Sorry to disappoint you, but I only know how to test these cameras. My solution at the time was to send the camera back to the seller for a refund.
If you can’t do that, you may still find a repair shop. I would not recommend attempting to fix a point-and-shoot camera from that era at home, even if you’ve fixed cameras before. These are some of the most complex and intricate devices out there, on par with laptops and smartphones.
