The number on the Denon Sanyo one is SF-P101N but as that is on the
plastic of the body rather than a label, there may be a lot of flavours.
The optical unit just carries the laser , the receive photodiode matrix
, and the focus+track coils. Could the track coil polarity be wrong?
2 minutes in could be where the sledge has to definitely have moved as

differentiates the orthogonal coils? A small voltage in each to see if
the lens moves vertically or radially I suppose. Nothing like
heuristics, its not as though the owner is paying for my farting about.
