Question about Denon AVR-1800
AVR-1800 Stopped outputing sound. I tried resetting the processor by holding A and B system buttons and turning on main power. Display did not flash as described in manual, so tried several times. Then I turn it on and it worked. Turned it off and back on and can't get it to work again, even with resets. Thinking it's got to be a firmware problem. Any help much appreciated!

SOURCE: No Power
I mwas gonna suggest that you need the speakers attached but you stated later that it did the same thing with the speakers attached. The unit switching off after it checks its self is NOT a normal thing. TAKE IT BACK BEFORE ITS TOO LATE!! GOOD lUCK

connect your right speaker cable to the left output, if the sound comes out then the problem is on the left speaker ( the cable or the speaker itself ), but if still no sound, then the problem is on the power output of the unit, need to repair them

In the rare case where the unit's operation or the displays seem abnormal, the cause may involve the erratic
operation of the system's memory or microprocessor.
To correct 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 system
reset may clear the problem.
To clear the AVR 335's entire system memory including tuner presets, output level settings, delay times and
speaker configuration data, press and hold the Tone Mode Button (5) buttons for three seconds. The unit
will turn on automatically.
NOTE: Resetting the processor will erase any configuration settings you have made for speakers, output
levels, surround modes and digital input assignments, as well as the tuner presets. 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.
If these steps do not solve the problem, consult an authorized Harman Kardon service center.
