I just won a very clean game gear off ebay! Only issue it has is the sound. Ive read around about sound issues and it seems to be a capacitor that goes bad, but the sympoms for it are not what Im having. From what I have read, the capacitor causes no sound at all or very weak sound. My sound works perfectly. Sounds good and gets loud. But in the background there is a constant humming/buzzing sound. It starts right when I turn it on and stays on the whole time. Any ideas?
