Help with Playstation 3 and my new LG 47" 1080p Model 47LC7DF

I just purchased a LG 47" 1080p Model 47LC7DF and a PS3 40 gig. It is connected with a HDMI cable and I have been experiencing some problems. When I set-up the PS3 to HDMI the menu starts to flicker and flash like crazy. Now when I use the old component cables all is fine. Im not sure also in the 1080p function is being outputted from the PS3 to the LG--ie it may be reverting to a lower resolution. Now when I the blue ray disc actually plays on the PP3 is works pretty darn well and look cool, but not sure if its truely the 1080p I paid for. Is there a problem with ps3 and 1080p output with this TV, or could it just be the cable as the person from Sony Sugested. Basically it is likley to be the cable, the PS3 or the TV?

Thanks
