Built-in iSight stops working on iMac--try re-setting SMU

Question

I spent about two hours trying to figure out why my built-in iSight stopped working--all of a sudden it would show only a green screen in Photo Booth, black in iChat and not at all in iVideoHD, and not really register as available. It did show up in the Apple profiler of USB devices, and also, it would work in a non-apple program, iVisit. I did not install an HP printer, as another thread user commented on. I read about resetting the SMU in an Apple discussion and also in this forum, so I shut down the computer, pulled the power and everything else plugged into the computer and waited a minute, then plugged the computer back in and turned it on, then finally plugged back in my devices including keyboard and mouse (that was Apple's instructions). Vioala! iSight works again.

Hi,
For Others
As a Note on this some G5s are prone to not having the System Preferences > Displays set to Millions.
There is no direct evidence that it effects other computers but do check if your is still set to Millions and is not being commanded by a games app or something else to display less Colours.
