HELP!! Nvidia Shield Portable touch screen non-responsive - Shield Q&A

I have an OG Nvidia Shield Portable with a cracked screen. The digitizer wasn't working after the screen was cracked but that was no biggie seeing how the device could still be managed using the analog sticks and buttons. I encountered a bug with the device so I decided to do a factory reset and, unfortunately, I'm now stuck on the start up screen on the device (I'd forgotten that the device requires the touch screen during the initial set up prompt). The device is on stock, so still on Lollipop, and I can't think of any way to get past the initial setup screen. Does anyone know if a usb mouse would register on the setup screen if I were to connect using a usb otg cable? I have some reservations about that method considering that the analog stick serves in a similar capacity when the device is fully boot. Any help or suggestions would be greatly appreciated.

Broke my G2X screen/lcd/digitizer

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.

Tablet doesn't turn on, jut a BAD flickering screen

Hi everyone, my asus tablet doesn't want to turn on anymore :crying: as you can see in this video the screen is flickering when I move it or press the tablet. it seems like a Hardware issue, I have found nothing in tubes about how to fix it.
When the tablet is booting I can see the logo animation but if move the tablet it just crash and stop booting
Can someone help me or give me some tips to repair it please
It has ICS installed
If you leave it completely still will it boot? did anything cause the issue e.g dropped it, splilled liquid on it, software update etc. If its not booting it would suggest hardware damage (as opposed to a loose connection).
Try connecting it via hdmi and see if the issue continues on a external screen if so you have hardware problems.

Being completely still doesn't work neither :/ it started to crash when the tablet was slightly shaked and sometimes when the keyboard was slide out
Thanks for the HDMI tip, I 'll try and let you know!
Thanks!!
Look for a tutorial to replace the screen, but just reseat the cable, don't actually replace it... unless you're sure the screen is the problem. Many issues were solved by simply disconnecting and reconnecting the ribbon cable.

[Q] White screen of death?

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.

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.

[Q] Screen black, mini-HDMI connection to TV fine

The LCD screen of my Xoom MZ604 is not working as it should. Basically, it is dead, there is nothing to see, its black. But if I connect using the mini-HDMI to the TV I can see everything and I can even move around the menus by tapping the the tablets' black screen in the appropriate places.
Im assuming this is a hardware fault and that I need a new LCD screen (ive already tested connecting plugs). Can someone confirm this.

Touch screen no longer responsive

My wife had her portable for 13 months and the touchscreen decides to not work. I did a factory data reset and nothing. Everything else works fine. It's not ever been dropped. The screen just doesn't respond to touches. The thumbstick works though for the mouse and the trigger works for clicking. The device has never been rooted.
I was told by Nvidia to flash the recovery image. So I try this, and man it was a pain in the ass because I've never done this before and the bootloader screen had the white screen of death described in another thread. So for me to flash the recovery image, I had to watch a video of someone doing it and then blindly follow the inputs and mimic them on my blank white screen.
Well I finally got it flashed and still no dice. From what I have been reading the flex cable on the LCD screen is the issue. Because when I power it on, if I don't have it flipped all the way open, I will have the white screen of death.
Anyone know where I can have this repaired? I live in Cincinnati OH. Also I have another portable myself and I know this is going to eventually happen to it as well :-/
