I have a Mitsubishi Model CS 32507. Great TV until last night when my son was trying to hook up a new gaming system. He plugged one power strip into another and the TV now does not stay on. Push the power button and the set lights up for a few seconds and then shuts off. Tried unplugging set from wall for a few hours (same problem). I have the set on the table with the rear cover off. I need your help. Thank you. Really not in a position to buy a new TV at this time. Please help if possible.
