Bought June 2009.  In March this year picture started to black out several times a day for about 2-3 seconds each time.  This was fixed by the dealer with a software update.   Same thing has just started again, and am awaiting dealer to check it out.  I'm running HD via Sky.  I know it's not the Sky Box as when I rewind and play the prog it does not have any blackout.

Has anyone had a similar problem?

Thanks Tedwood
