OK, can you please check the flat ribbon cable plugged securely at main board and into t-con board located at bottom center of TV under metal shield?

I have reexamine the flat ribbon wire from the main board to the T-con board, it is in place, secured, not damaged. i prefer to chat because i have a speech impairment.

Phone call offer is automated sent by website system and not from my side so you may please ignore it if do not want it.

Can you please remove metal shield of t-con board and examine the flat cables from t-con board to inside LCD panel, reinsert the cables to make fresh connection and check if lines remove?

Please handle those flat cables very carefully.

Ok, it's is going to take a few minutes.

No problem, take your time.

Customer: replied 1 year ago.
I did what you suggested, same results, i get vertical and horizontal lines.
Expert:  Shahid replied 1 year ago.

Horizontal lines as well? This is new info and indicates serious problem. It seems LCD panel internal issue, sorry about this news. Entire screen will need to be replaced but would cost more than new TV price of same size if replacement panel/ screen is still available with Samsung parts in area.

I do have service manual of this model but I'm afraid it wont help you to resolve the issue. I trust my input will help you out. Please feel free to respond if you have any additional questions. You would be better off with a new TV instead of spending money and time on this TV.
