I recently bought an old black ops 1 game and when i got online it was very fuzzy i couldn't see the screen. I finally figured out what happened and ill post a tutorial just in case anyone has this same problem. This is what my game looked like

Step 1- Clean your Black Ops 1 disc.
Step 2- Check your audio/ Visual settings in the PS3 Settings
Step 3- Get on Black ops and Go to options then Stereoscopic 3D, TURN IT OFF. Then it will prompt you to reset your game, do that then restart your ps3 and it should work!
I hope this helped!
