8525 White Screen of Death - Is there Hope?

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

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

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

hope the best

i tried this and it worked for me. i also pressed alil hard around the d-pad and heard a pop. i think it poped back into place.
thanks

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.

White screen, back light off,... repaired

Dear friends
After opening my Hermes a few times I encountered the white screen, I disassembled and assembled again, the display was completely off. I thought the flex cable could be wrong. So, at first I tried to use a soldering gun to seal all solderings (Photo 1). This time the phone showed a part of display. Because, the symptom was not the same, I guest contact between the flex cable and the mainboard had problem. I used point of a knife (make it blunt first) move down to push contacts out (Photo 2). Then I assembled my phone, everything returned normal. (9h in the morning to 11h in evening to make my heart cheerful again ).
I write my experience here for someone who open their phone and encounter the symptom like me.
Good luck.

Sadly didn't work for me. Stil no backlight!

I had a problem with no backlight but fixed it when I replaced the flywheel. I was trying to update a replacement jasjam I'd bought off of ebay but when I replaced the new flywheel with the old the backlight wasn't displayed so I tried the old motherboard with the new flywheel and the backlight was on. I don't know how it affects the backlight but it did. If you can get your hands on a cheap bung phone or have a REALLY trusting friend then try that.
Cheers...

Sorry mate, what do you mean with the flywheel? English is not my mother language and what I have found in the net for that word does not mean anything to me. Can you provide me with a better explanation? I do have the same problem as the guy which writes above you.
Cheers

The little wheel on the side of the Hermes. I replaced the board That has it on it and it fixed the backlight issue.

Help with diagnosing LCD problem

Do I blame the onboard video or the LCD itself for this problem? I've taken the phone apart and re-seated the motherboard connections, which was no help. If I connect using EveryWAN the phone appears to be working fine, in fact I flashed the T-Mobile ROM and than the Button ROM thinking it was a IPL/SPL issue. Even if I try to start in boot loader mode the screen still looks the same.
Just trying to decide If I need to replace the motherboard or the LCD.
Thanks,

Bump back to the top!

Screen seems intact without any damage visible, no cracks or out?
Had this problem once with my old Universal, was the colour transfer wires that were loose, but pretty sure the Uni is totally different to our wizards.
Prehaps open her up and see if theres anything thats loose prehaps.

I had it opened and re-seated both the connecting cables, but no luck.

Ive had this problem with my wizard .. i couldnt find a solution. tho i didnt really try very hard. Basicaly just picked up another one on ebay for like £30 seemed cheaper than spending the time and effort fixing it. I think mine got progressivly worse. It used to do it occasionaly and now just it as soon as its switched on

i have a same sort of problem...
left of the screen fills with lines and the whole screen fades to white.
turning on and of the screen via power button takes it back to normal but then it happens again.
noticed it only happen in portrait so i have to set it to landscape all the time
for some rom and spl's it happens just a few times a day and others i cant use it in portrait.
If i find a solution it might be working for you to

Fading white screen of death
Could be the battery. Have you tried a new battery?

Solved.
The LCD itself was bad.

HERM200 front buttons + Strange behaviour

Hello guys,
All of a sudden yesterday my phone started acting strangely.
1. all front buttons are not working.
2. Green/Red buttons are always with lights on.
3. Phone works too slowly sometimes.
4. Green light that blinks usually does not blink all the time.
5. Camera does not start.
I tried with hard reset too. The phone is not with original ROM. It is now 6.1 but it was working fine for more than 2 years.
Please advice.
Cheers
Yasen

Did you get mosture / liquid into the d/pad board under the buttons ?
Mike

Hi Mike,
I am pretty sure that this is not the case. I don't remember such event. Also i havent drop my phone recently to the floor or something. It is really strange.
Cheers,
Yasen

Something more...it seems that the screen is not aligned properly. Also when I plug in the phone to the wall charger the orange lamp is not on but the phone charge properly.

So far everything speaks of a hardware problem I'd suggest you take your device to a service shop - unless you are a skilled in soldering etc., this is something you won't be able to fix at home.

i have the same problem too

Indeed it could be the connector between screen and d/pad daughter board as this is also integral to the digitizer that controls the alignment.
It could also be one of the other internal flex cables or the chip on the d/pad daughter board that is known for delicate solder joints.
Mike

I think I will take a part the phone and clean all contact points.
I will write later when I am ready.
Cheers
Yasen

Taking the phone apart did not help
There was quite dirt inside. I have cleaned it carefully. All connectors look okey to me.
On other hand the phone acts differntly every day.
One day the red/green pad is with lights on, other day only the Charging lights is on.
Any sugestions?
Cheers
Yasen

Looks like a broken flex cable or soldering... it might be not something easily detectable with a naked eye. Take a good magnifying glass and carefully examine the flex cables for any cracks, as well as the state of soldering joints, especially in places where the flex cables connect to the mother/daughter boards as well as on the D-Pad board (which receives most mechanical pressure).
If you dare to, turn on the phone while it is taken apart and try to VERY CAREFULLY "swing" the cables with a non-conductive tool to see if it has any effect. Aslo try to apply a bit of pressure (again, VERY CAREFULLY to avoid any damage) to different areas of the boards itself to locate the most probable area where the defective joint might reside.
But, again, unless you're skilled in electronics hardware repairs, the best you can do at home is identifying a potential problem.

[q]mayor problems after replacing screen wont boot[19 jan]

Hi i have a htc hd2 with gingerbread, my brother replaced my screen and it work fine the first time with the only problem that you see light in the corners because it didnt fit properly to the frame,
2 he tried to fix it so he used some glue when i turned on it freezed when booting and the color white was showing pink
3 he took it apart again to put it like the first time and it work but now the speaker stoped working so i used it like that for 3 weeks
4 then i told him if he could check the speaker so he took it apart again with no luck and now it freezes again when booting we have tried to find the problem with no luck
do someone have any clue for what is causing the problem please help me
another thing since replacing the screen the first time you turn on the phone has to be with the ac cable because it wont do nothing with the on button after that the button works fine
hope someone can help me and sorry for my poor english

it seems like you might have a loose cable connection somewhere, like the loose flex ribbon or broken sockets. Your only bet is to disassemble your HD2 and assemble it,but this time around, you might want to do it according to proven methods and go step by step. Refer to the links below to help you:
http://www.ifixit.com/Guide/Repair/Installing-HTC-­HD2-PB81120-Screen/5651/2
http://pocketnow.com/hardware-1/official-htc-hd2-disassembly-assembly-training-videos-leaked
if proper disassembly and assembly do not work, then im afraid you have to replace your flex ribbon or get a new screen. it is often hard to troubleshoot what exactly is causing the problem unless you see a visual break in connections. take a really close look at all the connectors that are involved with the screen: the locks, sockets and cables.
do try the above and good luck. hope this helps.
