Sorry Mark I don't have any clue.
But for reference I will add a tag for future reference.
I too have a BS3200, one of the first that came out.
I don't think it is related to your problem, but mine is chip and software updated.
Now mine is sw 1.9 [Beware: With the chip update you will loose your CD names!!]
The update was due to RANDOM error on the green section.
It shuffled only the first 7 recorded CD's.
