Facing TV Problems? Ask a TV Technician.
Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Am I understanding correctly that you're getting horizontal lines? Are they all the way across the screen? Do they ever move or change?
You can upload the video here or send a link to it.
Thanks for confirming.
There are a few possible causes of that, we'd suspect the main board first, then the tcon, and lastly the panel.
Since you've already replaced the main, the tcon is the most likely issue here. The panel is possible, but since the lines are intermittent I don't expect that is the case, which is good news for you as that is something that cannot be fixed.

Yes, it does give that disclaimer, which I mentioned as a possibility also. Their info is not very detailed though, because your lines are not solid and fixed (they change shape, move, etc) that is not likely to be the panel (but still possible). Replacing the tcon would be the prudent step at this point. If that still didn't work, then it would indicate the panel however.
Did you still need help with this?
