How do I get the disk out of my malfunctioning PS3?

Solution 1:

Check out the guides on iFixIt.com

The first screw is a T10 Security Torx screw, but a normal T10 Torx screwdriver should remove it. Honestly if you can get the screw out it's not super vital to get it back in so using a flathead and stripping it a bit whilst you remove it isn't too big of an issue.

If you have a heat gun and thermal paste try reflowing the cpu/gpu. You can probably get it working long enough to get your disc out, and maybe even back up your saves.

If not, just follow the tear down guide until you can get the disc drive out. The disc drive isn't too hard to disassemble, and you probably aren't too worried about getting it back together.

Solution 2:

Have you tried holding down the eject button for 10 seconds? This will supposedly force eject any disk inside.

Also, according to a post in this thread, if you have a model of PS3 that allows fan test mode, try turning off the PS3 via the switch in the back, and turning it on while holding the eject button. It apparently runs a fan test and will eject the disk inside.
