I am replacing the digitizer for a cracked display issue. The tablet worked with the cracked screen.
New digitizer arrived and i roughed everything together to see that the new digitizer works. It does, so i go for full reassembly.
I have the new digitizer connected, white lines barely visible under the connector edge. The LCD is also connected up to the line. When I power on the device now, I get the short vibration and the LCD has a backlit black screen.
Tried booting into recovery using volume button, no joy. Long pressed the power button and I get 2 vibrations like it is doing a reboot, still no display.
Let it sit fora few minutes and press the reset in the tiny hole. Still no joy.
What can I do now?

Does anyone have a TF700 with a busted screen? Perhaps we could work together on this. I now have a new digitizer and a digitizer+LCD. I just need a motherboard or another working tablet to see if my motherboard is defective. I might have shorted something on this one.

Hey,
I accidently dropped my phone in water a couple of days ago. The backlight doesnt work. Under a really bright light i can see the lock screen and it still functions. Is it possible to replace just the backlight? or what should i do? I dont believe this would be covered from motorola and I live in canada got the phone shipped from the states.
Any advice would be appreciated.
Thanks,
James
I'm guessing you might need a new screen/display. Perhaps do a search and find a repair place you can ship it and get an estimate? I know HTC offers such repairs dirctly (ship the phone, they call you with an estimate). I'd bet Moto does as well if you're not comfortable with 3rd party repair.

I have the same problem right now except mine was not dropped in water. In a bright light I can see the lockscreen and also could see the emergency dialer tonight but the keyboard was not reacting on certain buttons either. One screen said to unlock enter your gmail account info,I tried to enter my name and the period symbol(.) was not working for me. I'm thinking maybe the LCD screen needs replaced or the ribbon cable,IDK. Any help is GREATLY appreciated.
Edit: Essentially I finally got logged into the phone and the keys were working fine,the screen was still dim so I turned the brightness all the way up and turned off automatic backlight. I replaced the LCD screen and digitizer and now the phone is not starting for me. I'm about to replace the Flex Ribbon Cable inside the phone and see if this corrects the problem. Right now i cant get the phone to start up so I'm thinking the ribbon cable is disconnected somewhere because it hooks to the motherboard and the LCD or the motherboard is fried. IDK,I'll let everybody know what happens with this project.

What happen to letting everyone know? Were you ever able to get it going? Was it the flex cable? How did you get the LCD working.
Replaced the flex ribbon cable and it still didnt help anything. Guess its just the phone. I trashed the phone a while ago anyways and am currently running a rooted Droid 4

I run a cell phone repair company and we do quite a few repairs but this in particular HTC One X has us all stumped here. We do realize that there are 3 different versions of the dig/lcd and we have the correct part. But has anyone had problems with trying to replace the HTC One X dig/lcd assembly. It seems that after I put the new part on the lcd is black but the phone is still on. I even went back and put the old screen back on and it is still black. Prior to the repair the lcd worked fine. But just the digitizer was cracked. I have even went as far as changing the motherboard on the phone to a new one and am still having the same issue. Any help would be greatly appreciated!
Have you checked the ribbon length to make sure you do not have a break?

It would seem to me as though it's just as simple as one of the connectors is not plugged in or just not plugged in properly, which is easy to do since one of them is on the underside of the board which I believe is the one for the screen itself.

Exactly. Seems like the only probable answer is that something was broken during teardown - either a cable or connector. Given the size of everything in there, it doesn't take much....
Did you ever find a solution to this?
I'm kind of in the same boat at the moment, BUT there's a silverish lining
In the midst of replacing a screen on my One X. Phone is obviously "on" (despite being in pieces on my desk), but n either the new or old screens will come on when I push the power button.
For a lark, I plugged the phone in, and did an 'adb reboot'
My splash screen comes up on the new screen just fine, as does the Viper Logo and my home screen and everything.... but once it shuts off the power button will NOT re-wake it up. At first I thought "I must have broken the power button" but I also forced a notification to it - which also typically wakes up the screen - and also saw nothing.
EDIT : Cancel that; for some reason the power button didn't work until I had the case back on. Grounding maybe? Either way, working fine now.
Some Ebay product page for a screen replacement said you should first power on the device with the old screen, then take the old screen out while the phone is running and put the new one in.
Maybe you should trie that. I'm not a hardware expert, so do some research before trying this and don't blame me if it doesnt work
That will only work if the screens not working. Op. It's difficult to narrow the issue in your situation. If the flex cables don't work, it's a short which would require much more advanced knowledge to fix.

Has anyone encountered the following issues with their SHIELD?
Mine was working just fine after updating to 4.3 and rooting with CWM. I performed multiple reboots in this configuration, played games, etc. - everything was fine.
I had a pretty busy weekend so didn't touch the SHIELD at all for a few days. When I got back:
When I opened it up, I saw the screen backlight turn on but nothing displayed on the screen. The SHIELD button was glowing green.
I long-pressed the SHIELD button to turn off the device. When I turn it back on, I get a white screen that is dark around the edges (mostly vignetting around the corners). The brightness of the screen here and degree of vignetting seem to change every time I try and turn on the device.
If I enter fastboot mode via the key combo, the same thing happens - white vignetted screen. The device DOES appear to enumerate as a fastboot device on my PC in this configuration.
At one point I figured it might be due to a low battery, so plugged it into the charger. 30 minutes later, when I opened the lid, I actually came up to a launcher screen with 65% battery.
However, after closing the lid and reopening it again - black screen again, with the "white vignette of death" coming back if I reboot.
Has anyone else seen similar behavior? Searching results in no one complaining about a white screen like this, at least not on this device.
Screen of Death
This just happened to me today. Did you find a fix for this problem?

So ive already gotten two shields and they both got the same effect. my guess is the ribbon cable when you open and close the screen, is wearing off? because when i open my shield in a certain way, it works... when i open it at around 100 degrees or open correctly then tilt it forward, the screen tears and slowly shows the white screen. I do admit that i open and close the screen more than i should, but i do it carefully. Ill look over at the ifixit site to see how the cable is connected to the board.
This is what has me worried about buying a shield, the ribbon cable, did you confirmed this was the problem?

I am a tech by trade and bought one of ebay for 40 bucks cuz it would not power up so the guy claimed. After getting it I found the issue was actually the display was not coming on and once it did. Then went out in a few moments. Connect it to HDMI and the unit runs all day of you want to be cabled. ]
So I tore it down and found that the issue is the flex cable. The problem is that the flex cable is part of the LCD and you cannot just replace the cable. Also since the unit is so new there are no sources as of yet to by the LCD from.
So if you have this issue I suggest just holding out till a source of LCD's at hopefully a reasonable price become available.
So it's soldered to the screen and not replacable right?

That is correct.. The flex cable is actually an integral part of the display and even has much of the driver circuitry placed right on it at the LCD. In the business we call it a flex circuit since it is a flexible circuit board and not just a cable.
I pretty much know what you mean.
On my old Archos Gamepad I ripped the flex that connected the left side of the controler to the logic board by accident.
It was a pain in the ass to fix it by soldering seperate wires, I guess it's impossible to do this with the display connection in the Shield.

Might be possible if you used 32 gauge magnet wire. It is enamel coated so it won't short, but it to will break over time.

How are you supposed to flash a factory image when the screen won't let you see what you are doing? When you are in the bootloader screen the HDMI drivers are not loaded yet so not even hooking it to an external monitor will work. You might want to fully read and understand the problem next time before offering advice.:good:
fastboot tells you if you were sucessful or not.
just for relocking the bootloader you have to do some button combinations, you can look up some tutorial videos to see what you have to press.

Even still, it is not a software problem that causes this. I know because if I move my display to a certain angle it will start to work sometimes. A software issue would not cause this. I also have taken my apart since I am a tech and can actually see the traces in the flex cable that have broken..
Any device with a folding display is a bad idea and a failure waiting to happen. Flex cables have a limited number of flex cycles that is even usually published. So the idea of using them in a device that may get heavy use is just dumb.

I agree, they used flex in the Nintendo DS and 3Ds as well, but they don't break that fast.
I find it still better if they have used recular cables like what they use for Laptops.

What you are saying is the EXACT same thing that happened to my SHIELD. I can tell its a hardware problem because when I tilted my screen it would work, and sometimes it wouldn't. Now my SHIELD's display does not even show any signs of picture. HDMI still works, however. Like one of the previous posts said, there is not a screen available for purchase, so my next step is NVIDIA customer support. Maybe if they would sell these screens, I wouldn't even have to have a warranty claim. sigh.
White screen of death?
yes mine too same as
i tried connecting my via HDMI from power cable to large HDMI to plug it works fine on my galaxy tab
thought id be clever try it on nvidia shield never worked sould of bought mini HDMI so now White screen of death
i cant get into recovery or anything i had this on charge for 12 hrs yesterday still no green button on charge only orange .. i too cant find anything on internet to help with this White screen of death situation

This. I'm having a similar issue. My wife's SHIELD has an unresponsive touch screen. So I tried to flash the factory image (It was never rooted to begin with) and I got the white screen issue when in the bootloader screen. I have to keep restarting it to get the screen to show up as normal when the device boots to the home screen. But the bootloader screen is still blank and white. I was able to watch a video and mimick the steps to flash the factory image but that did not fix the issue. It's definitely a hardware issue. I live in Cincinnati OH, anywhere I can go to have this fixed? I have a portable myself and i know this is going to happen to mine soon.
Ready for the long story? I dropped my TF700T and cracked the screen, it still worked just nasty crack spider web big from left lower corner toward right top. Bought dead tablet off eBay for 190.00 total mb seamed to be toast. Removed both screens complete (could not find info on detaching ribbon cables so just tugged to get em out.) Pushed ribbon cable in on good tablet power on just gets a glow. Later found a post that says to lift white tab to disconnect ribbon cables also about the service power switch. I have attached tablet via HDMI to monitor , I get cromi logo for about 3 or 4 min, than goes black. As tablet is 64 GB model. What should my next try be? Are there any tests to isolate problem comments? Just bought another broken screen pad that supposidely works. I know to first verify its operation, cut off service switch, undo cables screen from digitizer, remove digitizer than try in my tablet. Does digitizer have to be attached to touch screen? Does touch screen have to be attached for tablet to boot? All help is greatly apreached. Broken tablet should arrive by Thursday.

I am passing this on from my son who experienced your exact same crisis:
I do recall that the tablet wouldn't boot unless everything was hooked up...I think...you can start swapping component by component to see if one in particular is causing it not to boot. And if it hasn't been tried already I'd reflash the stock ROM to see what happens.

Hi, my asus transformer T300 screen cracked. So I replaced the digitizer with a brand new one. (Correct Model 5158n) Put everything back and all looks ok but the touch screen is not working at all. My tablet comes on and I can see the screen but I unable to touch anything on the screen. I opened the tablet back up and reconnected everything about 5 times but the touch screen still doesn't work. Any Ideas. When I navigate down to the developer options using the keyboard and select show touches, I get a load of white dots flying around the screen. What does this mean? Do I have a faulty digitizer or is there anything else I can try to get the digitizer touch screen to start working.
Many Thanks

No I didnt. do you think that has affected the digitizer ot the touchscreen board? and do you think not toggling the switch would have affected anything else? How do you think I can fix this problem? Would it be worth replacing the touchscreen main board?

There should be a little switch near the power button on the main board! Flip that before disconnecting anything and flip it again when everything is connected again
