My parents gave me their tv, they bought it a couple years ago, and it has horizontal squiggly lines that change from the top to the bottom of the tv screen. Sometimes the top stays clear, and sometimes its the bottom. Any ways, I was wondering if it might be an easy fix that involves cleaning the the dusty covered electronic boards, or Am i destined to take it to the panasonic repair guys. If any one has questions, or suggestions, I would love it. I read up the board and the archives but really couldnt find any thing that might help.
