fixed their unit by dismantling and reseating the connections.
Finally has anybody used the Imate repair service and was it timely & reliable?
Any advice would be appreciated.
Mick

This is a real hard fault.. had it with my mini s, took it into the shop, it was away 2 weeks... and in the end they gave me a replacement!!

I agree - took it completely apart and cleaned everything ....
And still have the issue.
Serves me right for buying something in Middlesbrough I suppose
It must be a hard fault with the LCD assembly. Will have to see how Dixons handles an overseas repair.
Take care & thx,
Mick

I had the same problem, in the end i took it into my local t-mob shop to have it repaired, they ended up sending me a new one.

Well, I've exactly the same problem since the past two-three weeks, it also occurs only in the morning. I'm living in the Netherlands and this is happening since it's rather cold over here, especially in the morning (3-4 degree Celcius). Since my bedroom window is open during the night, it gets rather cold in my room.
During the rest of the day it is +8 degree Celcius, and the phone works flawless. Maybe this problem has something to do with the Temperature?

Temperature
Bebob - don't thin so as I have had this problem for a number of months and the temp here in the summer is high (30+ degrees C)
It looks to be a bad connection type issue and may be a bad screen cable. It makes sense though that the issue is at the bottom of the screen cos this is where we press the select buttons all of the time.
Pls keep me posted on how you do. mine is going to a local repair shop (on my dime) tomorrow to see if they can fix it.
If not can any of you guys recomend a new unit that could be considered an upgrade to the KJAM ?
Many thanks
Mick

suggestions needed
friends, i have o2 mini s and got the same problem with screen for the last 3 weeks....
can anyone tell me that will the problem aggravate or else will i be able to use my cell properly for few months...
and also what will be the approx cost of repair..
all suggestions will be warmly appreciated...

It's happened to me as well. I have lived with that for one month now. It is happening, when I touch the cursor keys or when touch the lower part of the display. I tried "shaking/hitting" the xda and it looks better, so I assume it is a faulty connection cable.

I have active Cleartype and no more vertical lines for the past 2 days.
I seems to be a problem when background is white and leters are black.
Regards

similar problem
i dropped the phone (T-Mobile MDA Vario) and now when i turn it on the screen is fine for 5-30 seconds but then it scrambles, but works again if i smack the bottom of the phone on my hand!
t-mobile staff told me there are sensors to identify if it has been dropped. I'm suspicious that it could even be programmed to go "faulty" once it is dropped as the screen is fine for a limited time so it obviously works somewhat. do you know if this is the case? or what's happened? also is it a simple thing i could do myself? i didn't take out insurance so that's why i haven't just claimed off that as i'm really broke
Any help is appreciated
Regards,
Steve

whiteish screen / over temperature
hi,
I have a problem smilar at qtek 9100. I had upgade to my ppc wm5 to wm6 around 3 week ago and overclocked to 221 mhz with batery status today plug-in . 2 days ago Screen became whiteish (almost no contrast or over gamma) and working temperature is around 30c. I tried to re-flash with many kind roms but noting chaged.
Is there anybody has these kind of experice. If I can not solve. I am planing to buy new LCD ( I am not sure new LCD will solve the problem)
Thanks

Same problem here. Dropped it ONE time and the screen went crazy. Sent it to my t-mob shop and they got it repaired. They said in the report that they changed the "flex". Dunno if this helps.

Vario II Touch Screen goes off :(

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.
Cheers
Daniel

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.
Greetings.

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.

HTC Repairs Suck!

2 weeks ago, my HD suffered a problem where it would randomly reboot. Eventually it would not power up at all. I have just received my phone back from HTC repair centre, and after 2 hours of use..... guess what ...... same problem is happening again. According to the repair sheet, the main board was replaced - but obviously not the cause of the fault. I've been without the phone for over a week now and i rely on it for work.
I was contsantly tracking the progress on line, and the repair took less than an hour, with probably 2 hours of testing.....
Anyone else had similar issues? Should i push for a new phone rather than repair, as it seems they can't even get this right.......

i dont buy that. it would be cheaper to just give you a new one. they probably noticed a faulty connection and tried to fix it.
when this sort of thing hapens, you should allways try to get a new one.

Consider keeping a backup phone for these issues: when I bought the Touch Pro I kept my Tilt, and damned glad I did.

After changing motherboard, it should be a new machine internally.
The same symptom should not occur unless it is software problem.
Did you try using it without installing extra programmes?
Did you install any special program afterwards??
If yes, you should do a trial run after each installation.

am thinking along this line too... is it a bad program?

The only app that was installed was lumos to control the backlight, however no one else has reported isues with this killing the device.
To me it sounds like the power module is at fault, causing stress on the main board. They fixed what was damaged but not the cause. Surely the device should have been power soaked before returning.

lumos is ok on mine..

The phone came back with a new IMEA number, so they did replace the main board.

pretty tricky problem imo .. fancy not fixed even with change of mainboard

Well after contacting HTC again, they want me to send the phone back - this time with the battery. Can't really see how the battery can kill the device, unless it is trying too pull to much current during charging? Surely there must be a protection circuit to gaurd against this..........
Does anyone have an email address for HTC - other than the "automated response" ones which reply with useless comments?

HD2 hardware failure?

I have noticed that my HD2 tends to freeze under load under any OS. It doesn't matter whether I'm running android from SD or NAND, or WINMO. It runs fine during most tasks but anything which increases the load such as surfing the web or playing a game will freeze it. It seems the freezing is related to overheating. Once the battery temp nears 35-37c, it will almost certainly freeze. When its even a little warm, all it takes is about 30 seconds of angry birds to freeze it, if its cold, maybe 15 minutes.
I have tried everything from task 29 to trying many roms and different radios, even the stock TMOUS rom will freeze under certain conditions. My phone is not under warranty and I don't know what else to do.
Does anyone have any advice?
What could possibly be causing this?

And your reset button is what color?

The reset button is the little one under the battery cover, but don't worry about that question - it's really not relevant and will offer no suggestion as to how to help you.
It sounds like it overheats far too easy. To me, because it happens with any OS it sounds like a hardware problem and I'd send it away for repair.

That's what I thought. Any idea on any other potential causes? I wonder which area of the hardware is faulty. Ugh, I have a feeling this will be an expensive repair, maybe its better to just get a new phone?

Most likely a hardware fault
I had similar problems. Took it back to the supplier and they replaced the motherboard.
Seems to work fine now.
I suspect (but have no proof) that the problem was caused by the stand I was using. The micro-usb connection was very tight and I had to wriggle the phone to remove it from the stand. Maybe I broke or cracked a connector on the motherboard.

Yep, that's exactly where it gets hot...
Anyone know how much HTC would charge for a repair without warranty?
Ugh, just when NAND comes around and makes this phone really nice, mine decides to die...

Was your phone getting warm while crashing?

whaaaat
my hd2 crashes when i boot winmo, it doest get hot.. it just fails..
but when i go to start very quick, that doest happen.. i flashed it.. same prob. stock rom.. same prob? when i boot android NOTHING happens.. just... nothing.. it doest even restart.. what could be the possible couse of this failure?
greetings

The reason why it is getting hot at the bottom of the screen is because that is where the whole mainboard is with the prossesor and the NAND memory chips right together almost. The processor/CPU is what gets hot and over a period of time of getting exsessivly hot it begins to break down the connection of thd CPU and the mainboard. HTC kind of screwed up and did not incorperate a very good cooling system or heat disapation system in the HD2

if you have the possibility send the phone for repairs, if you still have it in warranty. If not, HTC will charge you with the cost of a new motherboard, that should be around half the cost of the phone. Also, I strongly believe that because the nature of the problem, HTC will not attempt any type of repair on the old motherboard.
As a last resort, maybe some service centers could be able to attempt some sort of ghetto-style repairs on the old motherboard (if you are willing to try untill paying HTC for a new motherboard). As I described here, i found a solution to my problem (similar to others) and so far it's working.

I also know the problem tends to be degenerative, I'll return and post to that topic the steps it takes and how it gets even worse.

High temperature on HD2, Nand or SD?

I've got big problems with hight temperature on my HD2 with android on nand.
I can't use it outside my home because if the sun point to my HD2 it will be hot after only one call, and it stop working.
I wonder if this issue is a android on Nand problem or it's the same with SD version.
I'm living in Italy, and it's hot, but I wonder how middle est users can use it
What do you think about it?
Any idea about how I can solve it?
Thank you

i live in Egypt and having the same problem but only after a long call or using the internet on the phone...specially when using the internet the phone got a high temp and then stop working..
the only thing that came up into my mind is the radio so i thought of changing the radio version but didnt try it yet..would this help?
any ideas please?

It depends on which ROM you use i think. So far I am using SD build and didn't encounter any problem where it heat up until hang...

first - try to make sure if it dies at approx. the same temperature (e.g. using Battery Monitor Widget or anything similar)
second - search for "overheating" on xda/HD2 forums, generally two main possibilities:
1. battery pins are bent, try to straighten them delicately, and it may be ok
2a. chances are, you belong to the small majority of HD2 owners with defective mainboard (sincerely hope you're not), in which case the best solution - if available - is warranty repair
2b. if you're sure it's the mainboard and your warranty is over check here for more info
wish you luck

My HD2 blocks if the sun or if i use any application for a long time, ando long time it's like 5-10 mins...
To me this started happening after installing a new rom, and create a partition on the SD card, before that it was rare to freeze.
Can this be related to the use of the partition on the SD card?
I use a NAND rom before and now.
I've seen the battery and the pins seem to me to rights.
ps: sory my english...

Again, first start observing the temperature, if it happens at ca. the same level, you may have a mainboard problem.
Used to happen to me a lot, to the moment when to run the device for 10 minutes I needed to put it into refrigerator first, now after warranty repair it gets up to 40°C when running android from SD and works without problems.
Sent from my HTC HD2 using XDA App

I'm in Israel, i use my HD2 all day as GPS and its getting direct sun light and it getting up to 50 degrees Celsius but it wont stuck.. its reaching a point when its to worm to charge so its stop charging but also doesn't waisting battery..

I think that I'm not lucky, it seems to be a defective mainboard. I will check tomorrow if the problem will be still here after using W6.5 rom, because I don't remember this problem the last year with windows mobile.
Thank you for your kind helò
