My guess would be that either your firmware got messed up on a recent update, or you set it to a display resolution your TV set isn't capable of handling. Check the manual and online to see if there's some method to reset the console back to factory defaults. If that doesn't work, make a warranty claim on it.
Everytime i turn on my ps3 the screen is black no matter which video output i hook it up to just black. I tried the "two beep" method by holding down the power button for 5 seconds and waiting for two beeps, still nothing. If i hold down the ps button on the controller i get the controller menu. Anybody have any ideas why this happened and any advice. Thanks
