Hi,

When you replaced the screen there might be a cable that had been disconnected or got loose. I would retrace the steps you did with your PC and make sure everything is seated properly. If it's not working fine with just the AC adapter and the battery is removed that means it could be the AC adapter port or cable that connects it to the motherboard. Lastly, try another AC adapter that has the same voltage and see if it will work.
