CD player works fine and have sound, Tuner plays but no sound

Tuner section on receiver is fubar. No fuses specific to tuner.

Does you car volume get lower when you stop. If not sounds like an internal issue. No sound at all my brother hooked his up and when he switched to tuner everything would go through the subs but you would not know it sounded like his 6x9s no bass. was a wiring issue. I dont know if this helped or not.

did you hook the constant power wire up? its the yellow wire coming out of the deck. if this was not hooked up the deck would work fine, but it would not hold the time, or preset stations either

I have the same problem with the same model, the radio stations cannot be heard, I am in Mexico, they tell me that it is the radio tuner that does not work

The system does have a remote (at least it should come with one if purchased new), and you need it to control pretty much everything. Here's what the manual says about the radio tuner (you can find the whole manual here) :

Manual Tuning
1. Connect the FM aerial and the AM loop antenna at the back of the unit. Rotate the AM loop for
better reception.
2. Press TUNER to enter TUNER mode and toggle between FM and AM.
3. When the FM station broadcasts Stereo sound, ST is displayed.
4. Tune a station by pressing repeatedly the TUNER+/- buttons until the desired station is found.
Alternatively, you can press and hold the same buttons down for about one second to activate
the automatic search function. In this mode the player will automatically tune frequencies until
it finds a station.
5. Repeat step 4 to tune to another radio station.

Storing radio stations
The player can store up to 30 radio stations in its memory. You can enter every single radio station
yourself or the player can store all available radio stations automatically in ascending order.
Automatic preset programming
1. Press TUNER to enter the Tuner mode.
2. Press and hold TUNER down for 3 seconds to start automatic preset programming.
Note: A weak signal can affect the "Automatic preset programming" function's efficiency. Adjust the aerial for better
reception and a more efficient search.
3. Radio frequencies will be browsed and radio stations stored automaitcally. When all the available
radio stations are stored or all 30 memory locations are full, the auto preset programming
function will stop.

Manual preset
1. Tune to a radio station (see "Manual tuning" for details).
2. Press MEMORY once to enter flashing Preset Loaction number.
3. While the Preset Location number is still flashing, input your desired preset number (1-30) using
the numeric buttons or press the CH+/- buttons, then press MEMORY to store it.

Retrieving preset stations
1. Press TUNER to enter the Tuner mode.
2. Press CH+/- to search up or down for the preset stations or directly press the numeric buttons.

As you see, you really need that remote. The same is true for disc play. While there are front panel buttons for play/stop, disc skip, and drawer open/close, you don't have any other control without the remote. Without the remote control you'll find this system won't do too much, unfortunately. If you bought this new, check the packing material before you throw it away to make sure the remote's not still somewhere in the box. They often come tucked into slots on the foam inserts.

Also, when you hook the unit to a TV, it's just using the TV as a video display device. The TV has nothing to do with any of the system's other functions.

I hope you have luck locating the remote! Thanks for using Fixya.

The tuner is the best source for testing audio issues from a receiver since it uses an internal source for audio. This problem could be two separate issues. Check the tuning in the tuner to make sure it is on a station that you are receiving. The newer Denons will not play any audio is the station is not coming in. Be sure your antenna is connected and tune the station to one that comes in clear.
What source is hooked up to the V. Aux? If an iPod it is common that the volume on the ipod is down .

sounds like u have a premium sound system. what u need to do is take ur blue/white remotewire to ur blue power antennat that should activate ur factory amp.

Make sure your receiver is hooked up to proper AM and FM antennae. Try switching to AM, scan stations. If you hear AM static and/or weak signals the problem could be antennas are not hooked up. FM has AFT which blocks out weak or noisey stations and you wont hear anything without ant.

Does this CD play in any other unit?
Does your player other CDs fine?

on the front panel, look for a tiny pinhole and insert a pin while powered up to reset
