[Q] Completely Grey Screen
I was hoping to turn my wife's old epic 4g touch into a cheapcast. So I bought an mhl adapter from monoprice. She hasn't used her phone in a few months so it was completely dead, so I charged it up and booted the phone and the screen was acting really funky with grey lines and such. The problem just seemed to get worse and worse over a ten minute period, and now the screen is just grey with lines sometimes, and completely grey at other times, every once in a while I can see the screen barely through the lines.
Capacitive buttons seem to still work and I can tell the touch screen is still working as I can unlock the phone, but I can't see anything on the screen at all. I did have the MHL adapter hooked up for a few minutes to verify it worked, and it did but thats it.
I seen some other threads about the grey lines being a battery issue, but I have three batteries for the phone and the same issue with all three. Two are cheap batteries and one is the original samsung battery. And I couldn't find any threads about a completely grey screen with a working touch screen.
So is it dead? Would recovery possible fix this? If so how the heck do I get to download mode without being able to see the screen?
This phone is stock unrooted with whatever the latest firmware update from sprint was. Sorry I can't give you more details, it wasn't my phone so I haven't messed with it too much.
