Samsung 75"QN75Qn90AAFXZA Horizontal line

[yankys]

Hi, everyone this 75" has horizontal lines and jittering I did a visual check on the ribbon cables and reset them still same results it will work for awhile then reboot and play again, could it be a main board given that the t-con and main board are one.

prolly like this, are your symptoms similar? if so maybe see if you can do the same tests, the models are not the same, so there may be some differences: https://www.youtube.com/watch?v=XCJAx92JwPs

I did that in the video, and no change, both sides remain the same no matter which cable you unhook.

ok, thats a good test, it may just be the mainboard thats the issue then.

Hi, everyone just wanted add that I timed the reboot and it’s 3 minutes each time could this be a mainboard issue tv plays like normal even after the reboot.
