[Q] Working device, dead screen
A friend recently sent me her "retired" Galaxy Note II. She replaced it because at some point the screen stopped turning on altogether, but she still wanted me to see if I can salvage it somehow. I've tried, with no luck, and searches on the topic don't seem to suggest any solutions other than the fact that it may be a hardware issue. While I can accept this possibility, I'm really hoping that it is not the case because at this point I don't think it would be worth investing the time and money to buy the parts, learn how to replace them, and attempt it. If anyone has any ideas I'd be very grateful. Here are the symptoms:
- The display NEVER turns on. It is in a constant state of pitch black.
- The sounds are working fine. When I get an email, for example, it notifies me.
- The hardware button works
- The software buttons do not work
- Upon connecting the device to a monitor, keyboard and mouse, the monitor works, however the keyboard and mouse do not. (I use the same monitor, keyboard and mouse with my Galaxy S4 and they all work fine.)
- Touch interaction with the screen is working properly. Using the monitor, I am able to use the device, but it is very tricky, as it is simply a matter of trial and error. I tap on a black screen and have to look on the monitor to see if I hit my target.
The device is on the stock TouchWiz that came with it, and is not rooted. Since I am pretty sure that doing any mods without a working display would be more difficult than I could tolerate, I opted to take an OTA instead, despite the fact that it may make rooting and flashing ROM's impossible in the future. I hope I didn't screw myself by doing that but I had to make an executive decision. Here is what I've tried so far:
- Factory reset
- Update to the latest software (Android 4.3)
- Pulled battery, held power button for 10 seconds while battery was out, replaced battery and powered device on.
I'd greatly appreciate any suggestions. Ideally, here is what I'd like to happen: get the display to turn on and restore functionality to the software buttons. This may not be possible without replacing some hardware components, which as I mentioned is not an option, but if it is I'd really like to give it a shot. Thanks in advance for any suggestions.
