Question about Denon AVR-3802 Receiver

6 Answers

Main system control micro

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!

    I appreciate the initial feed back on my issue, however I do have a great deal of electronics repair experience. IF I need to replace the entire board I am willing to do so. However I do need to find a supplier for this part or try to find a "junked" unit that still has a good board.

    After a good deal of research on this unit, I did find that it is worth the repair and that I could actually get the work taken care of for less than I could buy the part for. definitely worth the $$ to take it to a qualified repair shop. I do appreciate the feed back given. Looking forward to a receiver after the first of the year.

Here you find ll replacement parts for Denon AVR 3802.



You probably need to replace the control pwb that costs $137: 1U-3338G

The service manual costs $25.

$ 300 for the repair was a good quote.

Its always better to go for authorized supplier,  but since its expensive, I would suggest you to go for a used product from junk store or ebay.

Hi,

A few ideas that might be of additional information:

  • to my knowledge the Denon AVR-1082 is identical to the AVR-3802;
  • try "for salvage"/as-is units from Craigslist or eBay;
  • try back the registered Denon repair shop or any other audio/electronics shops and check if they have "unclaimed units" for liquidation.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.

Here is the part number for the main micro processor, ref # IC303 on the control board

2622970008

The board is very unlikely to be available. But here is that part number for the control board

1U-3338G-1

Here is a place that sells Denon parts, they will know if the board is available.

Please rate this by accepting it, or not accepting it. This information came right out of the Denon service manual for your model number.

You need to contact denon directly in order to get the parts .

You can also get service manual from the for connecting it .

It is not good to get the control part from any other site other than denon .

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 reinitialized my 2307ci receiver and cannot get on on screen menu


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.

How do i connect my denon RC7000CI to denon amp. 2801


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

Audio Problems with AVR-2803


Hmmmmm Sounds like one of 2 things....

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 System Set up Menu does not display to my monitor.


Hi there,

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.

Good luck!
