This seems like some sort of power fluctuation to me but I have no idea how to fix it or work on my TV.
Silo ... the blue flash is definitely NOT somewhere in the Blue CRT. It's on the low-voltage power supply board (the first board where the power line comes into the back of the set).
Pioneer's stock advice is to replace as many expensive boards as possible. They are not interested in fixing the problem, at least your problem. They seem more interested in re-selling us the sets one piece at a time.
So far several of us have had success with service techs (non-Pioneer authorized) who were willing to listen to us and really look at that low-voltage power supply board. Once they resoldered the connections the blue flash went away. In my case the tech also replaced a capacitor.
I've contacted Pioneer's complaint department multiple times. I talked to a supervisor there for over 30 minutes the last time I called. His job evidently is to stonewall non-warranty customers and make sure we don't insult his dignity. He told me Pioneer's priority was to maintain good relations with their service centers over good relations with their customers. I can see why, how else are they going to keep the high priced, unnecessary replacement parts shipping to ignorant customers such as ourselves?
I've had it with Pioneer and their authorized service people. I found a place here in Dallas that will fix a board at the component level rather than start replacing the guts of the set willy nilly. My suggestion to you is to do the same where you are at. If you can't get that kind of service out of the company that picked up your set, find another. There's no sense in paying good money for replacement parts that aren't going to fix the problem.
The more I hear from people in the situation we are in, the more I have come to believe my original investment in Pioneer gear was a mistake. It's a mistake I will never again make.
Just replaced my Pioneer DVD player with a Samsung. Pioneer's short-sighted policy of screw the customer will come back to bite them on the rear end.
