If your plasma HDTV
has burn-in -- a permanent image on the screen that won't fade -- all is not lost. Unplug your video source, turn on the TV so that "snow" (or fuzz) appears, leave it on for 15 minutes, and then plug in your video source to see if the burn-in is fixed. If your screen automatically goes black (won't show snow), plug your plasma into your PC. There, go to JScreenFix.com
for a program that can help.
