Hi everyone. After months of deliberating, I'm just on the verge of buying this TV. I want a large screen TV that looks good, performs better than a CRT Rear Pro, but won't show me rainbows often seen on a DLP set. My only concerns are about the juddering picture associated with this set. Does the service menu fix which I;ve seen in the forum actually cure it for good? Is it easy to do yourself or should I leave it for the engineer to sort out? I'm scared to death of entering the service menu in case i cock up!
