If you’re trying to fully rely on CEC commands from the remote itself, that’s where compatibility gets tricky with older sets.

If you want, tell me what devices you’re trying to control (AVR, streaming box, etc.), I can suggest a cleaner setup 👍

i came across this page while researching remote controls for my panasonic th-65pz850u plasma tv, and i have to say, the ce control wiki is exactly the kind of resource i've been looking for. finding detailed information about cec compatibility and programmable remote options for specific tv models can be really challenging, so i appreciate that this wiki exists.

i own the th-65pz850u and have been trying to set up a universal remote to control all my devices through hdmi-cec. the panasonic plasmas from this era had pretty solid cec implementation, but it's not always easy to find which remotes work best with them. if anyone has recommendations for remotes that work well with this tv's control features, i'd love to hear them!
