Screen Alignment Experiment Mystery - 8525, TyTN, MDA Vario II, JasJam General

Try this:
1. Wait till the screen misaligns
2. Switch off device
3. Use a clean cloth and apply pressure EVENLY on the WHOLE of the screen (as if 'ironing' the screen)
4. Power on the device
My XDA Trion (HT626) re-aligns itself WITHOUT having to go through the screen alignment 'routine'.
How about yours?

And how long you have to re-do again ? Or only one time for yours then no more misalignment?

Re
I don't know, here are my thoughts.
I am 99% sure that screen pressure will affect alignment - when I had misalignment, i used the stylus to press the screen in different areas, the contact point position will change in response to this, though i have no idea where it will change to.
So even if my method does have some effect, eventually the screen layer will 'loosen' again and you will have to 'press it back'.
The 'loosening' of the screen layer may be due to vibration, heat (from battery?), deficient screen etc.

a question a bit OT: how much time after the first start your TyTN had the mis-alignment of the screen? you found it also in the very first days of use?

whassup people
had the same problem..got the tynt yesterday..today have scrreen alignment issues..tried what u told me n works..
hopefully it will keep working
thanks

works for me too
I have had an m3100 for a month now and no screen problems until last week. getting more and more frequent now. 4 or 5 times a day at the moment.
sometimes just opening the keyboard and closing it again sorts it. sometimes just pushing the screen gently here or there sorts it. if I power off and run my finger around the perimeter of the screen that always sorts it out!
I have a screen protector fitted. is this a factor?
I think it maybe due to pressure on the casing when its in my pocket sending the screen out. I've never used the magnetic case and I've not tried the screw adjustment thing yet.
my problem is, is that i've flashed the rom so I not going to be able to send this back easily for exchange even though I have orange care.

a most probable hardware issue, i have my lcd replaced and everything went pretty okay

I think.... HTC produces device while they're drunk... How was it possible? I'm a developer and after I finished to develop a software "I MUST" test it because if something doesn't work my boss become a T-Rex, and "I WANT" test it because in my opinion custom satisfaction is much more important then moneies.
Sorry for my poor english, I'm lerning it.
I am a disappointed XDA Trion owner.

Anyone with this problem try this out:
Open up the keyboard and flip the device over so you are looking at the back.
You will see two screws at the top of the screen on the rear. Losen them off a bit and retighten, but so that they are NOT AS TIGHT as they originall were.
See how you go.
I saw this mentioned here...apparently it can fix the problem for good. The issue is that the screws were overtightened at the factory and there is also a seal that runs out the edge of the screen. As the device gets used/warm the seal expands a bit causing pressure to be applied. If the screws are over tight then this impacts on the touchscreen causing the misalignment.
Try it...might fix it...

Screen Re-Alignment every day?

It seems that as of late I have to re-align my screen almost on a daily basis. It will be ok vertically, but horizontally it seems that it's always shifting.
Has anyone else ran into this?
Yep, I've run into it. Sometimes it can go days without having to realign it, other times I have to realign it every 15 minutes. Seriously. I thought it might have something to do with opening and closing the keyboard but it's been hit and miss so far. I can't prove that it and I can't prove that it isn't. Sure would be nice to figure out what it is, however, and have it fixed.
How do you carry your phone around? Do you keep it in a case on a belt clip or do you keep it in a front pocket of your pants? If you do not use a case then try it for a few days and see if this helps with the alignment problem. (Body heat and/or pressure on the screen may cause the alignment to drift.)
This is a know hardware defect. It should be covered by your warrenty. T-Mobile exchanged mine with no problem.
Mine had the same issue but it hasnt been an issue since the 2.26 update on Tmo.
I had my phone replaced and it's still having the alignment issue. This sucks bad. Realigning and resets doesn't help!

Getting rid of magic button and vbar, if you run those apps, did the trick for me...I switched to wisbar desktop and ever since I have not had to realign my screen once in 2 months
I'm going to try this out and let everyone know. I'm having the terrible screen alignment problems (I at first thought that it was the keyboard and switching landscape mode) but I have magic button installed. Going to try the switch to wisbar lite and see if that helps. Does anyone know if the business card trick for the hermes will help with this?
I think it is a hardware defect, i have problems with mine, not only i have to re-align it often, my screen is also not responding to touch either. (from time to time).
Not to respond right away without extensive testing, but I did just put on wisbar lite and noticed a definite improvement in aligment (certainly seemed better than magic button) someone else should try this too and see if they notice an improvement.
I was having this issue for awhile. The card trick had helped on my previous 8125 but not this time. Carrying it in the case instead of my pocket seems to help quite a bit. The issue also seemed to be affected by pushing on the plastics around the screen so that might be a clue right there too.
align
delete
Sounds similar to my fix of pushing on the plastics all the way around. I haven't really had this problem since I did so and I have only had to realign it a couple of times in the last few weeks.
my phone's alignment used to get screwed up multiple times a day.
I took the stupid stick on screen protector off it though and haven't had that problem nearly as often. I maybe realign once a week, and when I do, it's only because it's off just a bit.
I had alignment problems frequently a few months ago but it is all history now.
1) Fix current alignment problem.
Just make sure you confirm if it is a hardware defect first, by checking the tiny gaps between the touchscreen and the casing for dust particles. Use a high power scope(I work in a semicon backend company so no problems getting one). Clean the gaps all around the touchscreen. See if that fixes your alignment problem. If it does, then probably your screen has some electronic problems(claim warranty).
2) Protect your screen from pressure at ALL times except when you use it with your stylus or finger.
I carry my Wizard in my pocket with a plastic transparent plate covering the entrie screen(ala HP's RW6828 forgot that model already).. Have been doing this since last year and no alignment required since last year...
Just wonder why HTC doesn't make it an option of have the protective screen on their devices... Beats having a bulky casing..
Permanent fix for Alignment problem in 10 seconds
Well I read many posts and finally came to the conclusion that the best and permanent fix for the alignment problem is as under.
Slide out the keyboard, you will find 2 screws at the back. Loosen them and then retighten them but not as hard as they originally were but lightly.
Presto
Problem solved.
U will never see your screen misalign again.
Thanks
software problem
The original Cingular wm5 rom had this alignment problem, I flashed NBD's WM6 v5.1 rom and it was fixed. I tried other wm6 roms with mixed results, some would get misaligned, others alignment stays perfect. Anyway the NBD rom just works, improves battery life, speed, I could go on all day.

Hermes broken? Clicks upper right corner constantly!

I've had my 8525 for about 3 months, and now it constantly clicks the upper right hand corner and exits all of my programs! I'll soft-reset and sometimes it wont boot up, it just hangs at the windows logo screen. I upgraded the ROM to the newest from Cingular thinking it was some program that was doing it, but it comes back.
When it's in portrait mode, it's the upper right hand corner. When it's in landscape, it clicks the start button(upper left) so I dont think its a program thats making it click, but something physical touching that certain spot. Anyone have any idea?! I thought something was stuck in there but it's clean.. this is so annoying, I cant even make a call since it clicks exit when it comes up! It stops SOMETIMES for a few minutes but then it comes back after a while.. anyone else?
Give it a yung choo kung foo whack, take a run-up.
...
Sounds knackered, you could try the screen alignment fix, pressure from the gasket may be causing this:
http://wiki.xda-developers.com/index.php?pagename=How to fix the Screen Aligment issue
Your best bet is to send it back for repair though .
I bought it off ebay.. so no warranty
It's weird because I take a very slim credit card( 1/2 the thickness as regular cards) and slide it in and bring up the plastic around the screen and it STILL does it!! nothing is touching the screen at all. Also, my alignment is still spot on perfect.. what gives?
Oh yeah, I did smack it a few times and it works sometimes.. It's been okay right now for about an hour but I know it's going to be short lived..
Did you try loosening the screws?

Yours is the third or forth report of that error. My Trion had the exact same problem, and I needed to exchange it (bought it new from O2, so it was under warranty).
None of the screen alignment fixes I tried made any difference. The problem was also temperature dependent - when the Trion was cold, everything was okay. Leaving backlight on and listening to MP3s for five minutes was enough to make the problem appear - first, only a few fake 'taps', then more and more, and eventually the screen didn't recognize any of my taps at all.
So it seems to be a hardware issue. The only software solution I could think of: back in WM 2003 days, there was a registry setting to increase/decrease the touchscreen sensitivity. If it still exists in WM5 (don't know, sorry. Others may be able to tell you), you could try setting it to be quite insensitive. Might help.

Thanks for the reply, now that I think of it, it only happens when it's warm. Looks like I'm SOL. Oh well, I guess ill put up with it until the iPhone comes out.. ill try loosening the screws too.
Your case is putting pressure on that part of your screen. It is not device specific. Slip a piece of paper under the case to check for clearance. I use under the case screen protectors and have seen this before. You may be able to simple pry the case and create some clearance.
I have exactly the same symptoms. It seems the registry settings do not exist in the Hermes to adjust the sensitivity so I am thinking return for replacement must be the only option. Argh! I feel defeated

The iPhone? You're going to actually exchange this beautiful piece of full-fledged mini-computer &phone in one goodness for an iPhone? Note: This was not meant to flame anything or anybody. If you feel that I have, I deeply apologise.

I've inserted a small piece of plastic between the frame and the screen (one month ago).
Here you will find a resume of proposed working solutions

Can you tell us the serial of your Hermes? (HTC62xxxxx, 63, 64)
That is the same problem I had with my 8525. I tried ALL the solutions here in the forum but nothing solved it. I finally returned it to Cingular and they gave me a brand new one with zero hassle. Two weeks in on the new one, and it's working like a champ (knock on wood).
the S/N is HT657xxxx
Nothing is putting pressure on the screen, I've pried some clearence between that part of the screen and it still does it. I dont even have a Cingular account, so I doubt they'd help me
My only other option is to take it apart(following the japanese website instructions) and see what's going on.. Maybe something underneath the screen is doing it? I dont know..
Oh yeah, not only did i loosen the screws behind the screen but I completely removed them and it STILL does it. I found the registry setting for screen sensitivity and lowered it from 7,xxxx to 5,xxx and it did nothing..

Unfortunately this sounds like the heat related alignment problem. When the device gets warm e.g when using wifi or charging say when connected to Active Sync, the heat causes a small internal expansion. This puts pressure on the edges of the touch sensitive screen.
If you have a warranty, use it, because there is no guaranteed fix.
If you don't have a warranty then the Wiki here outlines the things to try. Essentially for you I think it would be to unscrew by one quarter turn, the two screws on the back of the screen. Secondly, the business card trick of running the corner of the card between the screen edge and the bezel of the casing. There is a thin rubber gasket in there and the card can be used to free up a bit of room. This may cause small rubber granules to come free. Don't leave a lumpy mess of granules in there though. Best clear it right out. This is a warranty voiding procedure!!
Replacing the LCD is not likely to improve matters as actually the screen is probably fine, It's the pressure being put on it!

Thanks so much Mr.Michael Channon,
I tried all idea on the wiki xda but can't align sceen, the screen don't respond, after turnoff screen & charging about 5minutes screen working correct, but only working for some minutes.
I don't know what's is trouble. Everybody can help me...

Well, as I said above it sounds heat related and there is no fix other than the things you have tried - you need a replacement. Someone on this board ended up keeping the device in the fridge so they could get half an hour from it before it conked out again. It's a replacement job IMHO.

I check temperature by BatteryStatus tool is : 45.7C (temperature is normal or not).
What is gets warm, CPU, VGA...
I think LCD hots not influence touch sensitive screen, becausse lastime I use XDA IIS device very host when use wifi but screen no problem.

Screen Accuracy Problems

The touchscreen on my titan is acting very problematically, with the screen slowly getting more and more inaccurate to touchscreen inputs, it's getting to the point where i have to use align screen 3+ times per day, and it's incredibly upsetting, is there any fix for this, or is it a hardware problem?
I'm not sure what it is but I too had that problem. After I flashed to DCD's 3.0.1 ROM,, the screen seems to be more stable. I still have to align screen every now and then. Do you you use your finger instead of the stylus? Sounds weird but I do that a lot and that might contribute to the problem.
Yeah, I do use my fingers on the screen a bit, with PointUI's Home, I don't see how that could cause it though o.o.
My I760 did that on two different phones. So i just got the xv6800, no problems yet except the ****ty video drivers-Or lack there of.
Okay, at this point the screen is going nuts, I'm probably going to have to send it off to sprint for a replacement at this point, as within 20 seconds of aligning the screen it's off by a good 5mm, and that number keeps rising.
Is you screen dirty? Along with using my fingers, my screen was dirty also. I just used a dry towel and clean the screen by blowing hot breath on it. Also, I bought new screen protectors. Yes it does seem odd that using my stylus and having a clean screen helped with my problem. Maybe my new ROM fixed the problem, I don't know. But its not as bad as it was before. Good luck.
Yeah, my problem was getting exponentially worse, off by about 6mm or so every time I'd align the screen, so I just returned it on my insurance plan.
Stylus vs Finger
If you are aligning your screen using the stylus and then using your finger for gestures and such the screen response is not aligned. You have to align with your finger in order to get a more accurate response because your finger covers so much more area than that tiny stylus tip.
I would alternate back and forth between the two, but to give an example of how severe the problem was getting, I would align the screen (with stylus) launch a program, and -already- the screen would respond about 4-5 millimeters down and 2-3 millimeters to the right of the stylus, which would make various tasks nigh-impossible.
I had the same issue and notice that it was mainly due to the fact that my screen was dirty as mentioned before. Sometimes you may even notice that your screen may not be dirty but remember that oils from our fingers and especially our ears when we talk can cause the alignment issues. Perhaps you can even change the screen protector and see if this helps. This should fix all of your issues assuming it is not an actual software problem. The one time that I did find the alignment to be a software issue, all I had to do to fix it was to callibrate the screen in both standard and panoramic view. I hope this helps...
Nah, it wasn't that, I tried cleaning off the screen with a microfiber cleaning cloth and everything, even removed the screen protector to see if that was causing it, it was a hardware defect.
Well I can say this.. I used to work for Sprint, Nextell, Verison, and ATT at various points. I know that with more of them, they usually send you out another device and you send your back. The think I love about ATT is that they will do this with a No Questions Asked policy except for the standard one involving abuse, water damage ect. After 3 defective devices, they will automatically upgrade you to another device.... Please make sure that the reasons are lagitimate so that this policy does not change but if you need to go through the hoops to get a better device that works.... Have at it. Do not take it to a store unless directed by the telephone people. Many people feel like they are techs because they own a ppc of some sort but they are not the ones that make the ultimate call. Let the corperate people make the decisions. Once you receive your device, immediately stress test it with all of the things that you will be doing with your device. Load and unload software, ect to make sure it works. If ther eis an issue, it ie better to notify them within the first 72 hours. I hope this helps again.

Hermes White screen

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 !

Hermes/Schaps 4.31/Orange CH
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.
