Purchased a Sony Bravia TV December 2020, I connected a Panasonic PVR to HDMI2 and it’s worked fine, until now !

I turned the PVR on and selected HDMI2 and got the “No signal” message.

I have tried the troubleshooting info on the web, ie disconnect all HDMI inputs, disconnect the TV power, wait 10 minutes then reconnect 1 by 1 checking for signal for each device, everything works except HDMI2

I tried a brand new DVD player in HDMI2 but still got the “No Signal” message.

Assistance helpful.
