Title says it all. My TV was working fine yesterday night and when I turned it on this afternoon, it wouldn't display anything. I toyed around a bit and did a reset/unplug a few times. The funny thing is the back light(sound too) still works and I had to replace a Samsung a few months back because the thing wouldn't even start up at all. It didn't even have sound. If anyone has some suggestions, ideas go ahead and shoot! My TV is still under warranty so I won't open it up. If the worse comes, I'll just go bring it back to Costco in a few weeks. Thanks!
