WG K6100 color vector only showing top half of the screen

I know that one or two of the bottle cap transistors are to blame for this issue, but can anyone tell me which ones so I don't replace the good ones?

Thanks!

Use a multi-meter set to the transistor setting and check the readings between the to pins. Should be between 500-1200 readings and make sure to pull the red molex connectors off the deflection board. Doing that will take them out of circuit. If you get no reading it's open and bad.

Oh, make sure you try both leads on each pin being it's going to read 0 testing it one way and not the other unless it's bad. In that case it'll read 0 both ways.
 
Also - check that the wires to those transistor sockets haven't broken off...
