I recently got a used Sega CD Model 1, and I am having three issues with it:
1. The CD Tray always get caught about 2/3rds of the way in, jiggling it allows it to go all the way in. It DOES eject just fine (from my understanding, most of them that have problems won't open at all).
2. Audio is scratchy.
3. It seems to have issues loading CD-R games, is this normal for a Model 1?
I tried to lookup as many teardown/repair guides and videos as I could to see if I could at least fix the tray getting stuck issue.... but when I opened it, it was nothing like what the guides showed (and yes, I specifically looked for Model 1 guides). None of the gears are in the right place, the optics seem to be made by JVC instead of Sony, and there was a screw in the CD Tray I had to remove in order to get it out. The entire CD drive itself is drastically different from any other guide I have seen.
This is what the drive looks like with the CD Tray removed:

The tray was definitely not fitting correctly though, since even retracted it was clearly preferring to lean on one side instead of be centered.... but I could not find any slots or grooves that it was out of place on, nor anything broken or missing that could be failing holding it correctly.
What model even is this? Any advice on how I can try to address any of these issues?
