Your horizontal or vertical chip is failing after they get hot causing your set to loose its high voltage. Whenever one of them fails completely your set will fail to come on. If you are a tech check all the caps even the ceramic ones in the high voltage section before replcacing a chip.

My tv is not working right with picture.


Press the TV button on the remote, make sure the TV is plugged in, check the electrical outlet to make sure it is live if the TV does not turn on. If these actions do not solve the problem, press the Power button on the front of the TV. If the TV turns on, replace the batteries in the remote control and reset it by pressing the number 1 button for 60 seconds. If necessary, reprogram the remote.


Unplug the TV for two minutes, then plug it back in if the buttons on the remote don't work. Make sure the remote is in TV mode.


Change the settings on the sleep timer if the TV turns off unexpectedly. Unplug the TV and wait five minutes before plugging it back in if necessary.

Check your antenna connections and cables if the sound is okay but the picture is poor. If all the connections are good, adjust the sharpness function.

HDRCA 52" model R52WH77, the pic looks like a big U in the middle of the screen and it turns its self on after turning it off. Sound is fine.


A capacitor is building up power and then when there is too much power it discharges turning the tv back on without you hitting the power button. The tv will need to be repaired by a service tech however get a quote and then decide whether it is better to just buy a new tv. LCD's have dropped in price greatly.

RCA L32WD12 32in. HGTV LCD Television


I had the same problem happen this afternoon, so I took it apart, and the source of the problem is the key controller panel (behind the buttons). It's held in place by 2 screws, if you take the case apart, which is literally only 15 or 20 screws, and then loosen the 2 screws holding the key controller panel on, and then use a small screwdriver to space it out from the button caps. Tighten the screws, and put it back together. Just be careful not to let it go too far to the other side, or you'll have a problem with the menu going on and off at random, which is just as annoying.
