Question about Panasonic TH-42PX500U 42 in. Plasma Television
If the lines are 2 or more inches wide and stationary then this could mean a bad buffer board, when ever the lines are thin less then one inches wide then this indicates a bad panel. Now if the lines are moving then its possible that you are getting a 60 cycle humm in one of your inputs. Or the power supply is causing the problem, to be honest the most common failure in panasonic plasmas is the power supply. I would turn on one source at a time to see which source is causing the problem. One of the sources may have a defective power supply and sending the hum into the unit.
