I have a 61" JVC AV6100 flat screen TV. It's around 5-6 years old. It was working fine a while ago, then it shut off automatically. I thought it was a timer, but the timer wasn't in effect. When I tried turning it back on, nothing would appear on the screen, however the green light showing power is on though. And there is this humming noise in the back, from what I think is this large yellow cylindrical thing. Once I find my camera I can take a pic of it and put it up on photobucket. So I let it rest for a while, turned it on and it was working fine. About 10 minutes later it turned off again. I opened up the back and whenever it's on, the screen is blank still and the power light is on. In the back, there's a noise that I think is coming from this big yellow cylindrical thing. Not sure what it is or what it does, but I think it's the source of the noise and problem. Now, what I'm reading around places is that it might be a capacitor. But I'm not sure and don't know much.
