PS3 A/V Cable Problems

Ok, one day (yesterday)my PS3 A/V cable stopped giving me video. Both audio parts of the A/V cable worked fine. I bought a new cable...same thing. I'm getting audio, but no video. This has lead me to believe that it is the actual A/V port on the PS3 making the problems. This has me freaking out of my mind! If I'm wrong, and anyone has a solution to this problem, please, HELP ME!

P.S. I have yet to call Tech Support, as I have yet to find a TS number. If you have Sony's TS number, or a link to a TS website, that would also be much appreciated.

Sony's number is 1-800-345-SONY

Thanks for the suggestions...but...nothing worked. I have come to believe that there is a problem with the A/V port itself. How would I go about fixing this...? Should invest in an HDMI cable?

Have you tried the A/V reset? with the PS3's power off hold down the power button until you hear a second beep and it resets it.Also you could resetting the system back to factory defaults in XMB system settings.

If all fails call SCEA Sony Computer Entertainment of America. Just google it to find out their number.
