try this and see if it makes a difference
open the lamp door look for the blue switch(bottom left i think)
take the loose wire(blue and white) wrap it over the switch to hold it back
and while your back there make sure you dont have a lot of dust blocking the vent on the back cover

I have this same TV and had a similar problem. This may or may not be the same case with yours. The button panel on the front of your TV may be having connection problems. Mine would come on and off by itself. I took the front panel off and cleaned the connection on the button board with a q-tip and a little dab of alcohol. This cleared up the problem of it turning itself on and off.

Look for loose connections in the power supply (plug, socket).
