Facing TV Problems? Ask a TV Technician.
Please try this:-disconnect all audio/video wires from the tv.-unplug the tv POWER cord.-press and hold the power button on the tv for 20 seconds and release.-plug in only the tv power cord and try to turn on.
If that does not help then unfortunately there is not going to be any easy reset/fix. The Tv has an internal failure and the back panel needs to come off, checks need to be performed, then parts ordered and installed. If that is something you want to attempt then reply back here and I can assist you further (a meter and prior experience is required). If you are unable or unwilling to perform any of these procedures then a repair shop should be consulted, which I can help with also.
Remember that I am here to help you. Please reply back if you need clarification on any of the above.
