after few seconds these vertical lines appear

I had more like same problem but my lines don't go away. When i turn my tv on its ok but after few seconds these vertical lines appear. Also there is a horizontal line till that line the vertical lines developes .

Any way to fix it?

Is this photo ok?

Sony w800D 43 inch

Vertical lines only at bottom. Which changes according to the image. Like if there is no colour for example if it is black then you can't see the lines.

Funny thing is that when i removed everything then put everything back the tv is not working. Not even standby light is on.

I had discussed this problem like a year ago with you. But that time red light was blinking 5 times. But it fixed after replacing it with new tcon board.

But now after many tries the tv turns on sometimes but backlight was not turning on. And today somehow it turned on with black light. Now it showing red , green , blue in screen like for few seconds each colour comes and goes. But when I looked now it horizontal lines. Not the lines it used to be . I will attach the photos. Most probably the panel will be the problem i think but even though it's panel fault is there any way to fix like try to fix so that I can bring back to normal, even though it's a difficult procedure.

Is this the right one?

I tried to add more clarity photo with detail but it saying it's too large.

I'm also uploading a video just in case NEEDED

After few tries the tv turns on with display but with the lines

I saw a YouTube video of a person fix a tv which have kinda same problem, he used multimeter to check voltage in not the bottom board that I have sent the picture of but side board i thing something like gate drive and then he used a long wire with resistor then he checked by connecting side board and bottom board and when he find the correct one the screen becomes normal. Then he told to connect both side and bottom board (that point) using a jumper wire. The video is not clear and I'm a beginner in this kind of stuff.

I will also provide the link.

The video is in Hindi language ( A language In India) but I don't speak it because we talk different languages but i understand it not completely but most of it.

Update

I don't know what this problem called but I have seen a post were you refer it as ghosting. To make the problem more clear I'm adding a video. It may help to identify the issue.
