Flashing TV image unless AV amp removed

My Anthem MRX520, Pioneer Kuro TV and Virgin 360 box was working perfectly. I then changed the Kuro for a Panasonic TX-65jz1500B (2021) and connected to its HDMI 1. The result is the TV showing a program image for just two seconds then no image just continually changing text showing different resolution modes. The AV amp screen showed 4K. The TV Home button correctly showed the Home page with App options.

I disconnected the AV amp and connected the same HDMI cable directly to the Virgin 360 box and the problem was gone. What might be the cause of this failure and what can I try to fix it?

Check hdmi mode option in the Panny TV input (when connected back up). Mode1/2 may make all the difference?

However note that HDMI 2 on Panny TVs is used for ARC... and is the one the AVR should be connected to to allow ARC to function.
