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.

Enter download mode and recovery. If you only see part of the screen in both modes, the screen needs to be replaced. If not seen in either mode the GPU on the motherboard is the culprit and needs to be repaired.

LG G2 DISPLAY ko?

Hi, yesterday I had an accident. My phone dropped to concrete floor. I have QW case. Display is not cracked but there are some color lines. I could fix that with light slam but now it is totally KO. When i turn ON display there are some blue lines but after few seconds there is more and more white color. Is there any chance that I could fix that without switching display? Thanks.

Honestly, it is probably done for. Before you throw in the towel, you can try opening up the back and unplugging and replugging in the connections from the screen to the boards. Watch a disassembly/reassembly video on YouTube first!

Good Luck!!!
Same here,unplug & replug connection 'll solve this problem ?
Its probably the connectors. Do check them as an user already suggested.
If the problem still persists, you need to replace it.
BTW may i ask what ROM are you using?
I´m using RR 6.0.1 MM

Nexus 7 touch unresponsive

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

Hello,
After replace the battery of Mi 9T I noticed that the flashlight (torch) is blue. I checked the board and there's no anything out of the place, at least I believe it.
Is there anything that I can do? Does anyone have any tips?

Tiago.

Dear yaro666,
I think you solved the riddle, there's no yellow phosphor materil on it. I compared to another boards on internet.
Do you know where I can find this material or something I can use to replace it?
You can buy smd led or led bulb and try to replace just that, but honestly I never tried.
Led is cheap, so worth a try.
