Right..so for those that might not know, I've recapped quite a bit over the years. Started off with arcade monitors, and then eventually to consoles like the Genesis, TurboDUO..etc. And this weekend I decided I would give my model 1 Sega CD a recap job.
The basic kit includes all you need from Console5.com. And nothing is terribly difficult to get to to actually do the work.
I do advised that in the case of the model 1 Sega CD that it be done, if for no other reason, than the main CD logic interface to genesis board has many SMD caps on it and in the case of my Sega CD these were all starting to leak and I was able to remove most of them with my bare hands and hardly any force required! Again, they were apparently starting to leak, so it was a good thing I decided to do this.
That being said, while the task of recapping the audio and main logic board were easy enough. The CD mech and laser assembly...is the one item I advise you to NOT TOUCH! The kits included caps for either the JVC or Sony CD mechs as well. But I was warned about doing this and didn't heed that apparently.
So here is the problem with recapping the laser mech. First the caps themselves depending on the CD model are kinda up in the mech so you have to be careful about that. Also the caps only solder from the bottom side of the board so that shouldn't be a problem. The problem is that recapping the thing will change things electrically on the CD mech. As a result the CD laser has to be re-tuned to compensate and this is where problems arise. In my case I couldn't even get to a point to try and tune the laser because it appears the new caps were allowing more current to flow to the laser head. As a result the laser actually burned out pretty much as soon as I powered everything on. And yes I checked the polarity of the caps and values. The only difference in the caps of the new vs the old was voltage as the larger caps being 330uf were only 16v and 6.3v originally and the replacements are 330uf 25v caps. But I can't imagine that being a problem. Anyway, only but luck did I have a spare Sega CD model 1 assembly that has a broken tray mech. But the laser assembly was good so I was able to swap them out and it was good to go again.
So you should recap the rest of the stuff..but for the love of everything you hold sacred! Do NOT touch the caps on the main CD drive and Laser mech. In fact the originals on the Sony were Nichicons and likely didn't need to be replaced anyway.
