CEC issues with TCL TV and Sony AVR

having intermittent but recurring issues with the TCL TV not switching the Sony inputs correctly on powering up. Requires endless fiddling about.

WAF in unusually deep negative territory.

Roku 7101X s/w v. 9.10 build 4129-30

Sony STR-DH770

Harmony Hub & smart remote

I know it's all low end stuff, but it should work consistently, shouldn't it?

Thanks for looking.

Re: CEC issues with TCL TV and Sony AVR

CEC between different manufacturer's devices is always hit or miss. And sometimes it's even different between different products from the same company. I had all sorts of problems with my Samsung TV and a Yamaha AVR, but when I replaced the AVR with a new Yamaha, it's worked perfectly since. I don't think there's anything "wrong" with any of your devices. It's just the way they decide to work together. Sometimes a firmware update will help, and sometimes it makes it worse. Again with my gear, Samsung had a number of updates that really messed up CEC and ARC, but then they finally got it nailed down.

Re: CEC issues with TCL TV and Sony AVR

Thanks. Unfortunately (and predictably, I suppose) no updates/downloads available for the Sony. The TCL Roku still receives updates. Whether this will ever improve interacting with the Sony is, as gamblers might say, a crapshoot.

Re: CEC issues with TCL TV and Sony AVR

Same problem here with my Denon receiver and TCL Roku TV.  Problems started after 9.1 Roku update.
