A1278 MacBook Pro still not charging after changing MagSafe port

So I have an A1278 13” MacBook Pro (2012) that wouldn’t charge. Whenever i plugged the charger to the MagSafe, the light wouldn’t turn on on the charger. Checked the battery life indicator button, in still turned on (blinking red) so i assumed it wasn’t a battery problem and figured it was the charging port itself. I just replaced the port, however, and still no charging. Don’t know where to go from here. Any help is appreciated!
