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 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 0 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.

  1. 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.

  2. 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.

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.
