TV will not turn on. Will not turn on with remote also will not turn on when pressing power button on side. Red power light is on when plugged in. When I unplug the TV I hear a "pop" coming from the speakers. A week before, I turned on TV and picture was distorted, TV would not turn off with remote or by power button on side, so I turned off power at power strip and then turned power strip back on and TV worked great till today when it would not turn on. Any ideas?
