I know this is an outside chance but, before I order in from China and have to deal with the "random" tax application, I would be silly not to give this a go.

I need to get a new DMD chip for my Optoma HD600X projector. Does anybody know of a projector service centre or DMD chip supplier here in Thailand? I think it will be a long-shot as I know people in England that have to import these themselves too.

Thanks John. I have spoken to them in the past and they are nearly clueless on the extended Optoma range. I will send an e-mail but I remain cautious that I will receive a reply. Thanks for posting though.
