Question about RCA 20F420T 20" TV

1 Answer

TV Turns Itself On & OFF with Notepad showing each time

When I plug the set in it will continuously turn itself on & off and every few cycles it will stop cyclin & will show the picture but the notepad is on when it does this & when pushing the notepad to turn it off it will sometimes show only the picture & sometimes it just starts cycling again on & off.
This TV wasn't even 8 months old when it started doing this but Wal-Mart wouldn't honor the return policy on it so I'm stuck now. It wasn't an expensive TV, but it's the principal of the problem and Wal-Mart Not Honoring their Products!!!
I do computer and satellite receiver repair & I feel that this is a Programming problem with the Flash/Eprom chip or somthing of that nature as the capacitors & Circuit board look to be in good shape.

It turns itself on and off repeatedly


Try this:

Unplug the tv let sit for a minute while you replace the batteries in the remote and cover the IR remote sensor on the front of the TV. Cover it with a piece of black tape or a piece of aluminum foil.
Plug the tv back in and turn on.
If it no longer turns on and off by itself then you have IR interference from some other remote operated device in the room.
If it does continue to turn on and off with the IR sensor covered then it is the internal wiring/processors and will need servicing.

Tv turns off by itself


Try unplugging the cord for a few seconds and then plug back in. This happens on one of our TVs. Using this procedure takes care of the problem. It is like something needs to be reset.

Set turns off, resets itself, turns on, repeats .


I think you might have a bad solder joint in the power supply circuit or a bad solder connection in the horizontal drive circuit. I've found a few RCA's that had a poor connection on a little inductor coil in the base circuit of the horizontal output transistor. A drop of solder cured this problem. Stargazer
