.:: HELP Appreciated ::.
Hello Tech GURUS,
I returned from a long tour (I kept my XDA EXEC at home) & found that my XDA EXEC has got a problem of WHITE SCREEN!! Nothing is Displayed!!
May be brother's childrens or anyone of my friend accidentally did it in my absence(Sorry I'm NOT Sure). May be they pivoted (Turned) the screen in a WRONG DIRECTION!
That doesn't matter WHO DID IT, But the problem screwed my head & I started to trace the problem.
Symptoms:
1) Only WHITE SCREEN(with LCD Backlight), Nothing Else.
2) Charges perfectly through USB & also from Charger.
3) When I connects it to ACTIVE SYNC, it Syncs fine & I can able to explore the files/folders. Copy from & to the handset memory is also works fine.
4) Tried to enter into BOOTLOADER Mode(by pressing Light+Power+Reset), there also got a BLANK SCREEN (NO LCD Backlight).
5) TOUCH SCREEN detects TAPs & make sounds (Tick Tick), That indicates Touch Screen Working fine.
6) Qwerty KeyBoard Works fine. I don't know at what extent, since I can't see nothing on screen. But when I press a key on QWERTY Kbrd, it sounds Tick.
7) Transfered(Beamed) a CONTACT from my another XDA IIi & found Its accepted the beamed data.
8) Volume Up/Down make sounds (Tick, Tick...).
What I Did:
1) Removed the Battery & re-inserted & tried to BOOT it. NO result, just a WHITE SCREEN.
2) Purposely Tried to Rotate the Screen in Wrong Direction to test the loose contacts of co-axial cable.
3) Lastly Dis-Assembled the whole handset (Removed all parts 100%) & Re-Assembled it. But the Problem remains SAME.
4) Dis-Assembled again & this time I tested the LCD Co-Axial Cable's connectivity from MainBoard side connector to LCD Side Connector. There are 2 Cables which connects to LCD. One is 30 Cores Cable & Second one is 40 Cores Cable.
I Successfully tested 30 Cores Cable(Actually it used only 28cores cable, remaining 2 points at connector are DUMMY) & Second 40 Cores Cable I'm UNABLE to Test Since I lost my patience while connecting my Testing Meter to Hair Line sized cores & in just an 10mm connector got 40 cores!!!
5) Observed all cores which passes through SCREEN ROTATOR BASE Hinges & found there is NO physical Damage or CORE CUT.
CAN ANYONE HELP ME TO SOLVE THIS WHITE SCREEN PROBLEM?
IS IT A HARDWARE BASED PROBLEM? OR SOFTWARE BASED?
IS IT A PROBLEM WITH DISPLAY CHIP(IC) ON MAINBOARD?
JUST CONFUSED & SEEKING HELP FROM TECH GURUS.
THANKS IN ADVANCE.

This seems to be a hardware problem. Check connectors in the display housing first. This unit is quite easy to disassemble.
Before you start, you should have a look in the universal SERVICE MANUAL to check out how it gets torn apart .
If all connectors to the display are right in place, but your display still shows nothing ...open the universal body too.
Folow the steps in the manual

White Screen
Hello, this is my first post. May I first just say how great I think this site is, the guides on here really are useful to beginners.
With regard to the white screen, not sure if this helps, but during dismantling of my various PDAs, I managed to connect an LCD ribbon incorrectly, I kind of forced it in & folded one contact over, resulting in white screen. Disconnected, straightened & refit. Hey presto, works like a charm. Hope this helps.
I had the issue, had to buy a new flat cable
It is rare to actually see the damage to the cable, because the damage is inside the insulation....
Best regards!
On the topic...
Hello!
I have a similar issue with my Orange SPVm5000, except that mine will work for up to a minute after a hard reset before going to a white screen.
If I hard reset pressing the left+right+reset keys, the device shows the boot screen and sometimes ever goies into the initial setup but then all of a sudden it goes white. I've opened up the screen and verified and reconected all connections but still the problem persists. Also I've noticed that its not any action I make that causes it; more like a heat/timing issue. Per advice above, I will check the connections in the body but does anyone have any other ideas?!?
Thanks!
Greg.
I have a similar problem. The story;
I purchased an orange branded M5000 on flebay described as second hand in fantastic condition blaa blaa.
When the phone eventualy turned up it had no manual, the outer sleeve of the box was missing and the wrong usb cable was supplyed (one of those larger usb plugs you usualy get for printers.
I have shedlooads of cables and rely wasn't bothered about any of these problems at the time and went about charging the phone (it was totaly flat)
When fully charged I stuck my sim in and poweded her up the phone works fine in portrate and landscape view but as you rotate the screen so it is inline with the keyboard the screen fades to white about half way.
I contacted the seller who basicly told me the phone is second hand so sold as seen!?!?!?
I have flashed various roms on it to see if it was a software fault but nothing.
I think this phone had been in storage as its battery was totaly flat and incorrect accessories suggest the seller didn't check it before shipping. So I believe there is a problem with this phone that occurs when stored.
Sorry for the long post
Have you flashed any rom or just had this problem ...
my conclusions:
1. If you have flashed a new rom to your universal, try to reflash the original rom, it works for many users.
2. If you havent flashed any rom, maybe its a hardware problem.
2.1 If you just used it in a bad way, (ie: rotate screen in wrong way), dissamble it..
2.2 If you have let it on a heat, weat, etc.. place.. maybe the mainboard got a cut-circuit.
Saludos
I tryed a couple of popular WM6 roms (I forget whitch ones) and returned to the genuine Orange WM5 rom. So I doubt its a software fault.
As far was extreme conditions go the phone was well packaged when posted I will gove that to the seller SO unless the eposure happened before shipping I don't think thats to blame ether.
I think the wire in the swivle joint is failing and will continue to get worse as the joint is exercised.
Try to clear it up..
Hi there,

Sounds like the image could not be loaded completely.
The framebuffer is initialized correctly after cold boot, but afterwords booting into wince fails.
So maybe it's pure software issue (flash content is corupt -> image is broken).
Other possibility: Some region of your flash is damaged (more hardware related).

Looks to me like a typical cable issue. Maybe someone twisted the screen the wrong way!
So this is what i guess at least.

White screen
99 % of these white screen faults is a typical cable issue. And you don't have to twist your screen wrong way to have this problem, also.... just twist it too often First you have to see if the device is working, apart the screen.... call the number of your phone see if it is just screen related problem. Broken display cable will leave your device oprational, you just don't see the image.
I know it is "less painfull" for people to think it is a software problem.... (The "it would not happen to me" syndrome ) but sometimes things just brake, and moving parts are most risky...
The fact you don't see the damage is of no importance due to the size and nature of the damage. Don't expect to see broken wires in the cable. And even if you check the cable by you instrument, somethimes it will show you it's ok, but in some positions it will loose contact.
Try a different cable... that way you'll be sure.
Best regards, and all the luck!
"Looks to me like a typical cable issue. Maybe someone twisted the screen the wrong way!"
I agree and luckily, finally paypal do as well.
It is being boxed up to a red faced seller as we speak.
A happy ending for me (speaking to soon?)
i hav the same problem as u "HELLCRUSHER" and i flashed also but was not able to cure
still hav this white screen ..
Found this link for some where selling the screen cable assmebly.

Hope this is of use.
The screen on my MyTouch Slide shattered and I ordered and installed a replacement (this is the outer layer/digitizer). No issues there. But now the touchscreen functions are out of whack. It responds but there are dead areas, it scrolls choppily and acts like it needs calibration.
I'm not sure if this is a hardware or a software issue. Nothing but the outer screen was damaged initially (as far as I could tell). I'm wondering if:
This could be a contact problem? If the digitizer wasn't set properly on the LCD, could this be a result? (I disassembled and reassembled the phone after this problem began to try and confirm this but the problem persists)
If the phone needs some kind of software calibration or adjustment? I did a hard reset and wipe after installing, but no improvement.
ROM issue? I am running Cyanogen RC 7.1
LCD broken? Not attractive, but possible.
Any suggestions anyone has would be helpful. This isn't my main phone (and it's probably ready for the Shoebox of Retirement) but I'd like to get it running well before I give up on it.
Thanks!
Hello guys,
Around a week back, my MT3G slide touch screen got unresponsive for a while. I rebooted around 2-3 times and thankfully the touchscreen worked fine.
Now, I am getting this unresponsive touchscreen more often and I have to pull out the battery from the phone and turn it on again. The last time this happened I had to do this about 8-10 times before the touchscreen would respond. I have no problems with my keypad, 4 buttons or the trackpad, just the touchscreen
I also did a factory reset and erased all the data that I had on my phone and SD card.
EDIT : I just figured that the touchscreen sometimes starts working if you slide out the keypad. But once the keypad is slid back in, it's back to being unresponsive.
My phone is out of warranty so I can not get a replacement I think.
Does anyone know what could be the problem for such frequent touchscreen unresponsive behavior. After a couple of reboots, everything returns to normal.
Any ideas ? I would appreciate any help..
Thanks a lot...
you got a broken ribbon
Hi there,
Do you mean the slide rail flex cable or the digitizes flex cable ?
Thanks
flex ribbon cable
I would say it's the flex ribbon cable which connects the motherboard piece to the screen and home button piece. I've purchased several "broken" my touch 3g slides from ebay that had either the screen shift problem when the keyboard was slid out or screen that was unresponsive/wouldn't come on. Both problems were fixed by purchasing an inexpensive flex ribbon cable like item 170747702766 on ebay. I watched a video and followed along on youtube /watch?v=-jgFHuVWlig (stop at 7:27 and reverse the process). However, my most used mt3gs is now starting to have the screen shift problem again and needs a new cable... it didn't last as long as I had hoped.
Did you try any custom roms?. reflashing/updating the device?
I guess it must be some driver issue!..
i have the same problem.
Could you fix it?
Seems to be a common issue. I've described the process of replacing the flex ribbon cable here - it's not a rocket science. Or just bring the phone to a serviceman who will do the same (if you lucky enough he could even have a spare cable, but I'd advice you to have your own bought from ebay to be sure).

Thank you for the information but another questiion that I do have is where would one get a serviceman that would repair or help repair a phone, usually the technicians are attached to the different cellular carriers and if one dosen't have a contract with them they are not likely to help repair your phone even if it is for a fee. Do you know any serviceman?
Yesterday, I was just using my phone when the touchscreen suddenly stopped responding in one area. Its a bout a 2m wide strip running across the phone in portrait mode which does not respond. Originally I thought it might have been something to with the custom rom I installed last week so I completely wiped the phone and reset it to stock rom. I then ran the service test via *#*#7378423#*#* and ran a touchscreen test. This sowed me exactly where the digitiser was unresponsive.
The strange thing is that it sometimes works but more often than not there is a defined area where it just will not respond. Anyone know what the exact problem is?
By the sounds of it, you probably need to replace your digitizer. You could try taking it apart and try checking the digitizer's connection. Mine ended up getting loose, and the screen ended up being unresponsive unless it was tilted a specific way. If you need a guide on taking it apart, there are some fantastic guides on youtube detailing the disassembly process.
i am having the same problem..... replacing the flex cable will tell you if it works. Hold tight
Hello community,
due to a water incident I had to replace some hardware parts as microphone and finger print sensor.
The navigation proximity buttons do also not work, but I did not replace them.
After this replacement, the phone worked 3 months fine....then I replaced the main camera because it didnt focus anymore.
Since the camera replacement I have very bad wifi reception. When I am right next to the rooter, it is working but unstable. Thats why I suspect an antenna/hardware problem or another hardware issue. I did replace the black coax cable (also a used cable) next to the battery already, but this did not resolve the problem.
On the software side I did a complete reset. Actually twice because I had to unlock the bootloader and then did a reset. Also not resolving the problem.
- I am now wondering, weather there are more or different wifi antennas in the onplus 3 except the black coax cable.
- Does anyone have experience about the sensitivity of those coax cables? The replacement cable I have is also from a used phone and has some usage marks.
- Anyone another Idea, where the problem can be?
Thanks for any suggestions!

The problem can be the constant opening up of the phone and meddling with it.

I have the same problem with my oneplus 3, i too had to change my back camera because it didn't focus, which after many attempt didn't work and i ended up using a magnet right next to the camera.
I purchased a coax black cable but it didn't solve anything.
I also have switched between a numerous amount of rom and i can tell it's hardware.
So it's either the main board that suffered from the chirurgical operation we had to do or the back's antenna that are faulty, i don't think removing the camera would make any difference.
My wifi reception is really bad and i can't get a decent bandwidth even right next to the wifi...
I'll have to re-open it to change the amoled that just broked so i'll keep you updated.
Changing the back of the phone can make any difference?
Thanks!
