Question about Panasonic TH-42PD50U 42 in. Plasma EDTV
If it's just interference, it's being caused by something electrical in the home. If you have actual lines that never go away no matter what, that sounds like a repair issue. Call Panasonic customer service, and they will advise you to try a few troubleshooting ideas.

The problem may be due to 60hz (cps) power line interference making its
way into the TV either through the cables that are connected to the TV
or through the AC power wire. A good test is to unhook everything and
connect a VCR to the TV and play a movie to see how the TV screen
looks. If the TV screen doesn't show the lines when playing a movie,
the problem is coming into the TV from one of the cables. Try hooking
up one item at a time until the noise bars show up, when they do that
cable or device is the cause of the noise bars.

I have dual AOC i2553ph monitors. One day I came into work and notice one of them had a single vertical white line moving slowly back and forth across the screen that looked like a scan or radar function. I reset the monitor from the OSD and all is well again. Use "Extra > reset" from the OSD on AOC monitors.
