Default CCM Woes

My '91 has an intermittent CCM. It is out and connected, leaning up against the firewall. Sometimes it works fine, other times it goes to sleep (no interior lights, blank dash). If I tap on one corner of the circuit board (I took the board out of the case) it usually comes back to life... for a while. Examined the board closely but no obvious solder defects. Talked with Cardone about re-building it but they couldn't give me straight answers. Anyone had CCM issues and how'd you solve them?

Check this out. I don't have any experience with CCM's so I wouldn't know how to start fixing it.
