check the TV power cord first., try to plug any other appliances on the same surge protector or outlet, like electric fan, electric iron., see if's work., if it does, probably the power supply of your TV is in trouble.
Relative to Olevia TV Power Supply Problems Solution provided by: kb8tez Matt, the problem he had was Electrolytic Capacitor CS21. Upon careful examination of the Power Supply Circuit Board I find that CS21 is in parallel with CS22. Simply replacing BOTH Capacitors makes for a more permanent fix. Radio Shack P/N 272-1032 1000UF 35V Capacitors @ $1.59 each plus tax makes a very inexpensive repair. Apparently the same power supply circuit board is common to many different Olevia Models.

I have a 47 a 32 and a 37 inch olevia tv. Just bought the 37 because i havent had any probs with the others. Well recently i moved my 47 inch and had it plugged into an outlet that had a one of those one into three strips plugged into the outlet and my tv kept shutting off. So i plugged it into another outlet and it worked fine so do try another outlet.
I have a 32'' olevia 232v hdtv. I had a similar problem where the tv stays on less and less as you use it longer and it gets warmer. I called customer service and they explained that its most likely a problem with it is doesnt have enough power to run well. They said turn the TV off, then hit the master turn off switch in the lower back of the tv, then unplug everything from the TV, then unplug everything from the wall. Then after 3 or 4 hours, plug all back in and try again. Then they said if i still have a problem, call customer service at 1 866 9 olevia
