How do I repair a Panasonic TH42PX80U A that has a constant red light on but no picture, sound or display?

Typical problem would be power supply capacitors. You can replace them if you have soldering skills (use same value but 105 degree instead of 85 degree), buy a replacement board, or take it to a repair shop. Try these guys for parts
