Does Anyone Have This Problem With The Ps3?

[TCX559]

I have a minor problem with my 40 gb PS3 from time to time. When I load the blu ray it works...but sometimes it starts to flicker as soon as it starts to play (meaning right when the disc starts) over and over every 10 to 20 seconds. When the screen flickers it makes this "click" sound and the picture and audio disappears for a split second than comes back on. To make it go away I usually exit the blu ray menu back to the PS3 menu and restart the blu ray again or turn the PS3 on and off again. It's very annoying and it happens probably after every 3 blu rays that I watch. Does anyone else have this problem?
