please attach some pictures of what your screen shows. Use this guide Bilder zu einer vorhandenen Frage hinzufügen for that.

Horizontal lines are almost exclusively a panle fault. Once we see what your panel shows we can hopefully get you a better answer.

I would suspect poor connections to the panel. Open up the TV and re-seat all of the cables. Start there and update this with the results.

Hi Dan

Just to clarify , you mean the connection inside the tv and not the aerial cable

That is correct. Since the signal level between the logic board and the panel is so small, it does not take much corrosion or dirt to cause a problem. Simply removing the cable and reinserting it often will "cure" the problem.

that could be a main board issue as well as a panel issue. I would start with the main board, checking the t-con board as well. disconnect all teh wiring form the T-con board to the panel. then just connect one side. Let us know what it shows.
