Blank screen - 8525, TyTN, MDA Vario II, JasJam ROM Development

I have been using CRC 12.11 for a while. A strange problem started all of a sudden. My screen went white although it is working. Soft reset didn't solve the problem. Hard reset solved the problem for a while and then it came back. I noticed this at the time it happens. While everything is fine, the screen fades out, a few lines like scratches appear and then the screen stays white. I hear system sounds, the phone rings but no display. What has caused this?
I flashed another ROM but when my phone restarted it was still white. I hard reset and now I am waiting. If it reappears, it means it is a hardware problem right?

I had this same weird issue once on my rom, i think it's because of the Big storage bug.. Flashed OEM rom and went away.. only saw it once!

I reflushed several ROMs that I used to have before without problems and still have the same. I can't install OEM, I think it's because of the bootloader version but I don't remember exactly the procedure to correct this and I don't know if it's worth the effort in downgrading to OEM.

Another thing I just noticed is that the screen is not aligned in the center. There is a small gap on top of the screen as if the image has moved downwards. Maybe this is the cause of the problem. Noone had similar issue? I don't believe it has to do with big storage because I have been using it fot a while and this never happened before, not even once.
Any ideas will be apreciated as my only choice right now is to buy a new phone.

same thing
i´ve been looking around and some people say is because the magnet in the pouches, affect in some way to the screen ribbon or something like that.

that is a common problem with the hermes, if u search the forum u'll find a couple of threads like this.
it's a hardware problem, next symptoms will be the green/red buttons and d-pad stoping to work

I know theres a few links in the FAQ about the white screen issue, its fixable in some cases.

problem solved!!!
i just took it apart, one of the ribbons which connect the green and red buttons was kindda folded also the connectors , so i just blow some compress air and tried to unfold the ribbon, put it back together and voila! like new. Just be carefull cause it´s like fragil.

same exact problem word for word
The same exact thing happened to my hermes. I guess I can attempt to put mechanical skills to work and fix this problem.

White screen

HI All, have an intersting problem, was surfing the net via wireless when the unit locked up. Soft reset and now all I get is a white screen. The unit seems to hard reset with the startup sound that the unit makes when you first start it up out of the box, but the screen stays white.
Any Ideas? :roll:
mmm.... Hard Reset :twisted:
HI Xeon,
tried that and still comes up with white screen, but does all the correct things re sounds but all you can see is a totally white screen.
You could try leaving it with the battery removed overnight but it sounds like a hardware problem to me, could be the lcd has died or the connection has come adrift for some reason.
I suggest u Upgrade or reinstall the ROM , maybe something happened to one of the files that should not be modified , anyway , u won't lose anything , u already Hard.Rstd .........
i had the same problem before..i did an upgrade that fixed it. but still have a backup even if its a white screen..after i upgraded i had another problem with the Storage Folder missing..and the list goes on..dont wory you'll know what i mean when you get it..
It happened to me the second day I got my O2 XDA IIs. Hard reset didn't seem to do anything... The unit didn't response to a soft reset either... It was just frozen... I removed the battery, boxed it up and was ready to return it. The next day, just before I was about to drop it off, I was curious and did a reset and everything went back to normal... It never happen to me again... Don't know what happened :?
I have the same problem...
The phone shows white screen white it can recieve & make calls, activesync can recognize it.. But the screen still white !!
Any other suggestions for helping solve this problem..
Is this means that the LCD is dead ?? or the problem in its connectors or it's a software prob. ???

Wierdest thing happened to my 8525 please help!!!

ok so i searched on the sites for a fading to a white screen problem but it looks like its related to the dpad... my phone was really low on battery last night it kept beeping continuously... so by the time i got to plug it in the screen started to fade to white... now the screen has vslight vertical lines and every time i shut off the phone with the power button and turn it on it comes normal but as soon as u touch the screen it fades to white!!! was this caused by the low battery. i fully charged it but still have the same prob. i tried clearing my storage and that didn't help..what do i do?
white screen
you will need to replace the board for the dpad.
ok thanks. is this the same issue that others are having as well? the wierd thing is half the time it works the other half it doesnt...
I had a similar problem. I had pressed the power button to check the time and screen was white! SR rebooted and after the first splash screen the screen faded to white. I finally founded a product called Pocket Controller http://www.soti.net/ (trial ver works fine) that allowed me to see my phone on my computer. I was then able to backup my data to the storage card. I reflashed the phone and it’s worked fine afterwards.
yeah man thats what happened to me exactly... im reflashing the official wm6 rom now... ill post what happens... thanks

damn it didnt work with me my screen still goes in and out when it chooses to. and it is my dpad b/c it stops working when the screen is gonna go..
Hi,
Try tightening the screw behind the red hang up button on the dpad. There is a component behind there which causes this problem. If tightening doesn't work try loosening. It's all to do with the pressure on the chip. Very odd problem.
Also try squeezing the bottom right hand corner of the phone and SR.
Bonkers solution for a bonkers problem but it certainly fixed one of mine.
Good luck!
yes, the screw tightening/unloosing thing works for me. same thing happened when i dropped my unit. i even completely dismantled it (managed to fix the microsd card spring). something loose with the connections.
niec guys thanks... i will try the tightening and loosening the screw... i tried holding down the bottom right and SR didn't work but thanks anway... i guess i have to buy a screw driver to open this thing up... god i remember when i had to take apart my mpx 220 im getting flashbacks!!!
Had exactly the same problem but mine was due to an phone shop employee dropping it. It would do exactly the same as yours. Sometimes it would work fine and once when I reflashed it the problem went away for a few days but if came back.
I used to control it using Soti pocket controller but them migrated to Net Support as that allowed me to control over wifi. In the end had to get it replaced.

Help my phone is dying!!!

I got my hermes from my friend, (HTC X01HT), she didnt want it because she dropped it and the ringer didnt work. it had only gotten unplugged, so i opened it, plugged it in, and had an awesome phone.
I dont think this is normal, but from the time she gave it to me, the screen made an awful highpitched ringing noise, (very uni-directional, it was weird).
Anyways...
now, the screen is just white. for a little while i could get the screen back, just by opening and closing the slider and hitting the power button a couple times.
Sometimes the today would display, then it would jarble up a little bit then fade to white, but i cant even get it to do that anymore.
Anyone else seen this issue? i'd hate to get rid of a perfectly awesome phone.
Thanks!
(also, if someone could post a picture of the device locked screen, where you have to enter a PIN to use the phone, that would be great, im trying to get into the phone with activesync, but its locked, and i dont know where to push the buttons.)
thanks!

Looks like the screen is unplugged, really. Maybe you need to disassemble further, like http://www.pdacenter.ru/razborka/razbor_hermes/ shows?
keep in mind, it worked fine for almost three weeks before the screen issue started... but i will try that when i get my hands on a small flathead again.
There's a whitescreen & D-Pad failure issue that can be caused by many things, including DROPPING the phone.
I wrote a guide about it which seems to be quite successful for many people.
http://forum.xda-developers.com/showthread.php?t=321163
so after trying a hard-reset, (which somehow displayed on teh screen), and clicking no, i was able to get the screen back... only this time with the moved screen problem, wrapping around at the top about 1mm.... and the buttons didnt work.
i tried your guide, but now im stuck at the white screen again... :/

My front buttons dont work

Hello, what should I do? My front buttons sometimes dont work. I tried to flash official HTC rom, but it still doesnt work. But when I pres some of the left side button, temporarely the front buttons work. Have anybody some suggestions?
I have the same problem - front buttons "drop out". The only way to "re-initialise" them is to use the scroll wheel on the left hand side of the device.
It's definitely not Rom dependent. I've tried multiple roms (the official, Schaps (current), Faria, Shamanix, etc.) and it happens on all of them, so it's obviously a hardware issue. Not sure if there's a script that can be written to check and see if the keys are active, and if not, activate them.
Said to be BIG problem and possible onset of the dreaded WHITESCREEN SYNDROME....
Do a search on the forum and you might find out more...
Cheers...
I have exactly the same problem. The weird thing is that all LEDs work as expected, even the touchscreen works, but none of the buttons do, nor the ones on top neighter the ones on the bottom ... that's uncool :-(
i had the exact same problem, and in fact, its back again now because i didnt fix it properly
its to do with a loose d-pad connector. unfortunately, it involves opening up your handset, right down to the screen and reseating the d-pad connector and putting a small piece of foam or other plastic to keep it in place
good luck
Yeah, I get the whitescreen happening as well - but I thought that was a separate issue. If they are the same thing then I'll do the fix because I have the link to the whitescreen fix. Will post it when I get home
Here's link : http://forum.xda-developers.com/showthread.php?p=2238093
Cheers...
I just did this mod, but went all out. I had the exact same things happening to me as the original poster. I had replaced the cable between the screen and main body of the phone from a broken jasjam, and that didnt fix it. I had opened it many times to try and reset connectors without much luck.
After reading the thread linked by the above poster, i opened it up and put a piece of foam where the O.P said, but i also place a piece just below it, and on the cable connection to the screen. That was really loose and when i moved it, it seemed to cause the white screen errors also.
Further, i placed a bit on the long connector back in the main phone.
Working 100% now, no problems with front keys. Heres hoping i dont get the problem back in 2 days!! ill let you know. I just need this baby to hang on till the Touch Pro makes it to Australia.
I might give it a go - the white screen is becoming more of an issue for me now. The buttons have long been a problem and I need to fix it.
I'm also hanging for when the Touch Pro arrives in Aus

[Q] HELP! White lines on black screen HTC Desire CM7

A few days ago I succesfully (at least I thought so..) flashed my Desire to Cyanogenmod 7 using Amon-ra and it worked perfectly, until today out of nowhere my screen is black with a couple of white lines from top to bottom. One minute it worked as normal, and a couple of minutes later when I pressed the top button to unlock it, the screen was all weird. The touch functions of the screen seem to work as normal, I can unlock the screen, shut it down, power it up, enter my pin etc (blindly) but I see only the vertical lines so it's hard to check what's going on. I do see that the lines "move" when something changes on the screen, like when I unlock it, I see that the screen does react on it, but only some lines appear, move or disappear. For the rest, the sound works as normal when I turn op the volume, as does the vibrating.
I have a PVT4 S-on (thats all I remember) if it makes any difference.
Picture is from a camera, not a screenshot. Looks a bit yellow or so but the background is black, and the lines are white.
Does anyone know what it caused and what I can do to fix it? Maybe reset it or reflash it someway?
Many thanks in advance!!
Where's the picture?
You might want to give HTC a ring.
Request from puntchiel, a picture of his mobile phone:
http://dl.dropbox.com/u/13976378/P1050923.JPG
Hm I forgot the picture, my friend len posted a link for me, for Im not yet able to do that cauz Im a nub
Thx len!
Yeh, send it to HTC or your carrier. It looks so ****ed
Well, sending it back and profiting from my insurance is my last option cuz I wont have it back for at least a month. Does anyone know what it could have caused or what could be a way to solve this highly annoying thing? I can't imagine that it is a hardware problem that occured this sudden... And the screen is reacting to my input but it only shows the frikkin lines! So I hope that it is a software problem. I just have no idea how to solve it, so thats why I'm asking the pro's on this forum
And btw, if I'm sending it back I need to make sure that they don't find out of the custom software on my device. That leaves me only two options I quess, fixing it or completely smashing it... So if someone at least knows how to use a RUU or something via my PC (without having to use the screen of my desire), your help is very much appreciated!!!

Ohh yeah thats helpful; i am sure he did not think to contact htc himself
That picture recalls bad experience with my ex Nokia 5800xm. I had to replace display.
Maybe it is not same case but it looks same.
I have exactly the same problem, flashed cm7 on my desire a few months ago.
Worked all fine.
Then yesterday all of a sudden i had a black screen with white lines.
Maybe you, puntchiel, have found any sollution?
I'm sorry Hanswurst, I had my ensurance company pick up my device and they replaced the screen, so I asume it was a hardware problem. I wish I could help you buddy. Good luck with it!
