Sony forum: Peculiar Video problem with my Sony 46EX600 -- please assist

I have a Sony Bravia - 46 inch LED (LCD)?--46EX600

I was using it fine yesterday with my HD cables. Then today neither my Television with Cable Comcast Box -- or Play station three would work -- seperate HD cables. I tried using different cables and problem persisted -- I reset my tv -- problem persisted -- i tried to update -- but my tv was already updated to newest---

So I tried the Red - White - Yellow audio/video cables --- now only the audio works...

So I tried my Wii with its own --- Red White Yellow -- it works fully operational sound and video.

I bought a new Red White yellow to see if it was just my current cable that was broken-- but It is still just simply audio that is working. while the Wii is still working fully functional Audio and Video ---

I also tried component green blue red cables -- they didnt work either.



and now as I have been typing and searching forums the TV just shut off on its own while Ive just been playing the audio with the Red White Yellow cables --- happen again?? To be continued...
