Ugh...I just finished setting up my new system and I'm getting distracting bursts of brightness. Its very subtle but very frustrating. I have unplugged just about everything in my house attempting to find the interferance, but haven't found the source. It is not present on my component input when I play a DVD, but if I stop the DVD I can see it against a blue background. Its waves of interferance, but I don't know where it is coming from.
