I had an issue with powering on the tv in which pressing the lg power button on the first ocassion did not turn on my Oled C1 77 inch Tv.
LG replaced the powerboard, however since the replacement I have an issue with intermittent audio dropouts via earc.
EARC has functioned previously on my Tv when connected to an Anthem 710 receiver and for a few months now on an Anthem AVM 70.
The set up has remained the same in terms of audio settings, passthough, match screen and sound set to bypass and I have tried multiple cables, switching the tv off, resetting earc, but I still have the issue.
It is very odd that after a replacement power board I have this issue. It almost seems like a comparability issue between the new board and the existing components or something else is wrong with the TV.
Any ideas?

Question

I have an LG C1 55 connected to a Denon x2100w AVR on HDMI 2 (arc)... It always worked perfectly... After the latest TV upgrade I can't get anymore TV audio on the AVR.
I tried disconnecting and reconnecting everything, unplugging stuff for minutes, switching multiple hdmi sources... The AVR can send data to the TV, but it doesn't see TV audio signal.
All the HDMI audio settings on the TV are greyed out and disabled.
Next thing I'll try to reset to factory defaults, but I suspect it won't fix anything...
Note this worked flawlessly for 2 years.
Ideas are welcome.
