What could be damaged when power button doesn't work?
My iPhone 3G fell to the ground and after that the power button fails switching standby and power on/off. The button clicks like before the failure.
I followed all steps from your repair guides to open the case until I found and released the power button. The real switch inside is clicking if pressed but the ribbon cable connected to it seems to have a small scratch at one side ... maybe the wiring inside the ribbon is cut?!
What other reasons are possible that let the power button fail? And if the wiring really is broken, is it replacable?

Well the other functions on that ribbon cable are the headphone jack, vibrate switch and volume buttons. Test the functionality of those and see what you get. If they don't work either, it's possible that connector #5 just got lose or came off the board. If they do work then it's likely the ribbon cable needs to be replaced. If so, it can be difficult, but more so because it's tedious so just be careful with it. Good luck.
yes the cable would be replaceable, but how should it get scratched inside the phone ?
i agree with jarrett. check the connector. and be really careful.
it could really get pricey when you kill something inside the iphone.
and before you're getting into bigger trouble - let it be & ask for help.
