    Hello all,

    I'm having some troubles with my Sega CD Model 2.
    It works but the problem is with the sound, it's really scratchy. The sound in the start-up screen is fine.
    Here is a video the show you the problem:


    I'm not that very good in electronics. I watch some youtube video's and do some soldering with what I see.
    So my real problem here is how do I go about and troubleshoot this?
    How can I figure out what the problem might be and what do I need to replace perhaps?

    Here is some extra info on the Sega CD:
