Our Panasonic 50" TH 42PX75U

well it sounds like something fried inside the tv. In my experience, this sounds like your y-sustain board went bad. it could be your video board also. considering todays value of the 50" panasonic plasma, it will be cheaper to replace it, unless you are willing to spend around $300 to get it fix at a shop.
good luck

Panasonic TH-42PX75U Blue Screen

This could be a reception problem of the cable transmission or the cable box if used. Are you using cable or SAT box. Tv goes to blue screen if signal is weak automatically.

Arcing noise coming from TV

Clicking, popping noise on certain channels. All connections checked for tightness, and sound is isolated to the TV, not cable box or home theater. What is the cause and fix? Does it involve an inhome service call?
