My Panasonic Viera,model tc-p46c2
My Panasonic tv, model tc-p46c2, turns on but turns off after 3 seconds. Started 2 days ago. Working fine before this happened. I have tried the fixes mentioned e.g holding the power and volume buttons down on tv and unplugging tv for a while then holding down power/volume buttons down while plugging tv in again. None of this worked.
