I have an interesting situation: two AG-5700 VCRs with the identical problem--the tape will not get threaded. The cassette gets ejected a second or two after it gets seated. I think this is a timing problem, possibly because the gearing is off by a tooth or two.
I know that the cassette basket needs to be "spring-loaded" and I have adjusted it several times. Although it looks right, the problem persists. I have seen the markings on the gear that interacts with the mode switch, but I must still be doing something wrong in getting the proper alignment to get the timing right.
Here is my question: is there something I can try before sending these out for service? If so, I sure would appreciate your suggestions.
