Hey guys,
Ive got a 50" mitsubishi VS-50603(I believe thats the model #.. aint at

home now) projection screen tv which recently would sometimes boot up
display a mostly blue screen.(other colors were showing just it was 90%

blue dominant) Once the tv was powered off for a second or two and
turned back on the blue screen would go away. Then just the other day
the tv stop displaying an image at all upon turn-on. I opened up the
back and found no blown fuses(checked all 3 of them) and noticed that
the crt heaters are not lighting up as well. When I press the power
button the tv makes the "click" sound as if its about to turn on but
stops there. When I power it off I hear a high pitched "draining" sound

which seems to be coming around the flyback though I cant say for
certain. Anyone know what could have gone wrong and where I should
start to troubleshoot? Thanks!

The first thing to do with this set is to look very carefully for coolant
that has leaked onto the boards. These sets are very reliable other than
the coolant leaks and related corrosion.
