Roland JX-8P for repair or parts - $250

1234567

condition: fair
make / manufacturer: Roland
model name / number: JX-8P

Selling my Roland JX-8P polyphonic synthesizer, it's in functional condition but it really needs some service and tlc I just don't have the time, interest, or resources to invest in repairing this synth.
Here's what works: All the sliders, knobs and functions of the synth engine are fully functional and there's no noise or scratchiness from slider adjustments. The after touch is still functional! (Pretty rare for a JX-8P.) The pitch bender works perfectly and all audio and midi ports work fine to my knowledge as I've used a midi controller to play it in the past.

Now here's what's not working: The lcd display is pretty much non-functional at this point. It's very fidgety but it will occasionally illuminate text when you apply pressure to certain spots on the synth leading me to believe it is likely not an issue with an opening in the circuit and more contact related. I haven't taken the operation boards off of the front panel to even take a look so I don't know much. Aside from the display issue there's two other issues I know of, the keys are a bit wonky but I've got most of them working perfectly after shooting the contacts with contact cleaner. However a few of them have an occasional issue where they continue to trigger after you stop depressing the key, hitting the key multiple times afterward will cause it to go back to normal for the most part. I haven't actually done anything to disassemble the keyboard itself and really get in there to clean up the contacts but judging from how most have been fixed already it should just be a matter of a good deep clean or replacement. The flat cable that allows you to interface the insertable cartridges data with the patch memory of the synth isn't aligned and is way out of place, it's pretty much useless so the cable needs to be replaced as you can't solder it into place without melting the cable.
