I read somewhere (I think on these forums, but I can't find the thread right now), that some people had the problem when they dropped their TF, that the display stopped working. I'm having that problem now, no display at all, but other than that, the Transformer is working fine when plugged into HDMI (touch screen still works). What I read was that its possible its a loose cable inside.
Does anyone know what cable it would be? My screen is also now cracked, which is why I'm not sending it to Asus for warranty repaired, because I'm pretty sure they won't repair it with the cracks going across the screen.
I have the tablet apart, and can see most of the cables, and they all look pretty snug. Any suggestions?
I dropped it a few weeks ago and the screen is toast along with the lcd and digitizer. I have it taken apart and I was wondering - what are the chances it will work again? I have debugging enabled and ended up trying to use androidscreencast java program. It will read the internal memory but won't display a screen. Also, the HDMI out occasionally works but it's a little rocky.
My question is this: Is it possible it's fried, or is there a possibility that maybe it is malfunctioning because the digitizer is completely ruined along with the LCD? I have everything still attached including the camera(s).
Right now the screen lights up (though you can't see anything) but my computer won't detect it when plugged in nor will it output HDMI to my TV =(.
Should I spend the money to get a new lcd/digitizer/screen, or should I just give up? I JUST got this phone (no insurance)
How would it be fried if you only dropped it?
As for anything else, for HDMI I have to enable by using the SCREEN, so that might be why you can't use it when connected to your TV.
And for the connection to your computer, mine detects that I have it plugged it, but it doesn't let me transfer files to or from without enabling mass storage, which is again done by touching the SCREEN.
On a side note, I broke the LCD on my Vibrant twice, everything worked fine, just had to replace the screen. Don't know about this phone, but if the phone turns on, then chances are everything is fine. Unless its a software related, such as being bricked.

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.
Well my 3 year old was using my xoom tablet as his Nextbook tablet is being sent out to be repaired(so this is the second one he has broken!). I believe he has dropped it and now we are getting a screen that is flickering and is showing a blue stripe down the left side. The screen pulls up and I am able to swipe around but its very touchie. Not responsive at times. I did a hard reboot(vol up + power) and no luck. I also reset the whole tablet. I've also plugged in the tablet to the tv via hdmi and it works fine using a bluetooth key board. So my question is will replacing the screen make this tablet fully functional again. I don't believe the software has any issues. Thoughts?
thanks for any help!!!!
From what i've read I believe the digitizer will fix the touch screen but with a replacement digitizer is the blue stripe down the side also fixed? the top of the screen seems out of wack also? anyone run across this before. thanks

Yup, once, it has been 6 months since my nephew has touched a tablet without close supervision.
Hi,
My nexus 5 lcd works intermittently. Touch works just fine. Its the display that goes on and off on its own.
The screen remains unlocked and the touch works as well but the display just shuts off. The display works for a bit and works perfectly and then just shuts. A few toggles of the power button and if i get lucky it starts "displaying" for a few more seconds before shutting off.
I can see on off messages in the linux kernel. Unfortunately, the device is in a shop and i cannot post those messages here right now.
From the hardware architecture, I gather that the display bus is not directly connected to the motherboard/SoC. It runs through the usb flex and then connects to the SoC.
Any ideas what hardware component can be at fault here? The display panel itself? The usb flex or the motherboard ?
Its an old phone. I would like it if some one with hardware expertise could share some pointers here and If anybody faced any similar issues. I am ruling out software problems as I rooted it one day and am fairly comfortable with Linux based OSes.
I am also wondering what roles the usb flex plays and if that could be at fault here.
P.S: I am not sure if this makes any sense, but the more I keep the phone off, the more duration the display remains on "in the first wakeup", a few minutes later it becomes intermittent again.
oh and everything else over usb runs just fine. USB data transfers/ charging. Is the display powered directly by the SoC usb flex plays no role ?
