hi in a previous post I mentioned im having sound loss and locking up issues
on my t2200 I always have the low power setting turned on.
every time I turn the unit on for the first time no matter what time of day while watching normal tv approx 2 hours later the sound suddenly stops and unit locks up wont respond to remote or buttons on the front of the unit I can still see normal tv picture its just like ive turned volume down so to get going again I power off at wall for a min or more then turn back on and its fine till I turn it off again. this happens everytime I turn it on for the first time so once a day has to be powered off at wall to get going.
HOWEVER hopefully this helps you dish tv I have turned the low power setting to off and over the last two plus days the unit is working perfect no issues at all.
so clearly it has something to do with the low power mode.
please look into it
