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
