Hi, I've never fixed a TV before, but our old 25 inch Panasonic tube TV broke down on me. The audio works fine, but the video does not. The video is basically a thin white line that runs horizontal across the middle of the screen. Normally I would just trash the TV and throw it out, but I am currently unemployed and wouldn't mind trying to fix it since I have the extra time. Does anyone know what is wrong? How do I fix it? The model number is CT-25G5B It was manufactured in September of 2000 Thanks so much!
