I have a Sony TC-WR801ES dual tape deck that recently developed a
problem.When I put a tape in it makes strange noises like when you try to
rewind after it's already at the beginning. It does this for three seconds
then quits. It fails to FF, REW, play, or eject the tape. I took it apart
and was able to remove the tape. However, I tried sticking a sacrificial
tape in the other deck and it does the same thing. Since both "died" at the
same time, I'm suspecting an electrical problem on the main board, and not
a mechanical problem. Has anyone seen anything like this?

thanks
Adam
