Re: Samsung QN70Q6DTA Ghost or horizontal lines after tape fix horizontal line

His may be panel but I believe mine is mainboard. Mine turns on properly and displays a clear image for 5 or so minutes and then reboots to a stuttery, slow, bootloop.

I will test out blocking those pins tonight. The thing is sometimes my tv boots up normal and only after using the remote does it reboot to an image with lines. I guess it could be a short somewhere but seems odd it would be able to produce a clear image at all if something was shorted on the panel boards. Unplugging each half of the panel at a time and it boots up normally but with no image just backlights. Gonna test the board tonight and see if anything is off. Again though I think we have the same...

Same tv, same issue. Sometimes the picture is fine though. Usually it will boot up to a clear screen then after flipping through the menu for a few seconds it will reboot to a screen like you posted in pic 1. I'm wondering if may just be the mainboard for yours as well as I can't seem to isolate the issue to either side of the panel and it sometimes works with no screen issues.

Hi, I've always had an interest in repairing electronics. Only recently decided to try my hand on tvs a great deal came up on a pricey set. Looking to learn and help if possible.
