Hi guys

then it started to show the ghosting white image.

Hi to all,
I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.

Hi guys!
I'm new to TV repair and just started looking into troubleshooting guides and other online info.
Right now I have a Chinese make with LG display that is faulty. If I am not wrong I see two different problems here below.
1. There is a line(white/multicolored) at the very top of the display that shows thinner sometimes and slightly thicker in some occasions.
2. For any video the play freezes 1-3 secs and at the same time brightness goes low and returns to high when video continue to play.
From my initial research...
