My rca t.v. wont stop turning itself on and off.

Main board [system control side circuit] fault. Contact any service technician. Gopakumar Gopalan Google

take the batteries out of the remote and replace them

I have a 2000 model RCA P52923 and I had the same problem occur a couple of days ago. The sound hasn't worked for a couple of years, but the TV is connected to an RCA surround sound to resolve that issue. Most recently, while watching TV, it began to start scanning channels by itself. I shut it off and unplugged it for a couple of days, but each time that I turn it on, it begins to immediately start scanning each channel. Neither the remote, nor the channel buttons on the set are able to stop the scanning, and neither of them will perform any functions, including turning the set on and off.
Any advice would be greatly appreciated.

CHECK FOR COLD SOLDER AT FLY BACK BOARD.

sounds like dust collected on the internal parts which after enough time can cause it to stop working. either have tv repair specialists replace the mother board, or replace tv

You have the closed captioning in the TEXT mode. Turn the closed captioning off and it will go away.

maybe defective speaker or audio output ic or shorted capacitor within audio circuit

This is becoz your Internal Remote control response program chip needs to be replaced! You need it to get repaired at nearest service station. Or it may be due to Your keys pressed continously from remote control. Check both the causes! then decide. It will help you!

You apparently have a high voltage arc. Possibly the anode lead to your picture tube. Also the flyback transformer could be arcing. If you're not experience with tv repair, you need to have a tech check it for you. The circuits operate at very high voltage and if you get into it you can get a possibly fatal electrical shock.
