Are you saying the Blue driven at too a high a voltage? I would have
thought it was too low, or the others too high, causing the imbalance.
I have measured these with the CRT connected to the board and
disconnected with same findings.

Been working on this 29" TV and cannot work out why the voltage on the
one of the driver transistors is low. Drive transistors located on the
CRT neck board.

Blue =120VDC
Green =195VDC
Red =195VDC

Green does show up on the screen but very dull. Red/magenta hue. Am i
correct to say that the blue it under driven causing the complementary
color to produce the hue. Or are the other two guns over driven????

Since there is green am i to assume there is nothing wrong with the RGB
IC and it is still just a driver circuit problem

Where to diagnose from next??? Just stuck on this cos never come across
it before.

Thanks

You need to provide the rest of the troubleshooting voltage and
waveform measurements at the crt for anyone to help.

From the spartan information available, the blue bias or drive is way
too high.
