Nexus 7 touch unresponsive - Nexus 7 Q&A, Help & Troubleshooting

I have been using this device for more than 5 yrs. Recently screen rotation was not working so I tried to repair it by myself after watching some videos and forums. It was an easy process but due to my curiosity I dug into the hardware some more. During the process I mistakenly broke a piece from ZIF connector which was connected to the display. I don't know whether this could do anything to the touch. Now the touch becomes unresponsive. I am also thinking that the digitiser could be faulty but not ready to invest in a new one without knowing the real reason. Why this connector is for. Could this be the culprit? If so do I need to change the daughterboard? You can see the picture

Broken touch panel, help?

So some things happened and my Nexus 7's touch screen got junked.
I've sent the device to ASUS support hoping they would fix it at reasonable price...
I was wrong. They want to charge me almost 75% of the damn price for an LCD change.

This is 210 USD. Any leads on cheaper ways to fix the damn display?
Get a faulty unit from somewhere like Ebay/Craiglist, but make sure the fault aint the screen.
Then take the screen off the faulty one, and replace it onto yours?

[Q] Screen Glitch Problem

Has anyone encountered this before.
It happens or is most visible on dark areas of the screen and gives off a twinkling effect when scrolling. I have tried different Roms, Kernels and resorting to stock but nothing seems to work. Any help would be appreciated.

wow. thats strange. if it was a physical defect (as in the LCD is damaged) then it wouldnt translate over to the screenshot. so it must be software related...but youve changed roms....this hurts my head a little bit. can you RMA it?
oh wow, that reminds me of what would happen when i overclocked my video card too high on my old computer. i would definitely say thats a hardware malfunction... a legitimate RMA

Photo Opinion: Is this logic board or LCD failure?

This G2x suffered fall damage and now the image is heavily distorted. There is no visible signs of damage to the LCD.
It is also experiencing strange "burn-in" effects. E.g. the time on the lock screen remains faintly visible after unlocking and switching apps.
I dont want to purchase a new LCD if its the logic board.
I could really use an opinion from the XDA community wisdom! :fingers-crossed:
The crack is the Digitizer (broken after LCD issues arose)

Sorry, it looks like your screen died.
If you can't get it repaired or swapped under warranty, take it apart and try reseating the display connector.
I don't really think that that's the problem, but it's worth a try.
Replacement screens on the market cost about what a discount Nook costs.

Broken digitizer/Changing the display size

Hi,
recently my digitizer broke, and its not registering touch in the top portion of the display (about 15% of the screen). Since the only way to get it to work is to buy a new digitizer/display assembly which is too expensive for me, I want to the shrink the displaysize so the screen only shows on the lower part of the display where the digitizer works normally. So my question is, is there a way to do so?
Tldr:
Basically i want to change the display from 768x1280 to something like 768x1100. (So the top portion is blank)
Thanks in advance!
