White lines on Samsung q90 82"

[pedz55]

Hi, my Samsung Q90 82" OLED started showing white static lines randomly, some times they show up and sometimes they don't.  Any suggestions on the cause and if there is a way to fix?

It doesn't appear to be specific to an input (I just the Samsung harmon/kardon soundbar for hdmi inputs).  If I put on my Apple TV it happens, and if I turn it off and just use the Samsung native interface it happens.

Also can't get the settings menu up, the remote buttons aren't working as expected (though I know the remote itself works because power on/off works every time).

Thanks for any help you can give,

Peter

I would check your cables and for loose connections. You could try to unplug the tv from the outlet for a few minutes, then plug the tv back in to see if that may help.

Thanks, I did check cables, haven't tried unplugging, will do when it happens again.

Factory reset the TV. It could be corrupt firmware.
