Hello, I need emergency help please I have a anthem mrx700 that was running perfectly fine up until now on software version 50.12 I tried upgrading tonight to version 50.16, everything was going fine with the upgrade and then at a certain point I got an error message I had no choice and had to stop the upgrade now the unit will not power on no matter what I even tried unplugging it for about 2 min. tried upgrading to the old 50.12 and 50.16 also tried quick measure in the room correction but I keep getting the message connection failed cannot find unit now I am stuck with a unit that will not power on please help any suggestions? I looked in the manual and there does not seem to be any reset options or circuit breaker fuses etc.

Have you called Anthem yet? They should be most helpful. Post your outcome. Their HT receiver is one of the few I would consider. Good luck, hope others here can be of aid.
