I am missing the blue on my monitor and I'm trying to pinpoint the problem.
I tested the tube colors by shorting each gun and all 3 colors are there.
I checked the C3782 on the blue and I get continuity on the 2 outer pins so I testing the c3782 on the red and green there is no continuity.
Does this mean that the blue transister is bad? Or am I doing this all wrong?

Also is this a part I can get at my local Radio Shack?
 
Those transistors are the same from color to color on that neck board so move the suspected bad one to another position and see if the problem stays with the color or moves. If it stays then something else is wrong if it moves then you got it.

When you shorted the guns did you do it at the pin on the neck board or the tabs on the transistors? Could be cold solder or a broken tace from the transistor to the socket.

I shorted them on the neckboard pins..I switched the transistors red and blue around and now the red is gone and the blue is back so the transistor it is.

Thanks! Why didnt I think of that. :)
 
I received my transistor today and installed it and all is well.
When I got this from the previous owner he said the monitor was missing the blue and he thought it was a bad tube so I got really cheap for a deluxe cab $100.00. And now the blue is back for just $5.00 for the part Im pretty stoked! :)

I still need to adjust the colors but here are before and after pics.
