I have 4 65" QN95Bs used as horizontal monitors, with the oneconnect vertical behind them. They have a strange tendency to go black screen when Im not around, like a screen saver. But they can't be awakened. Unplug and plug them back in probably does it, but since they are mounted with that plug hard to get to, I fix them by flipping the breaker off and on again. One of them has gone dark and I can't fix it. New main board and new qled control board had no effect. The remote turns the tv on and off as seen in the red light, and I can hear sound effects when I push the selector to the sides or hit the netflix button on the remote. Just can't get anything on the screen.

Sounds like a service-related matter with it continuing after having those parts replaced, usually that's an indicator of a main board malfunction, maybe something wasn't put back correctly or something?
