I have the DEH-1200MP model super tuner 3 and it would not power up after battery died and was jumped. There is a fuse at the back of the stereo that I unplugged and plugged back in and then the stereo powered up. I had already checked all of the other fuses. Took me a while to figure this out.

The media your are attempting to play is not in the correct format.
Does it do it with all discs, or only a particular one?

Thanks!

much easier way is to go to best buy or ebay and just buy the plug for 5 bucks. not worth the time and money when you can buy it for cheaper. here is one

good luck and i hoe i saved you alot of time and aggravation!

the yellow is your acc and the red is hot the black is ground and the blue is remote and the rest of the wires should be speakers

you have a stereo rca plug set to a mono audio plug.
you need a stereo rca plug set to a stereo audio plug

You can either hook up the left channel only or buy a splitter that separates one input into two outputs.

If the negative ground was not disconnected, you may have popped a fuse on the radio, if it has one. Check the back of the radio and the fuses there. Always remember to disconnect the ground when working with the electrical system.

Disconnect the battery for an hour. This will reset the stereo and usually the problem will go away when you reconnect the battery.

The mini jack was not designed to work in the manner in which you are trying to use it. The stereo output is always going to be at a higher output rate than the amplifier output. if you want to use an MP3 player with your stereo you will have to purchase a head unit with a built-in MP3 input or deal with the lower rate of volume.

The aux on the back are usually outputs for amps and subs. If there IS and aux in, it is usually on the front panel and accepts a mini stereo plug.

is the light on the amplifier on. is your remote wire the blue wire with power. if not you have a remote problem but if it all works check your rca's on the radio or your amplifier.

you need to make sure the yellow wire has constant +12v it should be unswitched source
