I have a game gear here that has very little sound. I do get sound from the speaker, but it's VERY faint. It's so faint that when you pull it away from your year you can't hear it anymore. The headphones jack is working but also pretty low. I took it apart and didn't see anything immediately wrong. The speaker connection is good and the volume control seems to at least look proper. Is there any common problem like this that I don't know about?
