Today managed to fix my Cyrus CD6SE. A bit of a saga....
It started skipping a few months ago, so I got a new laser unit off eBay. A couple of weeks ago, it would not even read a disc, so I thought it was time to swap it out. That turned out a bit tricky, even with some details on here from a while back and additional googling. In my ham-fistedness, I somehow managed to damage some contacts on the end of the FFC ribbon cable. Found a replacement on Farnell for not much, but was plus £10 handling fee, so ordered one off eBay from China for £2.39 all in for a 24 way 0.5 pitch x 150mm long, about an inch longer than the original. But on removing the other end of the FFC, as I released the clamp on the connector, I must have used a bit too much force (or Cyrus's SMT soldering is not up to much). So the connector departed from the board, so more grief. Luckily, I work somewhere where we do a lot of soldering, so I got a colleague who is an aerospace J-Std soldering trainer to fix it. Was even a bit tricky for him being very fine pitch, but he managed it even though the tip of the iron was wider than the pitch of the contacts.
So now all back together and working. Spent ages trying to get the alignment right. Seems it still needs a small tweak, as I just heard a short stutter, but it's nearly there!
