Have an install about two years old, no prior issues.
Client lost picture to Sony TV from Sony 5000ES AVR. Audio still working(Directv receiver)
Tried power reboot, nothing. I went to site and pressed HDMI out button in the AVR. Went from showing A to off then back to A. Picture came back in. Tested things and seemed ok, for the moment...........
Any idea what the actual issue may be? Maybe try a firmware update at some point? Any thoughts would be appreciated.
