iMac G5: Worse Than Before

Image of the machine in Open Firmware showing video glitches present after recapping. I suspect that there are cold solder joints and the video card isn't getting proper power.

Well, I managed to get all the capacitors I previously complained about desoldered and the new parts fitted. However, the iMac G5 now displays video glitches while POSTing, and it never boots past a plain blue screen with an artifacted cursor. As can be seen above, video glitches are also present in Open Firmware.

Looking at this photo (large size here) and seeing what may be some cold solder joints I suspect that some of the caps — specifically those for the video controller / memory — aren’t doing what they are supposed to. This means that I’m going to be taking the machine back apart tonight or tomorrow and attempting to reflow those joints.

I’m disappointed. It really frustrates me when I screw something up.

UPDATE: I think I should probably take a look at the display cable and its connector as well.
