Hi, I have just picked up my second sony HD projection tv, and am trying to fix it. Ron M. helped me fix my last one, so I'm hoping this forum can be of use again. When I acquired it, it was doing this: http://www.youtube.com/watch?v=OZTLWCsPYZU Which to my uneducated eye looked like a screen bias adjustment issue. So I got it home, turned down the screen bias, and the TV flashes less, and doesn't shut down, but it started smelling nasty. On further inspection, R7324 was starting to burn up. I then tried pulling the blue driver board off the tube, and running the set that way. No excessive current draw, but I hear arcing. At this point i quickly shut the set down, as my last projection damaged a tube by arcing. The arcing happens after a similar amount of time, and in a similar pattern to the blue flashes when the blue board is attached. I'm not sure what to troubleshoot next, so I thought I'd get some guidance from here, since probing about test points isn't really an option unless I have a good plan. Thanks in advance, Ian
