This is a common problem on the slim PS2. I'm assuming you checked your cable to the TV and made sure the TV is set to the correct input. Normally, what happens is a fuse (sometimes more than one fuse) blows on the main circuit board and causes no video. We do this repair often in our shop. But I doubt you can take apart your unit and locate, test and replace the open fuse. The price for fixing this problem is cheap. AZtech at aol.com
