so rarely the tv works just fine with picture and all but usually the tv starts and boots and the backlight works but i have no picture whatsoever. I can choose between channels and navigate the menu and i can hear sounds so it works otherwise but no picture, only backlight. and when it works and shows picture it doesn't stop working or anything, only if i shut it down and try to start it again then it does it again, and i have to try to start and close it multiple times until it works again. i dont know if it is a software or hardware issue so i dont know where to start looking. help!
