I have a Sega CD Model 2 with the Optima 6 laser. It works fine with the exception of not being able to read some games. Sewer Shark and most other Sony Imagesoft games will read but others like Sonic CD will not. My guess is that the laser is worn out, so I purchased a new one to replace it with. After removing the solder blob and installing the new laser, the disc isn't spinning up. The laser moves into position, but then the disc never spins and I end up getting a 'No Disc' message.

I've actually made two passes at removing the solder from the blob area, the second time after acquiring soldering wick. But it still won't spin up with the replacement laser. I'm wondering if I might've damaged the board trying to remove the solder, as it does look scorched but the traces appear to be intact.

Is this laser salvageable?
