RCA F31672ET No Power only a whining noise when plugged in Please help

I'm checking out an RCA F31672ET for a friend of mine. The TV was working fine untill she left it one night while we out for a few hours. When we returned the tv appeared to be off but there was a whistling/whining noise coming from it. The power button was non responsive so I unplugged it. The sound did not end abruptly but instead faded away within a few seconds. I have some experience repairing video game monitors & chassis & I'm fairly handy with my solder station but I have no expertise whatsoever in trouble shooting. If any of you out there have some idea of what this could be, I would truly appreciated your input. Thanks Vaughn

Most likely you have a bad flyback transformer and shorted horizontal output transistor. The whistling sound that you hear is the power supply telling you that it has a short in one of the circuits it powers. Most likely the circuit mentioned above. Stargazer

I have an RCA F31672ET TV. It was working fine for many years. Then all of the sudden it will not turn on with either the remote or the power button. I thought of using a universal remote to try and turn...

Hi - pretty common problem. Not worth fixing, I'm afraid. It is caused by a defective circuit which became defective with old age. the "EEPROM."

RCA F32650 production May 2003. Was working fine. Turned it on the next day, got no picture and a high pitched whining noise.  Please let me know what I should do to fix it.

If it weren't for the high pitch whining noise. I would say it probably is an internal fuse inside the chasis. It is rated at 1.5 to 2.0 amps. With the whining noise it sounds like a trouble shooting bench
job. Problems occur when a electrical/electronics device is turned on and turned off. Inrush voltage,
when it is turned on, can go up to three times more than normal. This also happens at turn off. Solid state components usually fail at this time. I don't feel that this is a problem that can be fixed in the home.---BBB

it sounds me that it is due to cable wire connection where it is connected is probably might be loose or if you have cable box there is some loose connection.

Acutally for f31665 (problems with screen, kinda)

what about broadcasts? Are you able to view TV stations? If yes, try checking the RCA cables, and also if they are plugged fully into the sockets.
