I have a problem with Nexus 7 (2012). After some time of using N7, the screen image suddenly "collapse" into one horizontal thin white line and it turns into blank screen. It happens within seconds. Press the power button, it came back with lock screen displayed. Attempts to unlock screen will turns it into blank screen. Press the power button again, the lock screen came back. Unlock it, it turns into blank screen. No matter what I do, it seems to trapped in a loop.

One thing for sure, the OS did not crash but it seems like hardware problem, perhaps display. Does anyone have this problem before and is there anyway to diy fix it ?

I hardly use this tablet, mostly use for internet access and reading.
