Something very particular to my situation happened. The monitor I was using is from my Dell Optiplex 9030 AIO computer which can be switched to HDMI in mode. Even when I had video I couldn't get audio. When I clicked on the tools to check for exploit my system shut down. After that it no longer...
Just got a ps3 to jailbreak. When I tried to open the tools (whatever it's called) my ps3 beeped and went to black screen. Turning off/recovery mode nothing helps, still black screen. Fat ps3 did all preps new account cleared browser etc. Fallowed "Mr.Mario2011" guide on YouTube...
