Turn power on, approx. 30 sec later it the power


It varies as to what is actually making the TV shut down. Shorting the connectors on the A.C. plug have nothing to do with it turning back on. Its just the fact you are unpugging it for a few moments.

My Sanyo HT28745 28" HDTV clicks but doesn't turn on


I have had a similar problem with my tv, it has something to do with the power supply.Try unplugging your tv from the AC outlet. While unplugged from the power supply hold down the - volume control and then plug the tv back in while holding down the - volume control. It should bring up the service screen. If the screen turns on and is blank then it may need to be brought in for repairs.

If the screen does turn on, either blank or with the service menu, turn off the tv and unplug it from the power supply again. With it still unplugged hold down the power button on the tv and then replug in the tv. continue to hold down the power button until the tv displays a video signal on screen.

Power problem on a RCA big screen TV


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.

It could be a blown fuse, sometimes when power is restored a power spike occurs this can blow fuses in appliances. Check power to either side of main fuse. Then progressivly check all other minor fuses Cheers Paul

T.V. DO NOT TURN


There could be a problem in the main power supply or perhaps the standby power supply. To me at a guess i would say there is most likely a bad capacitor in the standby power supply or there is a problem in the switch mode power supply. if you have no electronic troubleshooting skills, play it safe and take the set into a repair shop or replace it. Now a days, a 32" TV set can be had for under 200bucks. Good Luck

Turn off 5-6 seconds after I turn on tv


Typical relay power problem on these sets for the relay power. most of the time, its the capacitor in the standby power supply that supplys the main 12 to 15 volts to the relay for the main power supply.. Problem is it is not a repair that can be done or understod by a layman in electronics. its a repair for an experienced tech as a TV set is not a place to be experimenting in.
