Check cables, see if other audio sources work through audio input ports.

The speakers on TV mode work but when I go to play DVD no sound.


How have you connected sound from the DVD player to your AVR-5805? If optical (a good choice because it sends surround sound with one cable) then you will need to choose optical audio in your DVD signal path. Similarly, you need to choose analogue if used or even composite (not a good choice)

Why does my avr 100 say OPTI.when i try to play the radio, and no sound comes out


It is trying to input a signal via the Optical digital input. You need to switch the input control on the front panel or remote to Analog.

It seems you are not unfamiliar with censorable abbreviations.

RTFM and go through all the settings again.

Your unspecified external devices all have settings, cables and (if digital) the ports on the Denon may need to be assigned.

You don't say how "TV audio" is entering the system.

My guess is you're using analog audio Out from the TV into an analog input on the Denon. One channel failing would probably be the Left Channel cable failing or not seated.

I always recommend bypassing the TV audio entirely if the programming comes from somewhere other than its own antenna, as TV audio electronics add nothing good to the process.

If you're using cable box, sat box, game, whatever, ITS audio is best sent directly to your Denon's specialized audio hardware - digitally, if possible, to preserve multichannel possibilities.

You could also run standard analog audio from the cable box to the TV analog Audio IN if you just want to watch news and weather on TV speakers without the Denon involved.

Volume control works in DVD mode but not in TV


Where is your TV sound coming from? Is there a volume control at the source?

No sound from left fronts (A+B) in TV mode.


Just check the rca cables. Try wiggling the cables as well. If they are the plastic rca cables, they do to wear out quick.
If it is not the cables, than it is a shorted resistor in the channel sound output

Denon AVR1602


I know the avr 1602 well....What exactly do you mean "I have my TV cable service wired to the Denon".....Do you mean the actual co-ax cable ?....

The denon is only able to switch raw video and audio signals.

What do I mean by that ?....IF you are running your co-ax cable from your cable company directly into the back of the denon, it won't work. The Denon has an AM-FM tuner, but not a video tuner ( channels 1-121)....If this is what you are doing, then you want to run it to your samsung first ( as long as the samsung has a tuner so you can change channels ).

If the samsung operates like an old VCR, whereby you can plug the cable company co-ax cable into the back of it, and change channels with the samsung, then that is what you must do. You would then hook up the OUTPUTS of the samsing to the VCR or DVD inputs on the Denon receiver. ( use DVD inputs on the denon if the samsung has optical audio out, and use an optical cable as well for better sound ).

You would then use the Denon for the sound, and hook up your TV to the Monitor out jack on the back of the Denon.

The Denon is like a big switchbox. You plug your DVD, VCR, Satellite, video game, or what-have-you into the Denon. Then you use the denon to route the signal to your TV for the picture, and the denon takes care of the sound.

Hope this helps, and remember to always follow your owners manual.......Rob
