Re: power cutting off and then back on

Most likly a poor or cold solder connection. it could also be a problem in the sweep regulation circuit. Im telling you the longer you wait to have it fixed , its going to cost you more in the future as it will make other parts go bad, with all the surging thatsd going on when it turns on and off.

It wont stay on it cuts itself off and on the power button has t

This seems to be a problem in the Power Supply I would think. Either that or a fault that is overloading the PSU.
This means a trip to the repair shop.
Make sure ya get a firm "Quote" for tha fix before proceeding.

My tv will not turn on the power light comes on

After the power surge , the TV went on protect mode.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.

If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.

If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur after power surge on a rear projection are a blown capacitor on power board, a component on ballast board has blown, or a fault on Digital board had occurred.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

My RCA D52W20 will not stay on

Clicking sound is power relay engaging. If all systems are not functioning properly, unit will shut down to prevent further damage and/or fire hazard
