Hi guys
I just started fixing 4k TV few months ago. so I am still learning a lot
I got this tv from friend complaint is ghosting or horizontal lines on image.
never saw the original symptom but I took the tv back home. the funny part is that after bringing to home, the tv worked fine no issue for 3 weeks.
then it started to show the ghosting white image.
I started using the tape method, but this tv does not have a T con board and it has only 1 ribbon cable from main board to the tv panel.

Hi to all,

Hi forum friends,
A friend bought this working AOC lcd monitor and used it without problem for less than 6 months. Yesterday he brought to me and said it has a horizontal line now and will auto shut off in less than 2 minutes. Btw he had decided to dump it if not repairable.
