From what I have read in a couple of older posts here, no service manual has even been released for any Zaurus SL model, unfortunately:

Sharp has only released some HW infos on the earliest models, though no schematics:

I hope to be able to put back the old Zaurus wiki online soon, maybe there could be some info about this. It would be also interesting to get in touch with some old Sharp employee or official Sharp repairing services which might have a copy of the manuals, we can host them here.
BTW, not related, but I have found some hires scans of Zaurus related pamphlets and catalogs here:
