hello everyone a have a big probleme with my ps4 i teardown my ps4 because a was doing some sticker bomb on the case and when i rebuild the console the eject bouton wont work at all but the power bouton work greats can someone tell my how to fix it please :( Update (10/01/2015) i have this forme at the end http://prntscr.com/8mr06l

There is a small metal tab on the bottom plastic that has to touch a copper pad on the motherboard. If that metal tab was bent or is misaligned it will cause the problem you are having. I’m guessing it’s one of those two things. I would remove the bottom plastic and inspect that metal tab, then make sure it lines up as you put the case back on. I hope this helps!
