Thanks for the reply.

Initially, try unplugging the set from AC power for 30 minutes or so, then plug back in and see if it resets.

If the problem still occurs, then it is most probable that there is a failure on the power supply board inside the TV. Commonly the capacitors on this board will receive a surge and then fail. They can sometimes be visually verified by removing the rear of the set and inspecting them for bulges or leaking fluid at the top or the base of the caps. This is the most common mode of failure for these sets.

Unfortunately there is no sequence of buttons you can press to fix the problem, and the set will require repair. You're covered under the manufacturer's 1 year warranty, so I would contact the vendor and find the closest location to a service center to have the TV repaired.

If you need further assistance, let me know.
