There is a thin white line across center of my TV screen. It is a Fisher PC-32S90. It appears to be a connection issue with the video input or a least something in that area on the back of the TV. Maybe something is loose. In past if I wiggled the cable input, the TV would go back to normal, but this easy solution no longer works. I have tried different ways to input a signal, and the same thing happens with all input methods. The sound works fine. Thanks in advance for any help on this.
