Nothing yet .I tried a different hdmi cable for a few days and it was good. Then I swapped it out for what I thought was an upgrade and it started doing it again .I will switch back to previous one and update the post later .
I hear you. I switched out the HDMI cables as well .one of them it started doing it that afternoon and the next few days so I swapped it out with another one .so far so good. It's been about 4 or 5 days .So.... I don't want to say I've solved it for sure until I wait a little longer. I will keep posting updates. But try switching out for more canles. FYI the one it seems to be working on is an old monster HDMI I cable I've had for a few years .
