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.

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.

Hi to all,
A couple of days ago I noticed that when I answered a call the colors of the screen looked bad, and I didn't pay attention to it.
Now my screen has transparent horizontal lines which are pretty visible, kind of like interference you get in computer screens when you take a picture of them.
I would like to mention that I haven't dropped the phone even once.
I'm considering doing a factory resest in hopes that it will solve the problem, but I doubt that it is a software issue.
What do you guys think?
Please advise
Itay
Sounds like a broken screen to me. And definitely like a warrenty case. Restore stock f/w if you have flashed and return it.
Restore the original firmware (if you have flashed the phone) and call the samsung service for the assistance.
the thing is that now I don't see it at all.
It's as if it came and gone.
I disabled my task killer and juice defender, performed a complete titanium backup, in case I want to restore afterwards, and now everything is normal.
It does sound like a hardware issue, but do you think there's a chance it is software related?
I'm asking because I purchased it in europe, and I don't live there, so sending it for repair is something I would rather avoid.
Of course, if it is indeed 100% hardare issue, I have no choice.
That is why I'm asking, to be certain and to see if there are others who experienced this issue.
Your replies are much appreciated
update:
It appeared again -> Did a Factory Reset -> It's still there -> Sending for repair.
Must be a hardware issue.
Thank you for your replies.
I've actually always had slight screen issues with my Galaxy S also. The screen flickers slightly once in a while. I don't know if the radio is actually the cause but it's the kind of thing you might expect from radio interference.
Has anybody else noticed this?

Nope, never seen any flicker. My screen seems to have a defect of it's own though, but I'm not sure if it's worth the effort to send it in, because I imported mine from the UK while I live in South Africa.
When in the sun or under bright light I can see a two vertical lines near the sides and a horizontal line on dark/black colours and when the screen is off. As if those pixels have a grey/brown tint to them. The line is mostly one pixel thick but in places it is two pixels.
They are almost impossible to see unless under sunlight where they are clearly visible where the screen is black.
Does anyone else see this or know anything about it?
Edit: Apparently it's just the motherboard or something visible through the screen and they all have it, so I'm worrying about nothing...
That's interesting...
It used to come and go, but I think now it's here to stay.
It's really annoying and the screen, while usable, is really not a pleasant sight to look at.
I've attached some photos showing the problem.
With a normal screen I would say that it looks that way because that's what you see when you photograph a screen of an electronic device, but the sad thing is that what you see in the picture is exactly what I'm seeing now.
I did a factory reset, so it's in german now.
I heard some Droid X had a similar problem, but didn't know Galaxy S was having it as well.
In any event, can you confirm that after a factory reset, I no longer have root access?
Just making sure so that they don't give me problems with the warranty.
seem like the phone was dropped, and the screen got damaged
the connectors are lose
double posted again....
Really?
That's very weird...
The only time it was "dropped" was from half a meter , it didn't fall directly but partially sideways, it was with a case, and it landed on its back, not on the screen.
I wouldn't even call that a fall.
Unless, someone in my family dropped it without telling me...
Either way, I think there's no escape but to send it to repair.
If you think it's a problem with the connectors, would you try and give it to some local lab to try and fix it or send it to samsung for replacement?
I faced similar problem.
This problem only occurs when I use the phone in 2g mode.
there are occasions whereby the signal bar for 2g is full and when I place the phone near some conductive surfaces the lines becomes very obvious, to the point of irritating.
nit sure if anyone has such problems too
I have same problems with horizontal lines.
I never paid attention if i am on 2g or 3g when it happens. I will now.
Edit: rooted on jm5
-------------
It seems that my phone too has started to do the same thing since last night.
I have called Samsung and am waiting to hear from them now.
I hope this is a thing covered in the warranty.
I have reverted to the local ROM for India and have deleted everything on my device.
Yet it shows lines flickering like you can see on old computer monitors.
Its not as bad as the ones on the attachment above but it is starting to annoy me.
It usually happens when the screen is completely filled with a single color except black.
Eg. When you pull down the notification tray down.
Also I seem to notice that when the wifi is off, it stops.(I dunno maybe a placebo effect)
aditya_t90 ,
I have sent it to Samsung for repair, and they should tell me in the coming days exactly what the problem is and whether it can be fixed under warranty or not.
I will update as soon as I hear from them.
Until then, try to see if it changes when you hold the phone differently, for example if you grip it more firmly or hold it in another way.

When did you send it in and when did they receive it(if you were not there when they got it).
Also how long has it been without your phone?
The samsung service center is shut in my area today.
I will go to them tomorrow and get this sorted out.
Its not like the phone was cheap or anything.
I actually sent it to my uncle in Germany because it was purchased there.
He went to the store where he bought it and the store owner immediately sent it to samsung and said that probably by this Tuesday or Wednesday (so tomorrow or in 2 days) he will get an answer from them and see what's going on.
aditya_90 ,
Just to let you know that Samsung are sending me a new phone to replace the damaged one.
I sent in my phone for repairs and they replaced the LCD module. The problem is now gone.
I suggest that you should do the same while the warranty still holds since it appears to be the LCD that failed somewhat.
Ok, so i'll start of by saying rougly 6 months ago I bought an unlocked T999V with a flashed ROM which was liquidsmooth 4.3 I believe. The phone worked perfectly fine up until a week ago. The phone was dropped off a desk and landed on its screen, nothing was broken so I thought nothing of it. The night afterwards I noticed a few darkish spots when I would look at the phone at night, only if the background was dark though (setting menu for example). The phone was plugged in when I went to turn it on and it wouldn't. Its unresponsive and I am unable to put it into DL or recovery mode. Leading me to believe its hard bricked and will need a jtag fix. But WHY? Why did dropping my phone all of a sudden mess up my screen as well as brick my phone ? Someone please help me out here :crying::crying:

Are you comfortable opening the device? There's a chance the fall didn't necessarily damage anything, but knocked very important cables loose. I would check every cable connection on the motherboard, and check the battery prongs, as they may not be making good contact causing dead battery. Are you getting absolutely no response from the pc when connected?
Anyway, point is, checking the connections is the easiest thing to do- and you might be able to determine if anything else is loose (ie did it land on the power button and now it's stuck? Etc) It's likely something simple- so check that first, then you can move on to other diagnostics.
The Fall damaged Digitizer. Hence the dark spots. As to unresponsiveness, remove battery and then try. If it still does not work then Power button might be stuck or has loose wires.
I don't know I thought dark spots in a dark room on a dark background were norm for this type of screen- I have them too on a brand new led assembly. Google suggests that's normal and not necessarily damage, although it could be if they're appearing under normal lighting conditions. I agree with everything else though
Wonder if s/he got it worked out?

I brought it into a repair shop and was told the EMMC(?) chip was most likely bad and the phone needed a reflow. I put it in my oven and tried the reflow but no luck, I ended up buying a new T999 as I was quite happy with my first one.
Glad you now have a working device
Hey,
Just curious if anyone has had an issues with a Vertical Black Line on there screen,
i notice it mainly with things that are orange or red,
everything else seemed to be fine had the phone a few months,
i sent it in for repair,
but just curious if this is a common thing,
I've never personally heard of that happening, and its definitely not happening on my phone. Did you grab a photo before you sent it back at all? Curious.
Sounds like a hardware issue, such as screen gone bad, or ribbon cable or other connection becoming loose.
The issue of vertical lines on the screen popped up fairly occasionally back in the days when slide or flip-open keyboards were in vogue. The moving joint between the screen and the rest of the phone would sometimes cause the ribbon cable to fray or become loose.
same issue
got it back from repair . same issue said on the slip they flashed software.
issue still there mainly when u look at red images

That's pretty f... up! This is most definitely hardware issue and they should have taken care of it. Problem is always to describe the problem to repair center good enough to make them see it.... Next time you should leave a pic on the phone with which the prob is easily recognizable and make them look at it.
Yes ,
A red background will be on it when its sent back, and nothing elese but the background,
i explained it pretty good to them , but will certainly be sending it back again
got it back ,screen replaced and bezel ,software says official now and not tampered and says relocked its workin great
Yes, like it turned itself off but it did not go off as I was still getting audible email notifications. Tried everything speaking with Google support and then even Asus support who told me to go to their website and fill in an RMA form. This unit is 13 months old-out of warranty. There is nothing on the form relevant to the nexus to fill in so you cannot continue with it. So I am stuck right now and do not know what to do if anything. Any help would be appreciated.

Normally, 3 things can go wrong:
1. The cable is not connected properly. This could be caused by any impact. You take off the back cover and reseat it. It's the amber cable that runs the length of the battery. Be sure to check both ends. The one on the motherboard's end is in plain sight. The other end is hidden beneath the daughter board at the bottom of the tab, so you need to remove it to inspect the connection.
2. The backlight which illuminates the display went out. You can check this by turning the tab on and taking the tab to a dark room and shine a flashlight on the screen. If you can see the icons or the boot page, the back light is bad. The bad news is that you'd have to remove the lcd/touchscreen unit to replace the backlight. 10 times out of 10, when you do this on an original tab, you will break the touchscreen. Since it's glued to the lcd with LOCA (liquid optically clear adhesive), you will have to separate them, fix the backlight, buy a new touchscreen, then reassemble the whole thing. Most people would find it simpler to just buy a new lcd/touchscreen combo. If you're game though, I can give you an lcd back with a working backlight strip.
3. The video circuit on the motherboard went belly up. To test this, you need a micro usb to HDMI adapter like the one here , and a newer lcd TV. If nothing shows on your TV, the GPU is probably dead, in which case the only practical solution is to replace the motherboard since it's impossible to replace the GPU at home.
Good luck.

Did anyone else read this response and want to hit the edit button, and then type in huge letters "Time to buy a new Nexus!"
Thank you for your detailed reply. I checked the cable from the MB at both ends. Seems OK on the connections. I am unable to turn on the tab to check the backlight. That's about as far as I can go with it at this point. I am thinking that this tab is toast and to make matters worse, the abominably bad Asus customer service. I am considering replacing this with a Samsung and be done with it.

Hey, don't lose hope! Samsung is not any better specs or quality-wise (especially the display). If you're gonna butcher the thing anyway, might as well find out. I was gonna suggest to lend you a used lcd for you to test, but I realize people for some reason are extremely wary of gratuitous offers so I won't. But if you value it, try to get a screen with a good lcd but broken digitizer on Ebay. They wouldn't cost more than 15 bucks. Once you can determine it's not the motherboard, we can go from there. I can guide you on the replacement part if you want. I'm just a hobbyist, but I have messed around with this thing enough to tell.
Graph, you are kind to offer. I also have noticed that the glass has a few cracks in it as well. At this point, I can't turn it on. It seems like when I punch the on button in there is extremely little movement if at all. So I don't know if it is still on which I don't this it is or it shut itself off. When it was black screen and on, I was getting my email notifications audibly but since yesterday-none. I am not looking to spend big bucks on these things as essentially all I do mostly is use for reading. I do want to stick with android if I replace this. I know samsung does not have as good resolution but seems to get good reviews from users.
