When I plug in the charger, LED on magsafe connector doesn't light up.

AC Charger Information:

Connected: Yes

ID: 0x0000

I Have replaced the battery and the machine still works under the power from the new battery but the LED won’t come on the magsafe charger. Now I have replaced the DC In board and still not charging. the charger works on the other Mac in the house. What could the issue be?
