I obtained this unit recently and could not get the on screen set-up to come on. I did take it in to a registered Denon repair shop and had a diagnostic run. I found from the tech that the main system control micro has gone bad. According to what he told me there must have been some sort of electrical spike that took it out. He gave me a quote of apporox $300 to fix. If I could get the schematic and the part I feel I could take care of it myself. Need to know where to go for this information. I would greatly appreciate any and all feed back on this!

Re: main system control micro
I can try to get you the part number, but the micro willbe a surface-mounted multi-pin IC. These are not the easiest to replace without the proper training and equipment. Normally, the entire board is swapped out. I suspect that the majority of the cost is for the board. Realize too that the cost of the board to you will be higher than the cost to the servicer.

I had a similar issue with another denon model solved it by buying a cheap replacement remote for denon multiple models, make sure it covers your model. It looks better than the old one and covers every function.
Check sound from headphones. These models have been known to have bad headphone jacks that make the unit think there are headphones plugged in even when there isn't. Sometimes just plugging in headphones and unplugging them will fix it for a while.
zone 2 volume can be adjusted by zone2 remote control (small one which came with the unit) or by main remote control if you switch it to zone2 mode. My main rem control has a slide switch i have to put in zone 2 position to operate zone 2 amp.
Try doing a factory reset by turning off main power switch.hold down speaker a and b buttons while turning on main power switch ,display will flash 3 time s then release buttons,this then returns unit to factory default settings.
I cannot access the setup menu on the unit display or via the s-video monitor out -- everything was working fine a few days ago. I have reset micro, unplugged all night, reset again, and still cannot get to the menu in order to correct connections, esp for digital. My problem is on the avr5600 but seems like this happens on many of the denon units
1 Your DSP board is toast. ( not much hope, it must be sent to Denon as they do not have anymore entire circuit boards for swap-out replacement.
2. Heres the hope part......Inside your denon is like a computer.....there is a main board, separated by the big silver heatsink, and then there another main board. On the main board closest to the volume control, the DSP boards and Video boards plug into the main board . The DSP and video boards are up and down ( when the receiver is laying flat, like normally ), and they plug into the main board from the top.
Denon is NOTORIOUS for bad solder joints and the little white connectors that connect the "motherboard" to the DSP and Video boards are of suspect quality ( the rest of the unit is great )....So it COULD be that you have a bad solder joint on one of the connectors or the connector itself. There is also another set of connectors that joins the front panel display to this "motherboard".....these colder connections are also suspect.
I would have a denon repair shop look at it as I GUARANTEE they have seen this before.......best of luck...Rob
The Denon AVR-2801 receiver outputs the "on-screen" menu and interface with priority to the S-VIDEO output of the unit.
If you have any S-VIDEO cables plugged in, you will need to navigate to the appropriate S-VIDEO input on your television/monitor to be able to see the on-screen menus.
If you need additional help, please feel free to leave a message here and here is a link to the manual that explains the menu and on-screen functions in more depth. Especially see the "notes" section on page 14. I have had several of these Denon amps and the only input I could get the "on-screen" menu was the S-VIDEO MONITOR input.
