Connected my TV and devices and and set the channel setup in motion. All HDMI devices found recognised and working fine.
After about 2x 4 hours of TV usage HDMI ports stopped working mid-movie, tried to reconnect via "source" select all HDMI ports showing as 'unknown' after numerous attempts.
Did the usual power down unplug even did a hard factory reset and carried out initial setup again. Tried to find devices individually but All HDMI devices that were previously recognised now apppear as 'unknown', one of which is a Samsung BluRay player. TV from my cable provider is fine perfect picture and sound.
