Samsung UN46D7000 vertical lines after 3 hours of turn it On

[argemor]

Hi

I bought this TV 2 years ago and over the last month after the Tv stays turn on for about 3 hours aprox, it appears vertical lines from the right and fills the screen after all day of the TV functioning. The only way that the lines disappears is if a turned off the TV and unpluged from the electrical outlet for about 1 or 2 days (sometimes 3 days), then the problem come up again. I talked with the samsung service (they had not checked the TV) and they told me that it is possible that the panel is damaged, but other friends told me that it seems heats problem. I started to put a fan behind the TV after I turned it off because the lines and it seems that it helps a little, the time I have to wait to turn on the TV and the lines dissapears is 1 day and a half in some cases.

Please I really appreciate your help and some guidelines to address this issue.
Attached are the images after 3 days of functioning the Tv without unpluged.
Thank you

Bad panel by the looks of it.

Tab bonds loosing connection once they heat up.

Thank you for your reply.

In this case, Could the "gap thermal" procedure fix the tab bond heat problem?

Yes if you can pad the bonds down with a thermal pad then it should be good.

I have the same TV & same problem. Got my TV in 2012. Lines started 2 months ago although not quite as bad as yours. Lines are constant. Its a poor reflection on Samsung in that they have numerous QC issues with pricey tvs. I'm not happy.

Hello, I made the tab bond procedure, but when I turned on the TV those lines appear on the screen. At the first moment there was 8 lines, when it pass about one hours 3 lines gone away.

Any further help I really appreciate.

Unfortunately, with these type of tab bond fixes there is no definite way to make them work. If there was, then 1000's of TV's would be saved from the landfill. You've pretty much done all you can.
