The PS4 was no longer reading discs.
It went well, no issues.
Make sure to tuck back all cords and wires back into their original place or else the parts will not fit back in place. Be sure to use a container so that you do not loose any screws. The torx screws can be a bit hard to remove if you do not have the right one. I bought a set from Lowe's and it didn't work so well. Have to do alot of prying.
