Is there a reliable company that will fix my ps3, other than sony?

May be...

My ps3 can turn on, and eject and accept disks, however when I turn it on there is no image on my television. I have a standard definition tv. But i tried it on my friends hd tv and it still didn't work. And sony will not fix it because my warranty has expired.

maybe Geek Squad. Sony will fix it without the warranty. You just have to pay $150 fee, I believe.

Have you made sure the cables are plugged in tightly and nothing is loose. Also try holding your finger down on the Power button until you hear three beeps. This will reset the display settings. If you still don't see an image then call Sony and get ready to pay the $150 to have it fixed.
