listening to the 1070 today and all was working fine but then tried a DVD and the 1070 locked up...sound showed way low with no way to turn up or down the volume

remote wasn't working so I thought...change the batteries...2 new sets and nothing improved...
next I tried the 1070's front controls...sometimes they would change but still the unit was not working right...
next I removed the power from the unit by unplugging the cord at the rear to the 1070 and replugging after a bit of time...no change
lastly I tried the Master Power switch...this seems to have "rebooted" the unit and it is working correctly...for now...

my 1070 went back home in 2016 for a different issue...so hopefully this is not a portent of things to come...
