Hello & welcome to the forums
If any supplier should happen to have spare parts and modules for the RS1000 (which I think unlikely, in all honesty), they would almost certainly be far more costly than the camera's current value. You'd be better off buying a used example cheaply from an internet auction site like eBay to either replace your camera or use as a donor unit for spares. Then again, if you're intent on repairing, you'd need to diagnose what the problem is... it may not be the lens assembly, but something else entirely.
With these older consumer compact models, you have to weigh up whether it's worth putting any additional money and time into them versus replacing altogether
