Gutted - after all the hard work trying to sort the blue wear out, I finally got round to setting the 701s up at home last night. Through the line doubler it was looking excellent - did a convergence settled down and watched some tv on it. Was generally very chuffed that the old blue wear pattern was barely noticeable. I was just thinking about where to ceiling mount it and lent (not hard) on the top above the blue tube. I heard a spark and the blue tube went way bright, sucking all the light out of the other tubes and unsurprisingly the pj shut off. It now does this everytime it turns on. I've tried swapping the blue and green sockets and this moved the problem to the green tube, so I'd guess the tubes are ok? Any ideas on what to try - I've got some spare boards I can swap.
