Panasonic 3-chip DLP projector

    I bought a two year old Panasonic PT-DW7000U-K which is a 3 chip 1366 x 768
    6000 lumen projector. Anyone familiar with this or similar models?

    Unfortunately a mistake was made in shipping as they shipped with the very
    heavy lens in place. It was noticeably loose on arrival. Opening the
    projector so far as I could tell nothing was actually broken but some
    screws holding parts of the lens mount had worked their way loose. I
    tighted what I could but there are two maybe 3 which I cannot get to
    because of the projector housing. The projector is fully functional aside
    from this.

    The way it's laid out the plastic top of the projector also forms most of
    the sides. The bottom of the projector (also plastic) curves up and forms
    the bottom couple inches of the sides. As far as I can tell there is no
    single chassis inside that would lift out everything. It seems that most
    of the bits and pieces are screwed to the bottom. In the critical optical
    area the TI DLP light engine and the lens mount are attached to a
    substantial metal casting which is in turn attached to the projector
    bottom.

    The screws I want to tighten are on the sides of the lens mount aera but
    far enough down as to be blocked by the part of the bottom that comes up.
    What I'd like to do would be to lift the whole casting and everything it
    holds up a couple inches. Alas while I can undo 3 holddown screws I can
    see there is at least one if not several more I can't see or get to and the
    stuff that is blocking the way...well...like I said, there doesn't appear
    to be any one thing but lots and lots of small parts that would seem to
    have to come out first. The space between screws and cabinet are too small
    for a sideways driver although I will try when I get a chance.

    So here are my options:

    1. Give up and send it off to Panasonic's authorized repair depot (only one
    in the country for this model, they said). Cost would be $130 to diagnose
    and I would guess a couple hundred for the repair and maybe 100 for
    shipping both ways. This is a great projector and not inexpensive but is
    it worth it if it really only needs some screws tightened? Also small risk
    of additional damage in shipping.

    2. Try to figure out the disassembly technique and of course take a chance
    of f---ing up the projector where it doesn't work at all anymore.

    3. What I am leaning towards: Drilling a couple of small access holes
    through the plastic cabinet and tighten the screws through them. I really
    would hate to do that but it seems almost logical to sacrifice the
    perfection of the like-new cabinet for the sake of avoiding either of the
    above. One saving grace would be I think I could make the holes in a spot
    that would be hidden by a warning sticker. I could use some kind of
    plastic filler and then put the sticker back over and it would be
    invisible. Or drill to some particular size for which plastic filler plugs
    are available to make it more tidy.

    Other option is see if Panasonic will supply to you a service manual, of
    course you pay for it, to instruct you how to properly disassemble the case
    to access the lens screws. May actually cost less than the $130 + shipping
    to sent the thing to them??

    Other option is see if Panasonic will supply to you a service manual,
    Yeah that's a good idea. I didn't see one listed online so I didn't think
    it was available to the public but an email confirmed that it was, for
    US$14.63 plus shipping. I'll have it overnighted. I have a feeling that
    even with proper instruction I may not want to chance it, if it has to be
    taken apart in many pieces but we shall see. There's also the possibility
    that there's more needed than tightening screws but I'm keeping my fingers
    crossed on that.
