Question about Pioneer DEH-P840MP CD Player

1 Answer

Lights blinking Hi I have the pioneer deh p840mp / p850mp model. Ive replaced the ribbon cable twice because they went bad but now the unit blinks on both display panels and wont make any noise other than a flicking sound as it powers up and down every 2 seconds. But when my car sits in the sun this doesn't happen. I don't get it. Something must get warm and connect right but I've inspected and can't find anything.

Pioneer DEH-P850MP Features quit working when opened


those radios have a ribbon wire that breaks on them this is why it doesn't respond to your commands. pioneerelectronics.com and parts.com and or ebay.com sells the ribbon wires. the wire is located inback of the part where the faceplate hooks up to.you can see silver ovals on a black rectangle where the faceplate makes contact. that is the part.

Not working at all


Its the ribbon cable which connects the faceplate to the main unit.
The bad thing about these types of receivers, is after a lot of flip downs and flip up, the wires in the ribbon cable get weak and break.

If you want to fix it yourself:

I had this same problem, and was able to fix it myself.

Best of luck!!

Pioneer deh-p840mp weird concern


this is a problem that is caused by the ribbon cable that connects the two faces going bad - you can find repair kits for this unit on ebay.. just search DEH-P840MP and you will find "ribbon kits" or repair kits. They are usually about 15 dollars.

Pioneer deh-p850mp problem


Check the ribbon cable on the inside that connects the two parts.

You will need to remove the faceplate and open up the Rear of the unit.
If you bought it used, theres a good chance that the ribbon is in fact broken. If its new, check the connections on the ribbon cable.

It is a chronic problem with most all PIONEER units that fold down / out.



Best of Luck.

Unit powers down when faceplate attempts to go to open position


Same thing happened to me twice.

Its the crappy ribbon cable that connects the faceplate to the head unit.

Its only about $12 (USD) from Pioneer directly.

It comes with instructions, its not that difficult.




Best of Luck.
