I'm sure there is someone who can help. Unfortunately, the card reader is a fairly complex setup having its own ROM and interacting with a host calculator, so anything aside from a mechanical problem or a dud capacitor may prove to be a difficult fault-finding task requiring some test gear like an oscilloscope and some knowledge of its operation. I have to admit, I tried and failed to repair one.
