hmm confusing but try turning your ps3 off at the wall give it 5mins and try again if nothing happens try it on another tv

turn power switch on in the back. red light on in the front, hold the power button until system turns back off. this resets all hardware settings. if this doesn't work and the system is ok (green light) then you have a connection problem to the tv

is it just a black screen or is it in the menu screen

When tv and ps3 backswitch turned on hold down the front power button when off until the ps3 has done a double beep after the intitial beep and wait for a max of 1 min and initial set up screen should appear

After the system boots up, hold your finger down on the metal spot where you normally turn it on. it'll completely reset all settings & hopefully set to the proper video output.

Read this very carefully. Turn off your ps3 from the back. Then turn it back on wait unit the light is red. Turn on the system through the front keep holding the power on. You will hear a beep one time that just tell you that the ps3 is powering on keep holding the button until you hear the second beep this will rest your video setting. If that dosnt work call me at sony

ok a long shot but i did read somewere that if u hold down the power button for 10 seconds it detects or calibrates to the current TV that is connected its worth a try if nothing else, if this didnt help sorry but if it did enjoy :)

P.S. i dont know if the console needs to already be running to do this.

Hello. There are a few causes for this. I will list acouple solutions for you.

1. Reset the Video Output Settings. While the PLAYSTATION 3 system is in standby mode (red light on the front of the system), hold down the touch-sensitive On/Off button on the front of the system until the system goes into standby mode again . (So the light cycle would go from: red light to --> green light --> then back to red light) This will ensure that you have held down the On/Off button long enough to reset the Video Output Settings. Once you turn it back on, it should work fine.
2. If option 1 does not work call Sony because the video out chip has blown or come unsoldered.

I hope this helps. Good luck to you.
