Just wanted to say thanks for the info and help on my old projection set. I
grabbed a set of boards from eBay, put the power supply in, replaced the crt
coupling fluid in the blue CRT (it was the color of beer) and got the set
going again.

Who knows how long it will keep going however I'm having fun and learning a
lot. I did remove the CRT and followed the replacement instructions in the
service manual. Very easy; place on lens housing on an old towel, tilt
assembly to fill expansion chamber, remove coolant chamber attaching bolts
and lift off the crt. Pour out the old fluid, cleaned out with Windex, soap
and water, refilled to same level. Put it all back together and it only
required minor adjustment to get everything aligned.

Onto the green and red CRTs next...
