Sega CD Model 1 Problems

[Zork]

Just bought one for about $5, but it's having some issues.
It powers on, and I throw in a game. It starts to load for second and this spits my game back out. I'm assuming its the laser right? Should I clean it?
Also, how do I even open it? I got all the screws out and I'm a bit puzzled on how to open it...
Thanks a ton guys.

Update: Got the thing open, didn't notice 2 screws
Should I try cleaning the laser? and how do i do this?

Cotton bud (Q-tip) with, well I use Methylated spirits, I think folk in America use iso-alcohol stuff.

If that doesn't work you may be up for a new laser.

It might have to do with the disc tray. I had that problem before too.

Try HERE to see if that might help. It's similar to what I ended up doing on mine.

Thanks guys!
Yeah, I used the q tip on the lens and it worked good.
But then the motor was making this weird sound, so i just pushed the gear...
Started working great!
$5 Sega CD! Awesome!
