Roland JV880 service docs/schematics?

Post by creatorlars » Wed Jan 13, 2010 2:09 am

Hi everyone,

I'm trying to fix two Roland JV880 rack modules for a friend -- they are both not powering up after a European tour. Opening them up confirms the PSUs aren't producing output voltages and I can't see any visible fuses. I haven't had any luck finding service docs/schematics for this unit through google searches or roland's service download area. Anybody got them?

Cheers and thanks in advance for any help.

I've got a copy but yeah check the fuse and make sure the caps are not fried...not sure how the psu is designed but also check any and all voltage regulators.
Hope this helps,
