Here's an update... I cracked it open... 1 of the IC's was cocked a pretty good bit out of its socket. Even when I pushed it in and checked the rest of them, STILL no joy. I left it on for 10 or 15 minutes, none of the IC's got hot, so I don't think any of them are bad. I even tried a different power supply I already had, and still nothing.

Any ideas?
