Hello, my name is*****'ll be happy to assist you.
Memory cards has nothing to do with the problem in camera as it seems has got ccd imager chip failure, this chip is an electronic device that mounted on end of lens assembly inside camera and converts an image into electronics signals that go to main board of camera fr further processing, memory card is just a storage media to save picture files when you push shutter button on camera to take picture.
Since camera is quite old so it would be hard to get required replacement ccd imager chip and camera will take apart in details to get it replaced so camera tech would charge approx $70 or so as labor if ccd imager chip is still available anywhere, at this point I would recommend to invest repair money on new replacement camera instead of spending it on this old/ obsolete camera.
