Possible issues of white screen? - 8525, TyTN, MDA Vario II, JasJam General

Hey guys, I've got a few questions about white screen issues.
What can cause it? On my first Hermes, after I've drown him, he started to show me white screen (probably, ****ed up FLEX).
So I got another Hermes with broken FLEX Cable [in another way] - display doesn't have any backlight; but I can see data.
Both of these pieces have got TOPPOLY display.
So I've ordered a new FLEX (for toppoly) from eBay ... after the flex came, i put in the less-damaged Hermes. But I got white screen.
So I sent it to repair center - they got white screen after changing flex too. And wanted to change motherboard (for lots of money - 2x more than second-hand Hermes), so i refused.
Now I'm wondering what can cause the bright white screen, if it doesn't have white screen with the flex-without-backlight?
I hope you can understand what I'm asking.
Thanks in Advance.

Well, if anyone got here tru search - http://forum.xda-developers.com/showthread.php?t=321163 - this fixed it.

cracked screen on my 8125. suggestions?

hi. i have an 8125 and i was painting and fell from the ladder. i wasn't hurt all that much but the the screen on my 8125 cracked and now there is bleeding everywhere inside my screen.
does anyone know if i can replace the screen easily by myself or where i can even get a screen?
i think someone was going to sell me a broken MDA (screen good) and wondering if that screen would work for the 8125.
thank you.
Hi!
There was similar discussion some time ago:
http://forum.xda-developers.com/viewtopic.php?t=51395
Actually I broke my screen too this weekend I ordered replacement from ebay, such as this one:
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=140005879931
I am going to try to replace it by myself according to Wizard service manual. In my case only touch screen is damaged - not LCD, but it seems that these come as one unit. If I will find that these can be separated, I will have spare LCD part. In my case I have O2 XDA mini s - I do not know if lcd is the very same as in Cingular 8125 you have.

Gutted for you m8. Hope you manage to get hold of something cheap.
Update to my previous post - after much tinkering I was able to replace broken touchscreen of my mini-s.
Some notes:
According to Wizard service manual there are two LCD versions:
p/n 60H00032-00M - LCD Module, (LTP280QV-E01 Samsung)
p/n 60H00037-00M - LCD Module, (TD028STEB1 Toppoly)
It seems that these are not interchangeable but I might be wrong. I was trying to replace my 60H00032-00M with new 60H00037-00M (whole module with lcd & touchscreen), however it did not work - LCD switched on but was all white. Then I managed to separate touchscreen from new module and replace it with my broken one. Seems that it is working now. It is possible to replace just touchscreen but care must be taken not to break it and some very fine soldering must be done.
To theorist - if you want to replace LCD by yourself you should check for exact part number of your LCD and find similar one - that should work.
So now I have spare and useless for me 60H00037-00M LCD Module (LCD only without touchscreen) that probably is in working order as I suppose that it is just not compatible with my mini-s.
In the US, HTC America can fix it. http://forum.xda-developers.com/viewtopic.php?t=49361&highlight=

T-Mobile MDA start on a white screen??

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).

OMG White Screen!

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

hi there, would it be possible to post the link to ebay item? i also need a new touch-screen.tnanks
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.

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

a user i dont recall now his name,fixed is whitescreen by replacing the camera,open the device and remove the camera module, reassemble to test.

Qtek 9000 screen with blue and white lines

Greetings !
I am the proud owner of Qtek 9000 for sometime now.
Recently i was given a second unit, that at first look has a broken lcd.
The person who gave me the broken Qtek 9000 said that it had fallen off and then started to have the screen problem.
When powered on, the lcd displays blue and white lines during the width of the screen and the backlit does not come on.
If i plug the device to a Win XP machine, its get recognized and trying to sync
I assume the device must be working and this is an lcd only problem, although i have not synced it.
After reading around the forum and looking at the service manual on the wiki, i have disassembled the unit to see if any of the lcd connects got loose during the fall.
It seems that all connectors are in place, so my next task is to find if the lcd screen or lcd harness (cables) are broken.
Does anyone have any idea what i should replace ?
I have the same problem with red and white lines
Do you find what is wrong ???do you change the screen?
Welcome to forums
Try to do a hard reset (instructions on the Wiki), if not working perhaps you have to replace it, have a look on marketplace, one member is selling one
Good luck,

Mi2S - Problem with new screen

Hey guys,
yesterday i changed the screen and digitizer of my Mi2S. Now, when i switch the phone - with new screen - on, the screen is just lightning blue (you can see it on the attached picture). Now i saw that on the Flex Cable of the original screen, there's written B04 and on the new screen there's a B01 instead. So, i think i have now a different version of the screen and not having the drivers for that. So, does anybody (maybe developers) know how to flash others drivers and where to get them from?
Thx already ahead for any help.

*already edited it into the first post*
Are you sure you connected both flex cables correctly?
From your picture I would think only the backlight is on and the screen itself is not active...
Would be my first guess...
(I have a Xiaomi Mi2s and did the swap myself, I didn't have any problems... + even if there are different screens, the SW should cater for it, otherwise we would have a different SW build for every screentype used...)
Hi, i send it to a professional repair center and they said that there was a small water damage (from wherever!?). As i now found a pretty ok priced Mi2S (where the camera flex cable is damaged) on Ebay, i'll just insert the camera of my old one into the "new" Mi2S and sell the Display i bought for my old one. Problem solved!
But thanks for the reply anyway!
