ps3 problem

[11logan]

I have a 60 gig PS3 outputing through component cables.
The problem im having is that everytime the screen goes white i lose picture/audio signal while in 720 or higher resolutions (while Gaming or blue ray or upscaled dvd's) for the duration of the white sequence.

if i knock thr output down to the 480 prob goes away.

my brother also has a ps3 60 gig and has the same problem while viewing through component

i have tried with several different TV's to the same effect. (Including one samsung one sharp one panasonic and two different sony's)
also tried a couple brands of component cables

any
suggestions

and please dont say hdmi as my hdmi inputs are in use and id prefer to go component
