Fixing old solder joints on Radio Shack Robie Junior

Robie Junior Main Board

When we got our Robie Junior, cosmetically, he looked great; however, once we put the batteries in, he seemed to have many issues.
Luckily, once we opened him up, the issues were apparent. A few of the solder joints had broken free over the years, so we only had to re-solder them to get him back up and running.

You'll need a Philips head screwdriver, a soldering iron, and some solder to do this type of repair. The entire process is relatively quick and should only take 15 - 30 minutes to complete, depending on the number or re-solder repairs. This walkthrough covers the lower mainboard. Any other repairs will be similar.

The process is similar for the following robots:
TOMY Omni Jr. 5410, TOMY Omnibot Jr. "Charmmy" and, Radio Shack Robie Junior - 1986 (Cat. No. 60-2397A)
