I have a lg ld550. I've had it for about 13 months now and its worked perfectly. Just this morning I turned it on and something really odd happened. After about 3 seconds the screen flashed to black, and then back, and repeated this a couple more times, then just shut off. Every time I turned my tv back on it would do this. I tried again after about 15 minutes and it was fine. However after my tv was off for a couple hours this afternoon, the same thing happened again. Does anyone know what the cause is? I have a two year warranty, but I really don't want to go through the hassle. Also you could say over the past month its gotten a good amount of use, I've been playing the hell out of Skyrim.
