Why is my MacBook charger not working?

i took out the logic board to clean out the dust from the fan and underneath the logic board because it was getting unusually hot. After putting back the logic board the computer booted up and it is working fine.

however the macsafe charger port now does not work/charge after the operation, and no light comes up on the charger . i have used multiple different charger units but none will work.

any ideas???

Try PRAM reset, this may trigger it back, alternatively make sure you plugged it in from underneath the motherboard! Also check your charger / use another.
