Having looked around a bit, and making some phone calls, your best bet may be to hunt down a used/broken model that is the same or similar, and then gut it for the parts you need. This, however, may be more time and effort than you want to spend, and the money dumped into that endeavor may be better spent on a far more modern body.
In the world of digital point-and-shoot cameras -- note "P&S", not "digital cameras" in general, that does NOT apply to DSLRs --
the 3-year-old 2006 P&S Sony is so ancient that many would find it unusable. It will easily lack the ability to shoot cleanly in low light, clarity of glass/sensor combo, etc. There have been many accomplishments in sensor tech since that camera was developed.
Replacing it might be the best option.
I actually have an excellent like-new Sony P&S from 2006 too, very similar to yours, a gift, but I don't even use it. I should probably eBay
it, as they sell for about $100-150 on there.
