Le ditto. I'm running out of ideas. What you describe sounds a lot like a power problem; i.e., a short or some other sort of drain. You're sure your batteries are fresh?
Are the resistor networks all in the right way? Your caps and chips all look right. There's not much else to go wrong. Are the LEDs all in the right way? Sometimes it's hard to tell just by looking for the flat side on the lens. But you can see the diode carrier inside the lens. Make sure they're all lined up the same way (and the same way as the boards that work).
Dunno. Grabbing at straws.
