I think the flyback is going out.. it shows signs of burning. Not
much so i was hoping a little epoxy might fix it. Right now the set
is playing audio but no CRTs are lit. Two red indicators on the power
supply board are lit. Other than that I need a schematic or repair
manual to check the voltages and what they should be. I openly admit
Im not great with projection TV's. But this is a personal project so
please dont tell me to take it to a shop that specializes in
Projection TV's. I came here for help, so can someone look it up in
your handy dandy book and give me a pointer in the right direction. I
am more than willing to do the work i just need a little technical
info. Any one that might be willing?

Please email me if you'd like to send a diagram.. or reply here and
I'd be very thankful for the help.

If you can see the damage, consider it gone.

IIRC, these sets usually short out the HV output
transistor and blow the 0.33 ohm emitter resistor
when the flyback goes.

But more often it's not the flyback, but the blue CRT; take a small flashlight
and look into the blue tube (on the right looking at set from the back) and see
if you can see any cracks in the face of the tube, under the probably cloudy
fluid. Also check and see if there's any fluid in the neck area of the tube.
