I know this is an old thread but I came across it while looking for information on the same camera which I just bought in a charity shop. I put in new batteries after determining that the xg 1 won't even fire in B mode without power. Anyway camera still dead so I wiped battery chamber with Ipa. Still dead so a bit worried but with nothing to lose I gave the battery contacts and cover a good scraping with a screwdriver , ipa again batteries back in Mode ( I used 357 batteries, not exactly the right ones but they fit) and hey presto the camera sprang into life! And it's a nice little camera. The shutter isn't too loud or clunky for such a low end model and build quality is pretty good. So if you get a seemingly completely dead one of these it may well just need a good scrub in the battery chamber.
