you forgot the ones on the convergence board!
if one of the supply voltages was lost that board goes off like july 4th fireworks.
and lets not forget the coolant that leaks,goes cloudy from bugs living in it,or turns to jello.

Oops!! Major omission on my part. Got distracted at lunch today while I was typing my last post. From about 1989 to approx 1994 I did some work for a Magnavox dealer/servicer. Anyone here ever repair a late 80's to early 90's Magnavox rear projection TV? From a reliability standpoint those things had to be the WORST EVER electronics I've worked on. The power supply module and the deflection module in those sets had tons of metal stake feed thru connections to connect the copper traces on the top and bottom sides of the PC board. Just about every one of the feed thru connections would fail. These sets were going out right and left before the warranty ever run out. Some of them that were out of warranty had already been serviced several times. Can you imagine how upset customers were after paying $1,000 to as much as $2,500 for one of these projections sets only to have it break down every time you turned around? The replacement boards weren't cheap either. They sold for around $150 to $175 each. I usually got stuck doing the service calls on these sets, so many times I had to face the wrath of an upset customer. We lost some good customers because of those junky things. After awhile, the owner was giving irate customers the number to Philips headquarters to direct their complaints to. I know Philips ate quite a few of those modules for our customers just to smooth things over. I think it took 2 or 3 years or maybe more before Philips finally redesigned the modules of it's projection TVs to have a single sided circuit board. The Magnavox C6 chassis with the failure of those square blue caps that would burn a hole in the circuit board and also the C6,C7,C8 and C9 chassis that would have a cascade failure in the switch mode power supply were pretty bad too.
