I found one of these projection sets, I liked it because of the bose hi-fi,
and dolby sorround.

Anyway, The set had a very dim picture, it was out of focus, and there was
no green period.

The back of it was missing, and I found the model number on a sticker.

I fixed the out of focus problems, and I turned the picture off from 0 to
give a great picture. It has a great purple picture, but no green. there is
absolutely no raster at all on the green tube. The filiments are lighting in
all 3 tubes, and HV is there.

I pulled out the CRT neck board, and with other zenith sets I worked on,
alot of the color problems are open resistors on the CRT neck board.

I checked every component on the neck board. All of the transistors are
good, and no shorted/open diodes, and every resistor tests within tolerance.
Im thinking its in the video output board.

Any ideas? is this a common problem, anyone know? I tried cranking the G2
all the way up, it makes no difference. Still no green raster.

try moving either the red or blue CRT board over to the green CRT and see if it
still won't light; that'll tell you if it's tube or circuits...
