As a born tech, I have to help try and solve this problem. I'll go away if you want me to, but I'll feel bad about it. So first a question: is the power light orange around the lower power button? Is the upper power button engaged? Here's the reset procedure from the manual (sorry about the formatting...):
Processor Reset
In the rare case where the unit�s operation or the dis-
plays seem abnormal,the cause may involve the erratic
operation of the system�s memory or microprocessor.
Tocorrect this problem,first unplug the unit from the
AC wall outlet and wait at least three minutes. After the
pause,reconnect the AC power cord and check the
unit�s operation.If the system still malfunctions,a sys-
tem reset may clear the problem.
To clear the AVR 7200�s entire system memory
including tuner presets,output level settings,delay
times and speaker configuration data,first put the unit
in Standby by pressing the System Power Control
Button. Next, press and hold the Surround
Mode Group Selector and the TunerMode
Selector buttons for three seconds.
The unit will turn on automatically and display the
RESETmessage in the Main Information
Display ̃.
NOTE: Resetting the processor will erase any configu-
ration settings you have made for speakers,output
levels,surround modes,digital input assignments as
well as the tuner presets.After a reset the unit will be
returned to the factory presets,and all settings for
these items must be reentered.
If the system is still operating incorrectly,there may
have been an electronic discharge or severe AC line
interference that has corrupted the memory or
microprocessor.
