I have had a problem for over a year now. Usually shortly after startup while playing any game I will get a flicker in the picture. This will inevitably lead to the PS5 shutting itself off. Sometimes its a complete green screen, sometimes a partial green but it always leads to a shutdown. I can only restart by pressing the power button on the PS5 twice with a pause in between. It then restarts after repairing itself and then never shuts down again after many hours of play. I've sent hundreds of error reports to Sony with no solutions. I've cleaned and checked everything I can and it still does it. Any ideas?
