We have seen a significant increase in Decas or STBs dropping off line in the last few weeks.

Yesterday I was at job that had a STB we use only for sonic tap channels that was not responding to IP commands, I connected it to the service monitor installed in the rack to verify IP and restart the network services-

Box starts responding again and the TP in the room is working fine so i figured we are good to go.

I shut off the rack monitor and close up the closet and leave, get a call later that night that the room is not working again.

Today I test the room, no audio

open the rack, turn on the monitor, and verify all the connections are good and then go and retest the room-

All good.


shut down the rack again and then retest just before i go to leave-

no audio-

It appears that the STB is now following a CEC signal from the TV and not sending any analog audio while its connected to a TV in standby.


In this case it was an easy fix, just disconnect the HDMI to the service monitor before i shut of the monitor since we are not using video for that STB.

Anybody else seeing odd behaviors from DirecTV STBs in last few weeks?
