My Call of duty world at war has a black screen at startup. I searched the threads and yielded the answer: Just use the ps3 in retail mode with the original disk and do the game update. Turn the ps3 off and back on in jailbreak mode, load the game.
I still get the black screen at startup. I believe Modern warfare 2 does the same thing.
Any help you can provide would be great.
Thanks for your valuble time.
