I have a 20" Panasonic CT-G20G23 that I got close to 6 years ago. Within the past week, I noticed that the bottom left corner of my screen has something going wrong with the color, blues will appear pink or purple and reds appear yellow or green. It only goes about 3 inches high and about 6 or 7 inches wide. Ive heard that speaker magnets tend to do this but there arent any extra speakers right near that area, barring of course the ones in the set, which is below that area. The only electronic devices near it are my playstation 2, which is about 8 or 9 inches below the television and my receiver, but the receiver is to the right of the ps2, not directly below the abnormality. Does anyone know why my television would randomly do this and if there is a way to fix this problem? or does this happen eventually?
