A few weeks ago, my G3 screen went black, and it wouldn't shut off without pulling the battery. I pulled the battery, and tried to boot it, but it would show the initial LG splash screen and then go black and not boot any further. Every few attempts the LED will glow, but it still black screens. I have tried a cache wipe, and it black screens on that too. I've also tried a factory reset, but it gets maybe a minute into the process, then black screens again. Any help will be greatly appreciated.
