Black Screen diagnosed as bad video card on logic board
After reading many diagnoses for this, I've opened it up and am looking for led lights. My main prob. right now is,
this is a Late 2006 model MA190LL 2gHz
and I can't find a manual here nor on Apple - none of the ones I find are exactly like mine.
I did get the front off and can see the logic board but not the lights.
Is this a good question?

I think you got the number wrong. A late 2006 17" 2.0 is a MA590LL/A
Apple iMac "Core 2 Duo" 2.0 17-Inch Specs

Yes, it is a typo, I've been looking for the MA590LL but didn't have those next numbers you list. Still, I think maybe there isn't a manual for this one.
So, I am in the front and there are some led lights. Do I need to start over and go to the back?
Right now, I have the screen out, I can see 2 lights lit up but cannot find the SMU reset button. I don't see anything that looks similar to the photo on the Apple page I'm working from http://support.apple.com/kb/TS2094
these instructions say to push this reset button next.

This is an Intel machine, not a G5.
