Well, someone who shall remain unnamed dropped a screwdriver into the open case of my brand-new dual 2.5GHz G5 tower. The tip caught on the surface mount transistor (SOT-23) you see below and gravity and inertia had their way with it. Of course, as Murphy would dictate, this was a critical part; the machine would boot, but the video quit working. Tipping the machine upside down yielded a very small transistor that soon became very lost in a sea of gray carpet.
After I finally found it, the next step was to determine where it came from...
Below, you can see where on the board it came from. If you can't see it immediately, scroll further down...
What made matters worse was the fact that the base lead, the one you can't see in the top photo, had snapped off at the edge of the black plastic case...
Fortunately, using a little silver solder, flux, and my trusty butane-powered 10-60 watt soldering iron, I was able to solder the two still good leads back in place. Then I dribbled a small blob of solder next to the broken stub of a lead, and let it cool. I put it back into the machine and fired it up and somewhat to my surprise, it worked! Yay! I saved a couple hundred bucks for a new video card. (It's just the ATI radeon 9600 that came with the machine, but still!)
