Question about Denon AVR-3802 Receiver

1 Answer

Denon avr-3802 Hi; We've had this receiver for about 7 years. This past year we've experienced intermitent lose of sound when playing the dvd. Now we've lost sound out of the CD player. TV/Sat works fine. All connections have been checked multiple times and the Cd player has been verified to work ok with an older reciever (20 years new). We've reset the processor a couple of times. Are there any user changible fuses we should look at? Should we take it in for servicing? Or is it time to get a new receiver? Any suggestions appreciated. Thanks

It sounds like this is one of two problems. 1) It has lost the connection to those inputs entirely. If so the solutions are rather simple. Unplug it and maybe even ground yourself. Open the receiver and check any wires going towards the inputs in question. Also check all the fuses, they should look just like a normal glass vial fuse with the two metal connections. If you can tell that the fuse is dead, find out what type of fuse it is (maybe printed in the user manual or on the fuse itself). Then replace the fuse. 2) If it has to be programed for the particular inputs then there might be a battery dead. simply begin the same way you did with the other solution and this time look for a round battery. It is most likely a 2032 and I would suggest replacing them all. To replace: If it is inset to the board note the polarity, pop it out with a screwdriver or fingers, put the new battery in the same way. If it is raised, note the polarity, remove from the connectors, push the connectors together so that they are slightly closer together than would allow a 2032 to fit passing through(so that it would be snug), and put the new battery in the same way.

Denon 3802 connected to blu ray player but playi g dvds, how do i get dd 5.1?

You cannot get 5.1 sound from DVDs that are not encoded with 5.1 sound. They may be stereo, which will only send sound to the main front L/R speakers.

Hi Expert, My Denon 3802 receiver's digital inputs are not functioning. I can't get any sound from de digital coax nor from the optical input. What can be the case here ?

Not knowing if this is a sudden onset or setup issue I recommend you hit the manual and (re)check the digital source assignments. Also, any Tape Monitor activation will effectively silence digital inputs. Familiarize yourself with the controls and their interactions.

Denon AVR-3802 Problem

Check that your speaker cables are not touching each other at the amp end and also at the speakers as this will cause the amp to shut down.

hope this helps.

Denon AVR 1705-no audio on TV

I have had the same problem and was told that it is a "board" inside. Essentially it has lost the surround sound ability and can only play things in Direct/Stereo. Mine is just over 2 years and I originally thought my kids had hit a button on the thing causing the issue...ended up paying $100 to trouble shoot it and confirm that it is internal and more expensive to fix than replace. Can't say that I will be buying a Denon again.

Set up

You don't need to fake it with a VCR - on the back left side near the bottom there is a Monitor section with an RCA connection and an S-Video connection. Connect one of these to an input connection on your tv and switch your tv to show that input. Select the AMP setting of your remote and press Setup.

Losing treble at higher volume

There are two things. First check the sound settings of the DVD player. It might be putting out a lower quality sound on the CD side of things.
Secondly try to determine if the speaker tweeters are working. Connect the speakers if you can to another sound source. If the speakers are good and the settings fine. Then you have a fault in the amp unit.
