Introduction

What you need

  • Remove 2 3.8mm gamebit screws
  • Lift rear tuner shell away from unit

Step 2

              Remove Tint Wheel
  • Before we can remove the motherboard the tint wheel needs to be removed
  • A peek on the inside reveals 2 small retaining clips. Simply apply some pressure on the clips with a needle nose tweezer
  • When reinstalling the tint wheel simply align the retaining clips with the holes and press back into place
  • Remove the motherboard from the unit

Step 3

              Remove PCBs
  • When removing the front shell be careful not to lose the frequency switch button located on top of the device
  • If it makes your repair easier you can separate the two PCBs by gently pulling the ribbon out of its connector. This is a friction fit cable

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.
