caylie, the fuse of the Playstation 3 video game console is prone to tripping. When the fuse has blown, your PS3 will no longer function until you replace the fuse. There should be one fuse and two thermal fuses on the inside of your power supply, Fuse F101 (T8AH AC250V) thermal Fuses THP101, THP201 . Check those and replace as needed. Also, check for any leaking or swollen capacitors in your power supply. Again, make sure that you have, and know how to use, a multimeter. It is needed for the trouble shooting. You'll find the guides to work on your PS3 right here. Hope this helps, good luck.
