playstation 4 log out cd
This is a common problem with PS4's. There are several things that you can try in order to get it working. If either of these work they probably won't work for a long period of time but they might.
1) You can try turning it up on it's side. This usually won't work, but it does sometimes...it's worth a try.
2) Another thing to try is hitting it against your knee or the floor. Not hard enough to break anything (obviously!) but enough to give it a bit of a jar. This method probably works more than the first method, but is not a sure thing either.
These are the first things to try. If neither of them work then you'll probably have to take it to a repair shop or send it in to one.
I hope this helps. Good luck
