Pioneer pd-f1039 wont power up quit working plug into wall hear click press power nothing comes on? no cd's are in unit spotless clean inside dosent smell electrical

I had the same problem (mine had been connected to a second unit). When I left it plugged in for awhile it started clicking, at that piont I disconnected it from its twin and ran used the remote to fully turn it on, it was sort of half on and half off at that point. Since then it has worked OK.

I suspect my problem was due to using a mono rather than stereo cable for the interconnect between the two of them.

I suggest you plug it in and leave it along, if I'm right it will start clicking ater a time and then you can turn it on and playh a CD then it should be OK.

I tried connecting a ipod cord in the back of the recievers ports and the volume can't be controlled by the reciever, is there a aux input option for this reciever or is it to old.

How did you "connect" an Ipod to the receiver? If you plugged in RCAs then you were probably plugging into the pre-amp outputs of the stereo. There is an aux option from pioneer (CDRB10) which plugs into the blue squarish plug on the back. I think its a CDRB20 if you ever wanted to add a CD changer as well.

How do you hook up your ipod through the rca cable hookups in the back without the radio still playing?

This is different on every stereo, but generally the RCA ports in the back of the stereo are labeled "Aux" or something to that extent.

First, you must purchase a headphone jack to RCA cable which can connect to both your stereo and your ipod.

Connect the cable, turn your ipod on and start playing a song. Turn the volume on the stereo to a moderate volume so you can hear when the song is being played through your stereo. Then, using the selector switch, turn the stereo from "Radio" to "Aux" or whatever it says next to the the RCA plug ins on the back.

I can't figure out how to put my pioneer deh 10 in auxiliary mode. I bought one of those audio cables to plug in the red and white jacks in the back, and connect my mp3 player, and I can't figure out how...

Sorry, but I don't think you can use the rca's for an aux-in. I bought a deh-10 new and there is nothing in the owners manual that even mentions useing the rca's for an aux-in.
Used it long enough to opperate it in the dark and nothing in the setup menues for changing those rca's from outs to ins.

Intermittent faults especially one as intermittent as yours can be very difficul to trace but the first things to check are loose connections on the power supply leads at the back of the radio and if they are ok you will need to dismantle your radio and check for dry joints usually around the plug and if needed resolder these dry joints
