Reflowing the solder points is also something I may do. I have the relevant equipment (a Quick 861DW and a simpler vacuum desoldering gun).

I also have a microscope, camera, monitor, B&K Precision 393 and all the rest of it, but I was planning to spend two years learning how to do all this stuff before actually doing repairs for people. I've ended up kinda in the drink before knowing how to swim. :} The microscope, camera, power strip and other stuff are not yet setup. I also have a large ultrasonic tank but not yet a drying oven or somesuch.

Done lots of XMAP readings last night, two more ICs to do just now, then I can compare. After that I'll go over the static RAM ICs.

There aren't any power issues that I'm aware of, that's all handled elsewhere (so far I've not found any ground shorts); I figure DC comes to the board via a ribbon cable from the PSU (the same cable connects to both boards).
