/diy/ - Do It Yourself

Hey /diy, I often comment but rarely post. Today I have bought a CD player SL PG460A (Technics) from a used item shop for 20 bucks. Seems to work well in the store but when I plug it on my amplifier there was a problem. The seller is a douchebag who won't take it back. Too bad I have to repair it myself.

So, when I put a CD inside the player the optical pickup glitch randomly later in the song and it is very annoying. I was wondering if you could have any ideas.

I 'm an electronic student so I thought I could go in it by myself but... It's not too easy because I don't know where to start.

On vid you can see the optical pickup doing shit
