If you hear repeated knocks, then it is a misaligned header and you can use a plastic screwdriver to fix (it is existing a program to help the operation).
If you don't hear the reset knocks during attempt to read, probably the header is fault or some other electronic component. In this case you can substitute the whole mechanism from a 1541.
Last case is the cartridge socket fault, since it has ICs inside. This case is the worse one, because the spare components are difficult to find and to unsolder.
Let us upadate.
