Vertical Lines, TCon Replaced, Still having the same problem, Whats wr
Sharp Roku TV LC-55LB481U. The TV was working fine. My wife turned the TV last Thursday and it turned on with these vertical lines. There was no problem with the TV before.
I opened the TV, I checked all the board, I saw no burns on cables or anything bad. I reseated all cables to no avail.
I replaced TCon, but TV still does the same thing. Can it be a bad main board or something else like the power supply or the actual panel?
When the scene is dark, the lines kind of disappears but as soon there is white info on screen lines came back again.
Hoping you guys let me know were to start with it.
This post is my tv, with photos.
Thanks in advance for any support!
