does anybody know what the ribbon cables pinout is? I would love to know, so I can hook up some video-in to the tv tuner board, since my good guess is, that the upper part is just transporting or converting the signal it gets from its receiver to a mere video-in signal with LandR audio, since you can also hook up video-in to the tv tuner on the jack. and my other wild guess is, that the board the actual receiver is hooked up to splits up the signal into 8-bit chunks the game gear itself can understand. Please feel free to correct me and give more info, i NEED the pinout, since i got no tools at home to check what the ribbon cable actually is cooking.

A small washer fell out of mine when I was taking it apart. Any idea where it goes?

If it's very thin and small circumference it goes between the antenna and swivel. There may be 2 of them.
