Question about Pioneer DEH-P840MP CD Player

1 Answer

My pioneer deh-p840mp powers on and flips open, and seems to function fine with the exception of no sound going to all my door speakers and the bass to my subwoofers is a far sounding muffle even as I turn up the volume. I un-installed the deck and checked all wires for frying and solid connection and it all seems fine, could this be an internal problem with the deck? Thanks, Marco

Un hook all your speakers that the deck is powering and hook them up one by one sounds like u have a shorted speaker or wire and the unit is going into protection.The best way to chk the speakers and wires is with an ohm meter . Check each speaker wire to ground and across the speaker and see iof you have any shorts. The next step woulk be to remove the unit and have it bench tested.

speaker mounting is key to a good sound, make sure your speakers are mounted well and the wiring is correct, if you get the speaker wiring wrong it will loose all Bass.

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.

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.
