I have roughly 300 STBS being controlled by the Shef protocol-


first time I have ever seen a STB shut down analog audio outputs when a TV turned off.


Was there an update since it was first installed and working?

Its been installed and working for three years, I assume there has  been an update in that time.

Did you try turning off CEC in the TV, or was it not worth the experiment and possible added roll of the truck?

I just disconnected the TV since the STB is only used for music and the only reason it was connected to the TV was to verifiy that it came back on the network after a network drop.
