Answer to: When I turn on the camera I see nothing?The lens iris assembly is probably sticking closed. Sometimes oil migrates onto the iris assembly from the zoom mechanism in the lens, causing the iris blades to stick together.
Answer to: "No Memory Card Error" What next?One of the contact pins are probably bent or mashed in. The way SD card slots are soldered to the PCB makes it nearly impossible to replace. Machines, not man solders this stuff together when it's made. Your best bet is to get a good main PCB from a junker SD1000 camera on eBay.
