Is anyone writing a manual on Sony CyberShot DSC-H3 repair?

The function (mode) selector dial on my Sony Camera DSC-H3 absorbed the full force and the internal switches were damaged after a fall, and now the camera jumps from one function to another unpredictably. E.g., I set it on automatic mode, and it will jump around to different functions on its own, such as sports (fast shutter) or high sensitivity (low light), manual setting or movie mode. At other times, it will turn on in one mode and I can't switch it to another.

Has anyone started a manual on this excellent camera yet? Has anyone even taken one apart? It would help even if I knew it were very similar to another model, such as the DSC-H2 the manual for which is already in the collection. I'd be happy to write one myself if can get some general guidance such as this.
