The monitor on my cherry master only has red and blue.  What do i need to fix or replace? Pictures are very helpful for me, I have very basic electronics skills I can use a solder iron pretty good.  is it possible to change it out with an old tv tube using the same chassis, or is some of the problem with the chassis?  The model number of the chassis is 19k7901  the number on the tube is G-A48ACBO2X with a date of 1993.  Turning the ajustment knobs on the neck board I can only change between red and blue no yellows or greens.  I don't have a digital cam so I can't post any pics.  I will appreciate any help I can get I don't want to have to bring it in somewhere and have to pay more than the monitor is worth to get repaired

check transistor on the neckboard one is probably broken
suposse to get 3 transistor there 1 for red the other for the blue.. and one is for the green.
look on the connector probably they write where the G signal go.. fallow him to the transistor     Q202 = green :) check in the manual page 13
