They can give you pricing on the power supply and main circuit boards.
I still don't have the money to fix my problems. The problem went away for a while, then came back for a while, and now seemed to be gone again for the last several days.
But today I powered off, then powered back on a few minutes later, only to hear the sound of some kind of sizzling, which really freaked me out. If I don't have enough money to fix it, I sure as hell don't have the money to replace it. The screen didn't turn on. The standby light, which is usually on even when the screen is off, was out. I was fearing for the worst by now.
I flipped the switch on the back and let it sit for a little over 30 seconds. I flipped it back on, still no standby light. I sat there for a few seconds, and the standby light magically came back on. I then tried powering on again and it worked this time. Screen's been working fine all day since, not even the old problem I was having happened.
I think I figured out what happened earlier though. When I went to go watch TV, no 480i sources would display at all. 480p, 720p, 1080i, and 1080p all worked fine. I think the 480i scaler got fried or something.
At least my cable box has an internal scaler for those channels, so that's not a big deal.
So, for the experts out there, could today's problem be related to the other problems I had been having? Or is my TV simply having a slow and painful death?
