Nothing shows up on the tv

after turning TV on try pressing guie or menu to see if that makes picture come on.

sometimes you need to have the computer off before hooking up such a connection so the video card can identify the screen being used when the computer is first turned on.... also maybe incompatible with the adaptor

Check the video out settings of PS3.

First diconect the wee consoule. Doubel check all your conections to the tv. Make sure everything is hooked up were it should be. When you are sure everyhing is were it should be turn the tv on. if no tv press the source/input button on tv or remote. If there is nothing seriously wrong you should get you tv back. Sorry this was the best i could come up with

does it work if you hook it up to another tv?
maybe the cables went bad?

Have you changed the input on the tv its self. To get it to read the rca jacks.

Hold down the power button until you hear 2 beeps. It should reset the video.

keep ur finger on the off button 4 a min

make sure the cords r not bad

I would suspect bad solder connections on the convergence IC's caused one to short out a blow one or more pico fuses, thus causing the set to go into shutdown so as to stop further damage to the set. The TV will need to be seen by a profesional to confirm or deny this.
