Is the TV actually turning off or the screen going blank?

If the latter I wonder if the resolutions betwwen the PS3 and TV are not set to the same?

Check the HDMI cable.
It could be the TV is losing sync with the PS3 (HDCP issue perhaps)

What are you doing when it turns off? Gaming? Watching movies?
Do you have any other components connected to your TV?

Could be interferance from some electrical swithing going on too possibly.  I had this with satellite TV every time our heat transfer kit thermostat kicked in.  Check the cable with another one first if possible.

Could be a cable problem? What sort of cable is it? Do you have another one to swap it out and test?

Must admit I have had trouble with cheap cables failing and my expencive cables have been fine, everyone keeps saying there's no difference as all digital for picture etc etc, but there must be build quality difference's? 21 orso wires inside one HDMI all soldered correctly to each end, hummmm.

People don't say there's no difference at all, just that with digital it works or it doesn't. There's not a variance in quality with a digital cable, ie "I get better colour reproduction and warmer sound with this HDMI cable over the other one". Of course there's a difference in quality between cheap and expensive cables, but the question is is it worth spending more on expensive cables when the cheap ones work just as well? Probably not.

Sometimes the cheap as cheap ones might not be as robust and could cause issues such as the one mentioned, particularly moving up to 1080p.

Hey, strange coincidence... The 32ex400 display model at my work has been doing very similar things for a while now.
We have it hooked up to a phillips bluray player via HDMI and a few splitters and every so often it will go blank for a few seconds.
I'll be working on saturday and I'm going to have a good look over the setup and swap cables and sources a bit and see if I can find out whats going on.

I've seen some HDMI cables that can do what you are experiencing.
They work fine at lower resolutions like 1080i or 720p but at 1080p the picture cuts out from time to time.
Swapped to a better HDMI cable and problem is gone.

Beg, borrow or steal a higher quality HDMI cable, then you can rule it out.
The next step is to swap out a different PS3, if it keeps doing it - then it's time to take the TV back.

Perhaps something like this could be happening? (I don't know whether to believe the story or not).

Energy saving light bulbs can change TV channels

Cheers,
