Hello, I jus picked up an old Sony Projection TV got it home green CRT dead, red and blue seem to work fine, not getting any filament glow on the green checked easy obvious stuff loose connections broken wires, Any help would be greatly appreciated, as I am a Mechanic not a TV repair guy, but hey you pretty much have to have a degree in Electrical engineering
to work on these new cars! Thanks

:Oh BTW forgot to mention I unplugged the working blue CRT plugged the board into the green with no change.

The other red wires go to a block. You swapped CRT boards now you need to swap the rest.
