I moved my PS3 the day before yesterday to a friend's house for a party. Today, I set it up at my home. And to my ****ing shock, the PS3 could power on. But nothing showed up at the screen. I tried again. Just a flash when I turn it on, and then a horrible black screen that you would dread if you had a $599 PS3. Because my TV is old, I decided to go set it up on my other TV. It still didn't work. Please... what could be wrong? I have an SDTV, and my cable is white, red, and yellow composite.
