Question Rca Tv

I have a 1996 RCA 46' TV, model # P46720LV. It was turned this morning, and was on for about a minute, then just went off. Trying again this evening, all I can hear is a faint high pitched noise when I try to turn it on, but that's it. It doesn't come on at all. I tried replacing the plug, with another that I had lying around. Same thing, nothing. I know that the outlet works too. Obviously, it's too big to lug anywhere, and I was wondering if this was something that I might be able to remedy. I appreciate the help!

Had a similar problem with a different brand of TV. Problem was in the power relays. Wasnt very expensive, about $150. You need to find someone locally who does in-house service. Hope this helps

Good Morning, LizzyBobio:

Sounds like a classic short in the set's high voltage power supply. The high pitched noise is sound of the horizontal oscillator circuit trying to generate a horizontal deflection to develop the high voltage. The oscillator is running at 7880 Hz which is in the audible range.

When you have a shorted component in the high voltage stage, the set will not produce a picture, obviously, and the set will go into a "protection mode" to turn itself off.

Thanks for all the help. If it's too much, I just may end up with the best looking fish tank on the block.

Good evening, LizzyBobio:

hmmmm! Fish tank? That's unusual. We always made liquor cabinets out of the beasts! LOL!
