Wow! A bit of a mess to contend with...
Are you sure you don't have any unseen solder bridges anywhere?
Are you sure you don't have any open traces anywhere?
I see a LOT of little solder balls floating around the circuit board. Any shorts?
Invest in a small brush and some 'rubbing alcohol' and clean up that PCB.
How do you program the PIC? How do you know that you are actually programming the PIC?
Does it read back with the same code you programmed it with?
Have you even considered changing the program to the one I suggested? Or are you still running the same 'one-shot' 'turn the leds on once then turn them off' program?
Do you have a decent cap across Vdd and Vss on the PIC itself?
Is the power supply stable enough? Does it rise to +5v smoothly? Does Vpp come up to +5v before Vdd?
Do you have a 'solderless breadboard' to pull the PIC out of that circuit board and try it elsewhere?
Is the PIC installed in the correct orientation?
