See those solder blobs on the PC board? Notice how they go out then taper
back in to get to the solder pads on the boards? Cold solder joints all
over this thing. A good solder joint looks like a little tapered building,
tapering from the end of the lead poking through it and wider at the base
where the solder pad is, and shiny. These blobs aren't soldered. Wriggle
the components around and one of 'em will move the blob on the bottom or
the lead inside the blob.
