Does it turn on but you hear no sound?

If my memory serves me right, it does not have an internal amplifier. If you do not have speaker wires on the wiring harness that came with the unit new, then you need an external amplifier to hear the music.

It will have RCA jacks on the radio, and that is what you connect to the external amplifier to hear sound. You will also need to connect the blue wire to the remote turn on of the amplifier to turn the amp on.

Let me know if you need and more help and if the radio turns on with no sound or if it is dead.

Personally I would just replace the radio. In dash changers go bad easily and are basically just a problem waiting to happen. The average life span of an in dash changer is about two years.

Cd changer is mainly a mechanical unit, most common problems are caused by gears and dirty lens.
Try disconnecting the cd changer power cable and connecting it back, if it reset the changer it will restart working normally, if not you have to replace or take out for repair the cd changer.

Got used car 1996 and it has a 10 cd changer in it . Was installed at time of purchase of new car. Have noidea how to use it. Don't know if it works, or not. No light goes on, no buzzing, Someone told...

These changers are capable of outputting to several bandwidths (like 93.5, 103.5, etc.). Does it have a wired remote mounted somewhere on the dash? If it does, it's likely the type that uses FM modulation. If that's the case, put disks in the cartridge, insert the cartridge, and hit play on the remote.

If it doesn't have the remote, it runs directly off the stereo in the dash, in which case you change inputs by pushing the Input or CD button on the stereo in the dash, then control it from there.

Let me know which it is, and I'll try to help you further. Also, a brand and model number would help in finding an online owner's manual for you to peruse.

The sound output from my 6 disc changer in my mazda6 isn't working.

Check in the back of the receiver, I had this same problem and it was because the output cable had come unplugged. Take out the CD Changer, and check to make sure all of the wiring in the back is secure. You will want to test the CD changer before you put it back in the dash.
