Hi all,
I've been looking around for info on this, but I haven't had any luck. Thanks in advance.
The system is a model 1 Sega CD that I got out of a Goodwill a few years ago. The only thing it did have with it was the metal plate that fits between the Genesis and the CD. The Genesis is an model 1 too. It worked fine when I got it.
When I got it out last (about 2 months ago) the audio in the game was skipping, so I cleaned it, and everything worked fine until a couple of days ago.
Now when I turn it on, there's a weird plusing/humming that happens on the splash screen as well as in the game. At first it sounded like feedback, but now it sounds more like the sound from the left or right channel is garbled. Spoken dialogue sounds tinny and scratchy. It also seems to happen in waves (ie. the background music will go on and then get replaced by the hum and then go back to music.) It's also definiately getting worse.
I switched the Genesis with my other one, and the problem's still there. Also the Genesis games don't have this problem.
I've opened it up, and it was pretty clean and I didn't see any obvious damage. I dusted it with some canned air, and cleaned up the contacts. Didn't help.
So, any idea what might be wrong with it, and how difficult it might be to fix it? I can solder a little, and am not afraid of opening these guys up (I've put a mod-chip and a region switch in a Saturn before), but I'm not an expert.
If the problem is beyond me, is the system somebody else would want for parts, or should I send it to the plastic graveyard?
Thanks again
