Question about Pioneer Premier DEH-P480MP CD Player

1 Answer

Some buttons don't work anymore...

The buttons "Audio", "Fonction", "Down" and "Right" don't work anymore.. I checked the switches with a multimeter and they are OK. I cleaned the contacts between the front panel and the amplifier but the problem was not resolved. Everything is working if I use the remote control, so this is a hardware problem but.. where??? thanks!!!

If this unit has a "flip face" then I would suspect the ribbon cable that goes from the face to the main circuit board.

Hi, I have a pioneer DEH-P5500MP which always worked just fine but now when there is no cd in the radio it won't play so i try the source button but that doesn't work so i put a cd in and it starts...

It sounds like you may have a bad switch. If you have a multimeter you can check the switches for resistance. If the reading on any of the switches is less than a few megaohms it is probably bad.

Bought a car with the pioneer deh-p4300 in it and don't know how to set the clock,did not receive the paper work

I've had two Pioneer CD players and they both were set the same way. Turn it off then press and hold the AUDIO button if it has one. Then keep pressing it until it gets to the clock. I think on mine the hour starts flashing. When your done just turn it back on. == Answer == I had this problem too. In the far right corner is the "A" (Audio) button. Turn the stereo off and hold the "A" button until the clock comes on. The hour will be blinking. Use the up and down "Select" keys to set that. Then use the right "Select" key to switch to the minutes. Use the up and down keys to set the minutes. Push the "A" button when you're done.

Assuming you're talking about your amp is overheating, it usually means that you don't have enough room for your ventilation. You can keep it where it is, and wire a couple of computer fans from Radio Shack.You should wire them up so that they turn on with a switch. Another problem is the amp is basically out in the open, speakers could be wired incorrectly. If your amp is stable down to 4 Ohms, and you have them wired down to 2 Ohms your amp can run hot. The way to check this is to hook up a multimeter and see what Ohm load your amp is "seeing." If you don't have access to one, then just simply go to a local audio store and ask them to check that for you.

My sony cdx s1000, the source button does not work,therefore i cannot get the radio to tune into any stations.the cd player works but the various buttons have no effect on volume,skip tracks,shuffle etc.

you may have a bad switch. if you can you can use a multimeter to check the resistance of the switches. anything less than a few megaohms, denotes a bad switch usually.

The panel will no longer recognize some of the buttons. for example, the source button doesn't work nor the push-menu. the power and eject button still works. How do i fix this?

it is possible ;you may have a bad switch. if you have a multimeter, try checking all the switches. if one or more is less than a few megaohms, it may be bad.
