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..

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.
So I was shopping for pants today, but I forgot I had my Desire in my pocket (front right one, if you want to know).
So, my phone fell on the ground and the battery and the cover flew off.
I quickly bought my pants and rushed out to see the damage...
IT WAS HORRIBLE!
The thing didn't want to boot, all it did was flash the red and green LED...
I (somehow) managed to get into bootloader to see the damage...
That was ALSO HORRIBLE!
The recovery kept restarting (4EXT, the loading screen that says 'preparing boot') and all I could do was take out the battery...
Thank god, Fastboot worked, so as soon as I came home I started running the RUU (from fastboot)...
Again, HORRIBLE!
when the RUU said the phone was gonna reboot into bootloader, it DIDN'T - the LEDs just kept flashing!
So I pressed power+vol- and that did the trick, but after the RUU finished ... again, flashy LEDs...
So, is this a software or hardware issue, and how to fix it (other than going to a guy and pay him to do it, which I'll do anyway if you people (god, no!) don't know the answer...)
I think I'll go to Fastboot next and clear all storage...
EDIT: Held the power button for a few secs, and the HTC boot logo shows up...
EDIT2: THE BOOTANIMATION!!! FINALLY!!!
Still, I'd like to know what the issue was, since it seems like it'll work normally from here on...?
Seems like all I've damaged are the LEDs and the camera Flash (the camera says it's too cold to use flash...)
I'll heat up the battery and report again
P.S.
Sorry for the double post... My PC is laggy today...
EDIT: Can't boot into 4EXT, no matter what... I tried CWM and it worked fine, but 4EXT won't...
And just today, I bought a new SDcard so I'd have more space and speed so I could partition it...
EDIT2: Also, the battery doesn't want to fill up... The second I take the charger out, it shuts down... Looks like I'm in need of a new battery... (curse my pants' pockets for being so big!)
It won't be bad to disassemble your phone and see if some connector disconnected.
How do I do that...? Is there like a hardware manual somewhere...? Because I'll need to know what screwdrivers I have to buy (I'm all out anyways...)
Yeah, it's probably the connector, since I can hear something shaking when I shake the phone (or it's something broken... hope it's the first thing)
Otherwise, there's a little power button glitch when turning the thing on... The LEDs flash and I can only boot if I hold the vol- button (can't do anything, not even bootloader!)
P.S.
I was just waiting when you'd reply (oh, Great one!)
Youtube is a miracle...
You'll need TORX screewdriver (star shape 6 angles), a small one.
Took my phone apart, saw the drivers I need... Just gotta wait till morning so BauHaus opens up...
I saw the tut on how to replace the screen, so that will help... Other solutions WILL be YouTube, since I don't understand anything from those pictures (but the text part of the guide is great)
I found another glitch: The LEDs flash if charging even if the battery is 60 meters away... I don't believe that's a sign of a disconnected connector... Hope it is
EDIT: Installed SetCPU, and my battery has been at 0% for the last 12 hours (without charging)... And the phone works... It just won't turn on sometimes...
Picking up those screwdrivers at about 6 pm
Just one question:
Is it possible for a connector to break? And if so, if one is broken in my phone, is it possible to replace it...? (haven't gotten the screwdrivers yet...)
If not, do I have to replace the whole cable, whole motherboard or only the component of the connector...? Or even the whole phone...?
I just popped it open... Now what? I disconnected and connected every single connector, reassembled it and the LEDs still glitch... And the phone won't go beyond the boot logo...
Could it be the battery? I saw a new scratch today, could I've damaged the battery and that is what's wrong...?
EDIT: Disassembled it again, looking for anything unusual (note that I don't have a single clue about what I'm looking for...)
Looks like I'm leaving the Android phone world... for the next 4-6 years... :'( Good old Nokia, I'm glad I didn't throw you away...
And it appears I'm yet again talking to myself...
Anyways, I'm taking the phone to a check to a repair shop, so I'll know what's wrong...
EDIT: The guy in the shop said a check is free, so I'm just gonna chill and play Minecraft for the next few days until he calls
Meh... The guy at the store checked it (FINALLY!) and he said the motherboard was dead...
And that costs 200€ to repair...
Anyways, I went to another shop and got me an Xperia S...
Goodbye, developer phone
wow 200 for mobo, u could get a good second hand desire that aint pvt1 for 100 lol. ah well hope u get better luck with ur new phone
Sent from my HTC Desire
I bought my Desire a few months ago, in June, for 120€ (PVT3). It was used, but it was the only used Desire in town... (seriously, I was the only person with a HTC Desire in my town (with 200k people!))
Ah well...
Guess I'll be the only owner of a Xperia S in 4 years
well, i' have installed roms for a while and everything is ok, but in last days my phone sometimes stop responding, the screen doesn't turn on pushing the power button, but the funny is that apparently the phone still working, how do I know? if i have patience after a moment maybe 10 mins or in other cases is delayed 1 day the screen shows up in the last part where it was.
Now when I don't have patience and i pull off the battery and try to turn on the phone, the phone apparently turn on, vibrate, and then show the blue light and thats all , the phone still has keep in the black screen and I have to pull off the battery and repeat the process until the phone wants turn on
please help me this problem is really stressful
and a extra information..
2 or 3 months ago my phone fell down in a pool
maybe the problem is the battery? any help is valuable for me
So I can tell you 90% your Xperia Play suffers from a disease called "the flex cable damaged" disease. Your phone will have to undergo a surgery which will replace the damaged flex cable with a new one. Flex cable is the cable which connects the motherboard to the screen. Common issue for Xperia Play. Revert to stock, and I mean completely stock, then send to Sony Centre and replace for free if you still have warranty.
woww that was fast, unfortunately I have no warranty, my cousin throw me at the pool so i think he can pay me the flex cable... do you know how much is it?
by the way........rhank you sooooooo much
Er I am not sure about the price cause I got mine fixed under warranty. But I think it's not really expensive
So a tip for us is that open the slider slowly to avoid damage to the flex cable right?

Yep. Some people always push up hard (I am one of them ) then my flex cable is damaged.
I don't think it has anything to do with how hard you're using the device.
It has to do with how it was installed from the factory.
sometimes the cable can get bunched up underneath the screen and get a crimp in it.
My other spare screen slider cord has been crimped and i don't know how much longer it will last
but my other one is totally fine.
Guys I had problems too with my XP. One day the screen became all glitchy than i changed my flex cable and now the Device goes on when I push the on/off button the device thrills but no screen.
Any solution for this all ready flashed stock .TFT file.
Hey guys,
I think I destroyed my HTC One X. I just bought it a month ago from Ebay, and it worked flawless. At some point the display just turn off. I restarted the phone, heard the sound when it starts and even the softkeys worked. But the Display was still off. After after a few restarts the display turned on for a minute, just to freeze after that and turned off again. The phone was still on though.
However I've read a bit around and found out that it could be a cpu heat problem, which could be true because my phone was way too warm sometimes. So I removed the display and put a tiny little bit thermal compound on the cpu. Somehow I managed to rip off the connection cable to the display ... also I managed to rip off the little black cable near the soft keys. The soft keys still work though.
When I start the phone the starting sound comes, the softkeys blink when I restart the phone, you hear the volume buttons etc. So it seems the phone is fully working. Just the display or touchscreen is damaged.
Some pictures:
http://i.imgur.com/LQ4M2Gb.jpg
http://i.imgur.com/uWZTfNe.jpg
So, what can I do?
Do you think I could just send it to this site http://www.directfix.com/product/REP-0063.html and let them repair it? Or did I destroyed my phone too much already?
Thanks in advance.
Well,the top cable is ripped off,you can't do anything at this point.The bottom one just seems out of slot as far as i can tell from the pics.
Basicaly you can send it to the repair shop,but i don't think that you can only change the cables,don't really know what to say...Could cost you some to repair it.
I don't want to only change the cables. I want to use this full repair service:
"HTC One X Complete Screen Replacement Service (Includes LCD & Digitizer)".
So they change the cables and put on a new LCD & Digitizer as far I understand.
But do you guys think they will put back the other cable back in slot too?
Please just answer, do you guys think they can repair it if they put on a new screen & digitalizer?
I don't see why not,you can also contact them and explain them the situation.Those cables are quite easy to put back with the proper tools so you don't have to worry about it.
Hello,
I just got my N7 back from repair where they replaced the ME571K SUB_BD./AS board since the USB Port was not working anymore.
Luckily the port works now, but on the other hand the Touchscreen is not responding at all.
I tried restarting already without success. I also cannot reset the tablet since I got TeamWinRecovery Touch (and CWM 10.2) installed.
I can connect the tablet in bootloader and with "fastboot devices" it shows up as 077a744a.
Could anyone help me on how to flash or reset the tablet?
Ps.: This replacement was out of warranty, therefore I paid for it. The service center suggested replacing the mainboard (to make money) as well. Before I sent the tablet in everything was working just fine except mentioned USB Port.

I just flashed (with wipe) the factory image without success.
There's no response at all. Also when I try to get into recovery mode now the opened Android with the red exclamation mark shows up.
Is there a low level touchscreen calibration or something I could run through fastboot?
Anymore help would be greatly appreciated.
I'm starting to think they just put my motherboard in another tablet with abroken display...
I'd return it, it sounds like total screen failure.

That fallen android is just an image overlaid over the stock recovery menu. It just means you've booted into stock recovery. You can get the recovery menu by press/hold Power, press/release VolUp, release Power.

There are various different touchscreen software you can load via fastboot and there is a calibration file in /system/usr/idc, but it isn't clear any of these would help if your screen doesn't work at all.
You can try changing the touchscreen software, worse case, it stays the same:
http://forum.xda-developers.com/showthread.php?t=2428133
Alternatively, you can open up your tablet and check to see if the flex cable for the touchscreen has become dislodged. There are 2 cables that run across the center battery. The one that is reinforced using tape is the one for the touchscreen.
Just did a reset but it didn't work.
I already tried these different firmwares from your link but it didn't make a difference.
I guess the screen is just broken. Or is it possible that the new Subboard is not working with the motherboard and therefore the screen fails?
I opened the back but it looks fine doesn't it? Is the big cable the on for the touchscreen or the orange one?

Yes, that is the cable. You can carefully removing the tape reinforcing the motherboard side of the orange cable and seeing if there is anything preventing a good connection, possibly use compressed air to clear out the connection area. The other end of the orange cable also connects to the touchscreen underneath the usb module so you would need to remove some screws to check that connection.
That's about all I can suggest. It didn't sound like a software issue because your screen completely doesn't work.
Yes I will look at the side where I have to open screws since that is the part they changed. Mabybe they didn't connect the screen.
I also wrote the support already.
Thanks for your help, I will report back.

Hi there
I have also experienced a very similar problem. The charging port on my 2013 Nexus failed to work, I then ordered a replacement part and changed it. It is very straight forward and simple to do for a novice like me.
on replacing the pcb the charging resumed faultlessly but the touchscreen has become unresponsive, i then replaced the old pcb and the screen has resumed functionality, but charging is not working.
The part was replaced by the supplier and it has occurred again, charges fine but the screen is unresponsive. Again i reinstall the old part and hey presto screen is ok.
I am now going to try and replace the actual usb pin itself from the original failed board and see if i can repair myself.
I had also done all the resets and reboots mentioned online.
Not sure if this helps but thought i'd share as its relevant
Many thanks
Is this the n7 2013? If it is how the hell did you get the back off? I tried and was afraid of breaking something.
Sent from my Nexus 7 using xda app-developers app
It's really easy. No tools required. Run your fingernail around the perimeter of the tablet edge between the screen edge and angled plastic. You'll hear the clips releasing as you go. Then carefully work the back off. No glue, just clips. Takes about 1 minute.

Any update on how you solved this ?
I would appreciate if anyone could share the solution for unresponsive touch screen, if it's possible at all. The screen only reacts on the edges, and only to the swipe gestures, not to tapping. But all and all is the same - broken USB, replacement part, unresponsive screen.

I think this is the same issue: http://forum.xda-developers.com/nex...a/usb-io-pcb-touchscreen-calibration-t2939991
Is there nothing to "calibrate" the screen? Asus is supposed to do it for you.
I think the problem is the rev. number of the usb board.
I found this explicative video on youtube, but I can't put the link. Look for "Nexus 7 2013 2nd gen charge port replacement issue"
I have the opposite problem: I changed lcd and digitizer two times, both times touch screen was completely unresponsive. I wonder if there's a software solution for this. I know usb board have different revisions, but what about digitizers? Are all the same for every nexus 2013 model? In this case I have to think touch screen connectors on usb board are broken somehow...

I know this is an old thread, but the problem is replacing a rev 1.3 board with a rev 1.4 board. They are not compatible touch screen wise. I have heard that there is a reset tool that only Asus has that can fix this...

My kid broke the original screen and I replaced it with a cheaper one that worked great until he broke it again
Got a new screen but the touch doesn't work and I can't enter twrp except if I disconnect one of the daughther board connector ribbons (can't remember which one now).
My guess is that the screen is for a different revision board.
Any way to solve the problem?
This is the perfect thread. I have a collection of Frankenstein parts and the problem I've had with 5 or 5 devices (flo) is the sub board. Some work, some don't. I'll try the firmware links and report back.
Has any one found solution for this problem, even my Nexus 7 2013 touch screen has stopped working after I repaired the micro USB port. Actually my tablet was not charging and I figured out that there was some lose contact in the micro USB solder joints, untill then my touch working. I haven't changed any daughter USB board but just resoldered the micro USB port after which my charging has started working and I can even connect a mouse or pendrive through USB OTG cable but the touch screen has stopped working.
