Vertical lines over LED tv
I moved my 50" 4k SEIKI to her house and it now has vertical lines on display. I did bend a video input connection as I took off coax antenna cable. Looked at that connection on board and it does not seem to be shorting anything.
Should I try to replace that board? Could cable connections have come loose?
There are several versions of this tv. I see all boards listed for sale from one with broken screen, but the one I damaged looks different. Could I just replace all with new (keep same screen)?
Ist dies eine gute Frage?
