I know this may sound strange after all this time but-- i think Ive located the turning ( dichroic) It wasnt quite where I was expecting it ,it was smaller than I was expecting , It was dirty and the coating reduced its reflectivity even further.So it wasnt until I shone the beam from a dinky little led bulb inspection light i've knocked up in below the focus lens that I caught a glimpse of it.Any way Ive cleaned it with a sort of mini cotton bud made with a cocktail stick and half the head of a normal cotton bud.

But it still refuses to recognise a CD.!!
I am still of a mind that there is maybe a(collimating?) lens missing from between focus lens and the newly discovered Dichroic. This is all of purely academic interest as it came as part of a batch I bought and it owes me nothing ,except the fun of making it work.

Hi baggins,
It wouldn't surprise me if "things" fell out of the head. The lens in the Pioneer units used to fall out often. Carefully gluing them back in saved many customers the cost of a new one.

Cleaning the mirror, use only compressed air or possibly fluid followed by air. It doesn't take much to move them out of position sometimes.

There seems to be a cup shaped recess below the focus assy. which has no purpose other than to maybe hold something.Were the panasonic lenses spherical on their lower surface?

Hi baggins,
Sorry, I couldn't tell you. Is it Mitsumi or Matsushita?

Hi baggins,
Ahhh, those were convex on the outside, concave on the inside with a mounting lip.

The lens was fitted to the focus / tracking assembly. The entire head was mounted up side down with a theramally sensitive glue.

Let's play ... what happens next?

Sadly, yes. It's also a valid question with a rather obvious answer. What would you think is going to be the result of this situation?
