i have a tmo wing and the screen has gone dark. problem started as occasional discolored parellel lines or completely white, then by sliding up and down the screen would return to normal. searched theads and found possible cause; loose cable from screen to mobo. i obtained the service manual, dissasembled the device checked all connections, reassembled and the screen is still dark. the device does power on and funtioned properly before the screen whent dark. the phone has not had excessive wear and tear, no vissible damage to the screen or cables, no water damage, original ROM never flashed/moded in anyway completely stock.i searched the threads for an answer but have come up empty handed.please, any links to similar topics, help, opions, or general knowlage on the situation would be greatly appreciated. THANK YOU!
More than likely either your screen, backlight, mobo or any combination of the three is just faulty. You may want to try a new screen first as they are the cheapest component and it includes a backlight assembly. You can get em off ebay for like 20 bucks USD.

Thought I'd try talking whilst going for a jog and managed to get some sweat into my XDA Mini. The result: the LCD still operates, but the backlight is broken.
I took it to a repair shop to see if they could repair it but they say I need a full new LCD - not so cheap. The guy seemed a bit dodgy so I thought I'd double check people's thoughts here before I go and spend the $150 to fix it.
I'm sorry if I'm insulting your intelligence, but have you tried holding down the power button while the screen is on? The backlight can be toggled on and off by holding the power button down a few seconds.
Just making sure!
(Eg. Check your floppy drive before you decide that the hard disk is dead - store attendants can actually forget things like that)
Haha,
Yes I have tried everything relating to normal backlight usage, including a hard reset.
I know the backlight is stuffed because for a while it would turn on for a sec before turning off, then finally it went kaput.
Well the backlight probably is stuffed. And $150 is a bit steep for a new screen, but I doubt you will find any better - though if you want try eBay. I just searched eBay US for 'xda mini LCD' and got a range of LCDs from $70 to $100.
The installation isn't too hard, as long as you're careful - it just involves opening the Magician (which takes patience, but isn't too hard or risky), unplugging the old screen, detaching it, and installing the new screen.
Darn,
I found a screen for AUS$115 delivered on ebay.
Is there any way I can tell if I have the black or yellow screen connector without opening the phone up (I'd prefer to have to open it as few times as possible). My guess is that it would be one of the black ones as I think it's an earlier model.
Hey maximus, I know it's been a while. Did you fix your screen? I've got a Trinity with me (also known as Dopod D810) and I put a new screen into it. It worked, but after a few weeks, the alignment went off and would not reconfigure no matter what I tried. Then suddenly, the backlight went dead but the LCD still worked (I can see the content on the screen if I shine a torch on it). I'm an experienced phone repairer but I thought I'd check to see if you did anything to fix your original screen.
I've got the phone open - the connectors are fine. I've tried applying light pressure to the sides of the LCD, hoping that maybe it was just a loose connection inside the LCD, but to no avail.
Looks like I'll have to buy another LCD
hey i'm have=ing the same problem !
there are not any option but new screen
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.

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.

If anyone can offer any advise/assistance, it would be greatly appreciated!!
I have 2 AT&T branded 8525 phones. Both have issues and I assumed I could make one good working phone from them.
Phone 1 had a touchscreen issue. It is not responsive what-so-ever. I tried the credit card trick, cleaning out the edges, hard reset, soft reset, etc... nothing seems to make it respond at all. Reflashed the ROM, but of course I am stuck at the "Touch Screen to Begin" screen.
Phone 2 works just fine, but when plugging in the mini usb charger the screen starts to fade to white (with many vertical lines appearing...but eventually the screen goes to white). If you wiggle the charger, it will clear up, but then go back to the fading white screen. If you leave it long enough on the white screen, it will lock up.
So I thought I could take the known good LCD from phone 2 and put it in phone 1. Yesterday I took both phones apart to do this. I placed the good LCD in the phone that had the possibly bad LCD. Put it all back together and found the touchscreen still does not work . So perhaps the LCD was fine and it was something else. I then decided to just take the motherboard from phone 2 and put it in phone 1 along with the LCD I just replaced (effictively moving the lcd and motherboard over to a new case). Same issue... touchscreen does not work. I assume moving the parts around eliminates a loose connection of some sort. I did make sure the ribbon cables were properly aligned and secured well. I am guessing something is wrong on the motherboard.
Does anyone have an idea of what could be wrong to prevent the touchscreen from working?
Oh...moving both the motherboard and lcd with the whitescreen issue(phone 2) over to the other phone (phone 1) casing didn't change anything at all either...so I assume that is not a connection issue with the cables. I also looked closely at the mini USB connector on the motherboard to see if there was bad solder or something that was making it act up. I am guessing bad hardware in both phones, but was hoping I could somehow make one of these phones work and junk the other. Sounds like I may have to junk both as the cost of parts is probably is silly.
Thanks for any help!!

I need help...
My T-Mobile MDA can power up but it will just stay on a white screen & after awhile, the backlight time-out & swtiches off.
Tapping the screen or the power button will bring it back on.
All the buttons seem to be responding & the system sound comes on when I press some buttons.
What might be wrong?
Several soft reset will not bring me to the standard screen.
Is it a hardware issue or software issue?
Please advice me what I should do to recover from this situation.
Thanks!
konker
Update:
I finally performed a clean reset & the standard WM5 "tring" sound came on.
At least, the system board is working fine.
But nothing appeared on the screen except for the greyish-white background.
I also brought the MDA into the bootloader mode but I don't see the Tri-colour screen.
What should I do next?
I noticed from the MDA Service Manual that there's a flex board for connecting the screen/front panel buttons to the system board.
Could that be cause of my problem? Or is it the LCD screen giving me problem?
Please, anyone who has experience with this issue, I appreciate any help I can get.
TIA!!
Is your MDA out of warranty? Do you have insurance? If no and I were you I would probably take it apart and check for a loose or bad connection. You got the service manual you should be good to go.

bendog2784,
My MDA has no more warranty nor insurance.
I took the plunge & disassembled it.
I made sure all connections are clean & tight before reassembling the unit.
The screen still stayed greyish-white.
This morning, I screen suddenly turned on but for a brief moment.
It seems that when I slide out the screen (or slide out the keyboard), half way through when 2/3 of the k/b is exposed, the screen looks just as it should.
Beyond that it will blank out, kinda like a device having been put to hard reset from an operational state...except that the backlight stays on & then greyish lines start to appear.
So now, I'm not sure if it's the screen that's causing problem or the flex cable.
The flex cables are very hard to find where I'm & very costly too, judging from eBay auction listed.
Would appreciate any help to revive the screen of my MDA.
Thanks!

What happened to your LCD that prompted you to replace it?
Did it crack?
If mine was cracked & there were fragmented display showing through, I would have gotten a replacement LCD with no questions asked.
However, in my case, the LCD is not showing anything other than a greyish white shade no matter what I do to the hardware.
I'm not sure it is a LCD problem as I mentioned above that yesterday, I got it to work for a short period of time at a certain position.
That said, I can get a replacement LCD for my MDA for less than US$25 here.
If it is an intermittent problem (as you described) I'd check the flex cable again.
try to reseat the connector that goes to the LCD (the large one that is locked in place with orange tape and the little brown clip on the connector itself).

hi im having the same probs with my vario, have you havd any luck sorting this out?
chrisakak9
Ok I need help from the gods of xda
I dropped my tilt the other day. When I picked it up everything seemed fine, yet the screen was completely white. No signs of cracks or a broken lcd. So I've tried the following: Soft reset, Hard reset, took out the battery, took apart the phone and disconnected the lcd and then re connected it. Still the same problem. WHITE SCREEN!
I can still receive/make calls, when i touch the screen in places where i remember the menus to be it still responds due to the noise, also the open and close noise still sounds.
The phone was bought new on Ebay, so i don't have a warranty through them or AT&T. After much research I hear people saying the same has happened to their phones as well and that there is a ribbon or flex cable problem. Something about still giving power to the LCD but not data, thus the white screen.
Now what I dont understand is do I need a new LCD because it has that ribbon/flex cable on it???? (link)
or
Do I need this product?(link)
Both contain a "flex cable" so im confused and frustrated, someone please help! any ideas would help

I am curious about this as well. I have a friend who has a hermes and he mentioned to me that that his screen was starting to go white like explained here. I look at his phone and I also noticed that the bottom hardware keys were not working at all.
I am wondering if this same ribbon cable for the LCD would also be the same one for the bottom keypad and if I fix the screen the keys will become active again.
Anyone have any experience with this?
Thanks,

Tuck in for a long read and perhaps no single answer for all cases:
http://forum.xda-developers.com/showthread.php?t=303872
In short, yes the d/pad cable and LCD screen connections are linked which is why it is not uncommon for the white screen to show up when the d/pad is not working.
To the OP - I would just point out that if you get the white screen after a fall it may just be a loose connection at the d/pad and no need for new parts.
Dismantling instructions here:

But let's not start discussing the white screen here, please use the first link I gave above if you need to post.
