I picked up an INTV II yesterday at a flea market. My excitement to try it out quickly died when I attempted to power it up... I was met with absolutely no power light. Not even a flicker.

Everything looks fine cosmetically. There are no rips or damage to the power cable. The connector fits tightly in the system. It's an official Mattel power supply... I'm at a loss for what to try next. Believe it or not I've never had a problem like this with any system. Anyone got a suggestion of what to check?
