Try a different vehicle if it still dont work it is a resistor in the heat sync and the unit over heated common on CDA-9827 thats why it has a fan alpine co tryed to fix the problem and it dont work well obviously the resistor should be very noticable when you open the case work up remove the cd unit 4 screws at each corner in the back right corner is where youll be looking it should be a gient grey or brown looking thing with rings on it ddont touch it wright down the coulors on it in reading order of appearence this determins the ohms (Resistance) of the resistor if it is not there it will be two metal things sticking up that look like this __, ,__
) '' '' ( your local radeoshack should have the part/s youl need the black one under it may have also been damaged by the heat if it did it should only cost pennys on the dollar to repair probbably around $8.00US Currency if you brought it to my place i would charge around $70.00US Currency so yeah its pretty easy to do your self youl need a peice of card board to practice on a 25Watt no more soldering iron if you go more than 25Watts you will dammage the motherboard youl also need fresh rosin core solder a steady hand and a little patience easy does it you dont usualy get a second chance so be carfull tip use a solder pen and give it at least 5 mins to heat or your solder wont bond

Pioneer deh p480mp..not able to get radio to turn on. I have power to harness. Good ground just seems as if no power to face plate...contacts appear to be clean any suggestions?


hi jeff, recheck the power wiring again namely the yellow,red and black wires. when the harness is wired and then connected to the unit you will notice that the cd eject motor will run for a few seconds. this is a good sign that the unit is correcly wired up. make sure that both the re and yellow wires receives +12v once the vehicle is started. if this does not help then the rest of the problem lay inside ur unit. cheers.

The head unit should have two separate +12V connections: One that goes to a switched 12V power that is switched on/off via the ignition and one that is always energized at +12V. If the head unit's switched +12V lead is not connected, the unit will not turn on (except for when +12V is first applied to the "always on" lead, in which case it will immediately eject the CD). Please respond if this is not the issue. Hope this helps!

Why won't my cd player eject?


Hi Darla ,

If your problem is with new cd's your trying to play then the try this. New cd's often have around the inner and outter edges and if such disc is used, this may be the reason why it wont play. What you do is take a pencil and use the side of the pencil to rub the edges of the cd. It should clear it up. Now if your problem if that it wont let the cd come out the only thing i can think of is to press and hold the EJECT button and CD button at the same time for more than two seconds. Good Luck =)

I had the same problem, CD not accepted by unit and pressing source button to select CD player causes unit to display reset.
Using reset button just causes unit to 'whir' for a while, problem is not solved. Firstly with unit switched off, and the ignition off I inserted a CD using some gentle force, I then inserted a second CD, forcing it in over the top of the first. Next I pressed and held the reset button for a short time before releasing it. Both CDs were ejected, when the unit had stopped I took the CDs out, replaced the front panel and turned on the ignition, The unit will now accept CDs and eject them O.K.

(This did take two attempts to get right). Seems to reset the eject status of the CD player.

Won't turn on


My only other hypothesis is that, similar to my wife's Kenwood deck that has the MASK motorized faceplate, the flex cable that connects the moving faceplate portion to the main unit has started to crack and lose connection. After a few years of moving back and forth, folding and unfolding, this seems to be a pretty common thing. I was able to replace the flex cable on my wife's deck, but only because I stumbled across detailed instructions (with pictures!) and I got lucky with the replacement cable being in stock at a local repair shop. Your mileage may vary :)
