I've had my AV8801 for two years and have enjoyed it very much until last night. I was watching Alien on Blu-Ray when all of the sudden during switching between menu and movie (I could hear the Blu-Ray players relays switching), the screen went black and the audio silent and it never came back. I switched around to other inputs and was able to hear audio on the cable box for a few seconds when switching around (no picture), but it would die after about 3 seconds.
I tried cycling the power, unplugging the unit for 10 minutes, switching cables, inputs, outputs, zones, doing the power/game/sleep reset (which killed all audio, even the 3 seconds of cable box audio), and finally left it unplugged overnight. Nothing has worked. The unit behaves like it SHOULD work (turns on, I'm able to switch inputs, cycle zones, access menus, and I can hear the test tone when doing the speaker setup thing), but I can't see menus on the TV, nor can I hear any sound from a source. Right now I have everything hooked up directly to the TV and everything is working okay now that the AV8801 is out of the equation.
I bought this off of eBay, advertised as new A-stock from an Authorized dealer (box and unit serial #s
appear to be legit), but after reading Marantz's website, I have my doubts as to whether or not they will honor the warranty. Can't find the dealer listed on their site (I did buy it 2 years ago though).
So, any ideas of anything to try before I take it in for repair?
