Solved: Newly Built IR Toy V3 not working

Hi,

I hope someone can help me figure out what's wrong and any help will be greatly appreciated.

I got my V3 Ir toy board and quickly populated it. after a day of playing with it in a non-working condition i can tell you, the power LED only turns on for a flash (split second) when you first attach the 5V, the LED never stays on. what's stranger is my PICkit2 see's the MCU, and i can upload the hex, but the tester always returns FA22 as i'm able to see the COM port.

I've reflowed twice, gone over each point with an iron a few times, driving me a bit mad.

Here are some pics,

Any help is welcome!

I just removed all the parts, got brand new parts (measuring each component to double check) and i am STILL having this problem!

Well this is bizarre, after realising my IR emitter diode had an incorrect polarity, the device started working, but there's still no voltage to the power LED.

EDIT: ok ,  i realised it's not an always on LED, feel like an idiot now!
