Hi,

I'm surprised you had any brightness at all with 10 K reisitors; and connecting your LEDs without resistors is probably the only reason you're seeing these results, besides potentially damaging the LEDs, or the pic, or both; use 1 K (or 470 ohms for a brighter display) resistors instead, and that should make your PCBs behave like the breadboard version did.

Regards,
