Disc drive won't open

CD / DVD and most optical drives - Manual eject by sticking a straightened paperclip in the tiny hole and gently push open.

maybe a disc stuck in the drive? if you pull down outter door of disc drive (unless you can see the front of the disc tray already) there is a tiny hole on front of disc tray, large enough to get a paper clip wire into, that will release the tray and pop it open

Might have a stuck disc. Use a straightened paper clip in small pin hole of the CD drive to manually eject.

Someone is going to have to open the unit and see if they can cycle the disc out by hand or not.

There should ba a tiny hole on the front of the tray cover on the drive.
Switch off, get a paper clip or something about the same thickness and insert it carefully in to the hole, push it in until the tray opens.

Disc have something sticky attached on top (label ,specially rental discs') so when you try to eject disc get stuck on tray of spindle motor.Top cover need to be opened in that case in order to remove disc

Look at the face plate of the CD drive, if it has a small hole located under the tray straighten out a paper cilp and stick it in the hole to preform a manual eject. Remove any disc inside and close it. Now try to open it normally. If it still does not work it is time to buy a new cd drive.

Sounds like there is a problem with the holders on the top of the dvd drive that is supposed to keep the discs in place so it prevents the noises from happening. They wear out after lots of gameplay. Easiest thing to do is to replace the dvd drive because to open it up and replace the holders could cause more damage to the drive.

Take a can of air and blow some onto the laser of the drive so that way you know for sure its not dust or dirt on the laser that is causing it not to read.
After you do that if the drive still won't read any discs then you know the drive is bad and it'll have to be replaced.
