Screen has vertical lines
I just bought a 60" Samsung TV (model UN60JS8000F) off Facebook Marketplace. The seller said it was working perfectly fine until they had a lightning storm one night. After that, some vertical lines appeared in the display.
He said the area in which he lives is notorious for power surges. As the TV still has power and sound, I suspect the TCON board took a hit. I've been watching a lot of YouTube TV repair videos lately and several times I've seen people "work around" the issue by putting tape over some of the pinouts on the TCON's ribbon cable.
Before I try anything else I'm going to try power resetting the TV and also a factory reset. However, if neither of these steps solve the issue I'd like to try the tape method. Is there any way to definitively identify which pinouts are malfunctioning (if that is indeed where the fault lies)? More often than not, it seems like the techs just used trial and error.
Also, if anyone with this particular model has experienced the same issue and can provide some advice/insight as to what I can try to fix the issue that would be greatly appreciated!
