.:: HELP Appreciated ::. Universal - WHITE SCREEN Problem...

.:: 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..

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 ..

[Q] Extremely weird screen behaviour.

Hello all! Ive just recently got my Xperia arc, and flashed a nightly build of CM7 on it, number 20. Everything seemed to run smoothly, but just now screen started to behave very weird, it almost seem to have osme kind of "ghostly" second touch.
The upper part of the screen is almost impossible to use, when I try select an app to move it on the screen, by holding finger down, it just flickers for a second and gets deselected. If I manage to select it and drag+hold, it starts spazing out all over the screen, with screens switching between eachother by it self.
The problem is especially noticeable in games, where you usually have a joystick controller in bottom left corner. When using it, I usually trigger the buttons above it in the upper left corner which I am no where near at with my finger.
Is this a ROM issue, or hardware issue? Ive been using the rom for couple of days with no strange to it, and now this happens. Any ideas what the source can be?

ROM failure.

Sorry for bump, but apparently the problem remained. I changed to XDA rom, which too is based on CM7 thou and after a day I stumbled upon same problem of ghotsly second touch on screen.
I cant hold to move apps, cant precisely press a button in game on left side of screen, it then triggers some other button nearby. I do get haptic feedback from long press on a homescreen, but the "add new" menu popups only every few tries Any ideas of what may be causing this? I would really like to avoid the hassle of resetting the phone and sending it back for repairs :/

try stock one or miui.

It sounds a bit like your screen had a bad encounter with water...
Could this be the case?

No, this phone is only few days old.
I think I am noticing a pattern.. screen behaves this way only late evenings, till next morning. I never noticed the issue during the day, but then it was there again for no reason after I left phone for couple of hours (it's past midnight here at the moment). Now when I think back, same was previous two evening, issue only noticeable during late evenings. Could my phone be possessed lol?
It's quite weird issue too. Upper half of the screen seems to have a ghost touch as I said. When trying to add a widget to upper screen, I only get a haptic feedback from long press. When playing games, all buttons on left side (landscape mode) get activated as soon I press one of them. Most weird of all, is that screens works perfectly in app drawer and settings, but not in app/homescreen. I will test how it is again tomorrow and report. If it works just fine again as if nothing happened I will be really puzzled.
Currently on CM7 Xda version, same was for official version. I am considering updating to MIUI, just gotta figure this radio difference stuff, but am becoming sceptic to whether this issue really lies with ROM and not app/settings.

Yep, issue is gone like nothing happened at the morning, this is is haunted ._.

I've figured the cause, it only happens when the phone is plugged in and charging. Beats me why thou, what remains to see now is if it is tied to the kernel or not. Posting it here in case others with similar problem stumble upon the thread.

Are you using the stock charger, i used to face bit similar problem when i used to connect my old HTC USB charger... later i discover the HTC charger was giving only 500mA , where as sony one is rated at 700mA.

Thanks for the tip! Turns out it didn't like my 1000mA charger I am using for all my usb stuff, but the stock on works perfect (it's 850mA).

one v screeen issue

I am facing an issue with the touch screeen on my one v.... scrolling on the touch screen causes inadvertent clicking of app shortcuts ... this happens only occasionally and most of the time the screen works fine.... sometimes the phone goes haywire and likes to start every app available on the screen at the time.... any guesses to what this could be... this problem started about a month after buying the phone

anyone?

If you use a 3rd party cable and/or charger it can cause this error, when plugged in. Other that it is digitizer malfunction probably.

thanks for the reply ,
I dont use any 3rd party accessories..
would a digitizer malfuction cause this problem to appear only occasionally?

Try just touching your stove when phone is acting up with your free hand or the water faucet even.
I'm wondering if you're building up a load of static electricity and causing it yourself inadvertently.
Long shot, but worth knowing an ruling out.

Can static electricity really cause this? I tried what you suggested but it did not help when the phone was acting up.

Twas a long shot that it might be building a surface charge on the phone, sorry it didn't help.

It can, but really unlikeley. Stacic charge discharges quite quicly, so it will be a second for the phone to recover from it.
The most possible problem I think will be at the digitizer chip. It is earthed, an protected by a farraday-cage (i think at least), but if the galvan connection is out (means it is not soldered in place good), the phones electro-magnetic field can cause malfunction. I'm not in posession of a detailed blueprint so I don't know how it is earthed. If the phone is stock as it can be (so not unlocked) try the service.
I happened to have this error in my former Samsung Galaxy Spica, but it was a software error first, then the digitizer itself gave in, but changed it, it works even now.

Touchscreen Input Issues

Hey, had my Z1 Compact for a week now and I've noticed a very annoying issue where sometimes when using the touchscreen to drag, say for predicitive text, the drag line will stop and then restart after missing some of the screen. This is results in having to retype a lot of text, and also requires multiple attempts to unlock the phone with a pattern.
I've replicated this in Settings --> About phone --> Diagnostics --> Test Device --> Touchscreen.
Basically if I keep trying to draw a 4 on screen for example, maybe 2/10 times it will miss part of the drawing. This isn't always the same part, so I dont think it's a dead section of screen.
Anyone else had this problem? Any solutions? BTW I've not put any screen protectors on yet, not even the one in the box as it looks like thats just a replacement for the factory fitted one.
Cheers

Many users are having this problem including me. I have faced this issue just once so I am waiting to get the issue again before going to service centre.. This problem is common in micromax and sony devices.. And from my previous experience I can clearly tell that this is hardware problem.. Dont know how some people told it software issue.. Day by day this problem will increase and soon the screen will be unusable.. I can say that charger may have some relation with this because in my previous micromax the problem started while charger is plugged in and after some days the problem began without charger..

Good point about charging. I have experienced this with previous phones whilst plugged into a cheap charger. I put it down to the charger not being powerful enough. In the instance I mention above, the battery is fully charged and not plugged into the charger. Plus the only charger I've used so far with it was the official one in the box.

You might wanna use some other charger I haven't actually faced this problem more tab once cause I've used the original charger only a few times N it's in best interest to use a lower output rated charger might take longer, but it's best for the phone N it's battery

I dont think the charger is the issue as it happens when it's not connected to the charger and it's been rebooted since. This is a different issue to what I talked about with previous phones and cheap charges whilst actually charging.
I've searched the net and it looks like a fairly common issue with some Z1s and Z1 Compacts:

http://talk.sonymobile.com/t5/Xperia-Z1-Compact/Touchscreen-loosing-touch-issue/td-p/580111
It sounds like the Z1C can come with 1 of 2 different screens, and only one of them suffers from this problem. Also, if you dont use swipe unlock or swype text then you probably wouldnt have noticed it anyway.
Reading all the comments, it's hoped that a firmware update will fix this, but no confirmation from Sony if they will do this and when.
The place where I got my phone from has offered to replace it so I'll take my chance with another one and hope it's from a different batch that doesnt suffer this! Awesome phone, but having swipe unlock and swype text nearly unusable is a major issue.

Siftware update cant fix hardware defect.. And this problem is not only common in xperia devices but also in micromax devices.. I dont know how can people say a softwarw update can fix this.. And I can bet this problem will get worse day by day.. I have already faced same issue in a micromax canvas 3D and the screen got unusable within 3 months..

For those which dont have this problem, have you got a screenprotector on it? If so, is it the one out the box or a third party one?
I haven't put a screen protector on mine, just wondering if that would somehow help.

Try activating Pointer Location in Developer Options
I have tried activating Pointer Location in Developer Options since I also sense some sort of problem with screen input like touch being jumpy at times.
When swiping with two fingers, everything seems fine as long as they are far enough. If my two fingers are very close and swipe the screen most of the time, one finger's Pointer Location would break at some point and continue. Can anyone confirm if this is normal? Would like to have a screenshot of this but Pointer track would be lost.
I have an AUO screen by the way, Thanks guys!

So I've had a little test tonight.
Tried finding what screen type I have but it complained about permissions when trying to access the file, it's been mentioned on another thread that access to this was locked on some update. So no idea which panel I have.
Anyway, used PC Companion to Repair the Phone and go back to factory settings. Build number showing as 14.3.A.0.757. Android version 4.4.2.
Ran an update but it says it's already the latest.
With a naked screen (except for the factory fitted anti-shatter film) ran through the touchscreen diagnostic multiple times, and nearly every other test I had a missing part of a swipe.
I put the temporary protective film back on (which came on it already with the little pull tab on the corner, the one that's not fully see-through) and ran through the diagnostic test, and this time I couldn't get a swipe to miss. They were all good!
Took the temporary film off, tried again and it missed bits again. Temporary film back on, re-tests and no missing bits. This may just be a crazy coincidence, but it looks like having a screen protector on fixes this. If you have this problem, give it a try. If it's still problematic, maybe try another screen protector or if you still have that temporary one try the tests a few times with that on.

I've had touchscreen issues for some time now, even with a screen protector on. But since I flashed doomlord's kernel some days ago, everything is fine. I don't know if there are even changes compared to the original kernel, but for me, it worked. Swiping this posting would have been impossible before.

[Q] Touchscreen behaves erratically when charging

Hey All
Today I picked up an HTC One M8.
Have set it up and only had it up and running for a few hours.
I plugged it in to charge using the charger that came with it and noticed that the screen would become erratic. Phantom touches would register making it very hard to use. Have tried it in different sockets but the issue remains.
I have tried a spare charger that I have in the house and the issue is not present.I know the HTC charger is a little different in that it supports some kind of quick charger, so its not really a like for like swap I guess.
Is there a chance that the included charger is faulty? Or could the phone be at fault?
I really don't want to have to return it but will it it looks like its the phone that has an issue.
Thanks

Well, at this point its hard to guess from here. Can you upload some snaps/videos ? It would be helpful for anyone who visits the thread. It doesn't take much time either. :good:

Is it a brand new phone? if not I think the digitizer is going bad.

Yeah it's brand new. Phone is fine off charge and when using other charges. It's just the stock charger tat seems to cause issues.

Do you have a case on your phone? I have a UAG case and the charger sometimes doesn't fully click leading to that behaviour. Without the case there is no problem using the phone while charging.

Maybe the stock charger is faulty. Probably the wires has lost continuity.

I have the same issue with a unofficial charger (2.0A).
No issue with original charger (1.5A)

You are not alone
I also have a HTC One M8 with the same problem!
I have to disconnect the USB cable so that I can use the phone correctly without 'phantom touches' activating things I didn't want.
A classic example is pressing the back button will more often than not take me to google now. It's not supposed to do that. It only ever does this when charging.
Also when using any app the phantom touches will activate things I didn't want it to. Some apps will indicate which button you clicked and this is the perfect way to see this problem in action, because buttons will be clicking that you didn't even touch.
It's almost like the touch screen becomes ridiculously sensitive and even just a touch of breeze from a fan can activate a phantom touch.
My phone has done this since brand new. I've had the phone for around 3 months now. There was a software update since I had the phone and it didn't fix the problem.
It does this for me with the stock USB cable, samsung USB cable, generic USB cable, charging from AC/PC/Car it doesn't matter.
It even has the problem when the battery is at 100% with the cable connected.
The only way to accurately use the phone is to unplug the cable!

Erratic Touch on Verizon HTC One M8
This has been driving me mad.
Got Verizon Variant Red HTC One M8 near the beginning of August.
I bought a spigen clear case, a longer usb cable, and a 2AMP charger to use at work. I was chewing through the battery while playing Clash of Clans on it at work.
I pretty much always turn on visual feedback for touch on my smartphone now and noticed sometimes while playing Clash I would see multiple touches go in a horizontal line across my screen (if you do not know you play clash of clans in a horizontal position so technically the lines would run vertically down the phone)
I also have a tempered glass screen on my phone so I figured it was some kind of freak nuance with the case pushing the glass or something.
Bought a UAG Case for my phone, few days later I notice the same behavior, bought cases have a small "lip" to protect the screen if you drop the phone face down, I again figured this must be the culprit and bought a new case.
Barely there Clear case by casemate, I have had the case for 3 days and today is my first day at work since, immediately upon connecting my charger I noticed the erratic touch behavior.
At this point I realized it was never the case, it has to be something with charging in general or the specific charger I am using.
Anyone got any clue what is actually causing this issue?

Hi guys, any news?
I'm experiencing the same issue and this is driving me mad.
Experiencing this with different chargers. My cover is a Spigen Ultra Hybrid Metal Slate...if I put it off, theres no problem while charging
Greetings from Switzerland

Hi guys,
I have faced the issue as well. In my case, if I charge the phone using the dot view case then the touchscreen behaves wrongly. However, if I charge the phone with no case at all it works fine.
Anyway after I flashed the latest firmware (.401.6) the problem is gone. What firmware do you have?
Cheers.

Hi Guys,
For anyone interested, I have just noticed that it happened depending on the charger also.
Cheers.

I have the same problem
Using htc one m8 developer edition 4.4.2. This issue comes with every charger. With or without case or screen protection.

Yep, I've noticed this issue as well. Any solution?

Yeah it's brand new. Phone is fine off charge and when using other charges. It's just the stock charger tat seems to cause issues.

If it's brand new, take it back for a replacement. The sooner the better because the longer you wait, the more they may think it is user caused.

I just got my phone replaced due to bad mic. I had a brand new one on release day and now I got a refurb both suffered the same issues. It's not always that it does it but it certainly pisses you off. Same symptoms as the op describes, I have yet to find a permanent solution.

This is so super irritating. I feel you. I just found out though that it occurs when I have my case on.. So whenever i use the phone when I'm charging I have to pull the case off. It really doesn't make any sense lol but this is my workaround for this bug.

I also have the same problem
It seems to occur when the phone is close to full charge. Every app goes crazy. When I unplug the charger it returns to normal.

I have the same issue with mine; I found a website which said to do the following:
Using two fingers swipe down on the status bar then touch the gear icon > Display & Gestures > G-Sensor calibration
Place your phone on a flat surface then touch Calibrate.
After the calibration process has finished tap Ok.
You should also calibrate the finger touch on your screen to deal with the keyboard issue.
Open “Settings” and go to “Language and Keyboard”
Tap “HTC Sense Input”
Tap “Advanced”
Tap “Calibration tool” (Calibrate your screen for a better touch experience)
Now you are asked to type the given sentence
One done, Calibration Complete message appears
Hit “Reset Calibration” to reset screen to factory default

It's still present, but it hasn't been as bad - I turned on the visual feedback in the developers settings, and you can watch the cursor fly all about the screen like it's possessed!

Same issue here, on the latest software. This is my second m8 with the same issues.
