RCA Big Screen - Power turns on but then it powers off intermittently

Check the power supply for electrolytic capacitors with the tops swollen. If you find these (should be either 2 or 4) replace them.

possible bad power board

Try unplugging it for about 30-60 seconds, then plug it back in and before you turn it on, make sure there is a good video source going to the TV either from Satellite/Cable or a DVD player or something.

If this doesn't work, try unplugging it a bit longer and then plug it back in and try again. If it still does not work, you may have to take it in and get it serviced.

Usually when devices power themselves off like that, there's something wrong...

I hope this helps :) Good luck!

if you heard a hissing or like static sound your board probably has a hole in it now. the board on the left side with the flyback fransformer. the hole is from where a prong has come loose an is arking over an it burns the board the ark is the sound you heard.

Definitely try a power drain:

1. Unplug the product's power cable so that the device is not grounded to the house. Do not simply turn off the power-bar if one is in use.
2. Press and hold in the products power button for 1 minute to release the retained electricity from the capacitors and circuit board.
3. Plug the product back into the wall outlet rather than a power-bar to rule it out of contributing to the problem and turn the device back on.
If this doesn't help, the TV will likely require service for the mainboard. Since you are hearing a beep, the power supply must be trying to turn turn on but if the mainboard is shot, this is usually the outcome, good luck.

tv worked great, turned it off one day and back on the next and the on light would not come on nor would the tv work, rear projection 52 inch rca

Even with the tv turned off, the power supply is still active.It's supplying voltages to the microcontroler, that's why each time you press the power button on remote the tv respond by turning on. First check the power cord to be well connected in the power-bar and if it's ok...well the power supply is defective and due to the high risk of electric shock i suggest you to call a technicien.
P.S. I respond here because I don't know why our chat session got disconected.

NO audio and no picture .... no power to on - off button. Checked outlet and it is good .... cable connection good - checked with another tv....
