Thin white line across center of screen Fisher PC-32S90
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.

If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.
sounds like you have a vertical sweep problem. Where the fault lies cpuld be the vertical output IC the verticle b+ feed, could be the capacitors in the vertical circuit?? Your gonna need to troubleshoot thr vrtical circuit if your not a tech thin my advise is to take the set to a pro for sn est. Good Luck
your problem is common for sanyo and fisher tv's the B+ feed capacitor is defective and maybe the waveshaper in the cuircuit right next to the IC. Your probably gonna need a service manual to find these caps as if you get one from sams photo facts post the vertical here and I will show you the capacitors to change. Done it a hundred times but I dont remeber the #s. Old age I guess. Good Luck
