Hey Everyone!!!
I'm a newbie to the forum and am having a problem
with a jammed disc changer on my Pioneer PDR-W839
cd recorder/player. The 3-disc changer is empty and I'm not able to open it using any of the 3 tray just clatters away and tries to open with no success..then finally gives me an E2
error code on the display. Anyone out there in
audiophile-land have any experience with this particular problem and know of a self-fix..or am
I doomed to taking it to a local repair shop here
in Honolulu Hawaii or sending it to a service
center? Any advice to guide me would be greatly
appreciated. Thanks for lending an ear and taking
the time to reply!

I am having the same problem with my PDR-W839. Have you come up with a solution or fix for this problem?

Hey CR:
Bummer huh? No solution yet..though someone did
suggest I look for a pinhole and insert a pin
while unit is powered-on to reset it..but I have
yet to find any pinhole anywhere on the exterior.
I'll post any additional info on this suggestion
when I receive it. In the meantime..good luck
with your 839.

Hey CR:
Received more detailed info on possible fix to
our PDR-W839 changer problem which goes like this
"look for a pinhole in the area of the CD tray to
insert a pin..similar to the same pinhole you see
on a PC's cd player to eject the tray manually.
If there is none, then try this: Open the cover
and find the motor that, when turning, performs
the tray ejection. Then, turn that motor by hand
until the entire tray (or cartridge) is ejected.
Then power up and observe the events." This is
word-for-word exactly as given to me. I still
don't see any pinhole on my unit's exterior and I
did remove the cover once to look around inside
and don't recall seeing any motor(s) accessible
by hand without removing the cd changer assembly.
I guess this suggestion sorta gives us an idea of
what to try as a possible solution..with no
guarantee (of course) it'll work..and depends on
whether or not you feel up to doing a bit of
disassembly on your unit. I'm not sure if I wanna
try that myself..and won't have time until the
weekend in the meantime I'll leave it
up to you to try if you like. If you do and it
works..can you post and advise exactly what you
did? Take care and good luck!

I've just fixed this problem on a mchine - it's very simple. Take the cover off the unit and then look at the left-hand side of the machanism (as viewed from the front of the unit). There's a tower of four cogs under a white plastic snap-on cover. The shaft they're on is supposed to go up&down to select one of the three trays, but on our mech. the funny-shaped wheel had popped off it's fork-shaped thingy. You just have to pop the white cover off & rearrange things... See photo

Dear Sam Moody,

I have the same problem on my PDR W739 but I can't understand exactly how to fix the problem with your last email... Could you please explain me more precisely (sorry, I am French ;))

This worked for me. Take black outside cover off with screws on side and rear (4 black on side) 3 copper on rear.

The white bit takes a bit of force to pop off with a flat headed screwdriver. Once the cogs are in the right place in the black frame. Make sure black frame is engaged with the large white cog to the right of the spindle. Put the plastic back on and then the cover.
