I was in the process of reassembling a Sony CDP-C435 5 disc changer
which had intermittent problems. Sometimes the carousel would just keep spinning. Sometimes the door itself would jam. In any case, it seemed I
had sorted out all those problems and then I decided to remove the main
pc board to check for cold solder joints or aging capacitors. Everything
in that respect checked out OK. When it came to the point of
reinstalling the main board, I noticed there was a problem with the
connector on the main board where the FFC attaches to it from the CD
transport assembly. These photos tell the story:

Does this connector have some sort of movable latch to hold the cable in place? As it stands now, there is no slot to insert the cable and I
can't find any extra pieces on my bench that could presumably be the
missing piece. Either that, or there isn't anything missing and I just
can't figure out how to reattach the cable.

Thanks for your reply

I had run out of ideas until I watched a video of a tech working on a
similar Sony 5 CD changer. I noticed as the camera panned by the main
board that the FFC connector looked EXACTLY like the one I'm fixing.
That confirmed that the connector wasn't broken. After giving up looking
with my magnifying glass at the top of the connector (CN401) I turned
the pc board upside down, foil side up, and saw there was a very small
amount of overhang at the edge of the board where you could see the slot
where the FFC could be inserted. I had never seen any connector like
this before. I made a white line marking on the photo showing where the
FFC could be inserted.
