Subject: [AH] Jupiter 8 Repair Help


Hi,

I recently bought a Jupiter 8 that got damaged quite a bit in transit. It
seems to be not the analog part of the keyboard but the digital interface
that is problematic. Many of the switches and buttons are not working.
Patches can change but the switches for the most part do nothing. The patch
buttons and some of the other buttons (unison, etc) work only when you push
down on them very firmly. Also a few of the keys are not working across the
entire range of the keyboard...and diff ones do not work for diff
patches.....for ea octave the same keys don't work and this translates to
the next octave. UPS is not going to pay because the shipper packed it
horribly so I am going to need to send this out to someone. I have opened
it up and checked all the ribbon cable connections and all the connections
going into the digital interface boards (all connections period)and all are
intact and seated firmly. Anyone have any ideas as to what could be wrong
and the prognosis of being able to get the proper parts and/or someone that
is good that can fix it. I am in Orlando, FL. I do not have a tech I feel
comfortable with here. Any help would be greatly appreciated.

Hi, Kurt- Ken here! Sound like your JP might have some connectors inside
they machine come away- open up the synth and check all connectors are in
perfect contact- its worth actually removing connectors and putting them
back on...engages connectivity again- also, some chipps that are seated in
chip holders can move to, but be careful for anti-static reasons if you do
decide to move them in/out....
Regards, Ken

Man, does that ever blow, especially with such a good (and internally
complex) instrument. Well, I'm guessing you know how to pack way better
than the seller, which you may have to do to get it to anyone good.

My recs:

Kevin Lightner, Los Angeles. ex-Roland tech from their JP-8 period.

Rogue Music, NYC. Some very unflattering digital ink has been spilled about
these guys' tech, but he did a fine job on my JP-8 a bunch of years ago.

Expert Audio Repair Service (EARS), NYC. Rehabbed an AHer's PPG Wave 2.2
some time back, JP-8 shouldn't be daunting for them.

DBM Technical Services, NYC. Haven't used them.

Davidson Electronics, Plainview, NY. Nice calibration/svc. on my (former)
Crumar Spirit, JP-8 should be a doddle.

Call 'em, get their labor rates, find out if they (still) do JP-8s.

Any other suggestions for folks closer to Kurt?

Best 'o luck on this, it's a beauty when in working order...
