I've never done this but a friend of mine repairs HP printers and has done a few that were repaired that way. I know, it sounds CRAZY!

Interesting. Never heard of the ball grid until I looked it up. Really like the possible repair solution. My wife would say they named it after me and my projects, half baked !
Remember seeing those big chips in there. It would make sense, too. Acted very much like cold solder joints of old. I'll give that a go this weekend.
Great suggestion.
Thanks again.
