I did a total rebuild kit on the monitor. No spot killer on. Neck glow and yoke chatter. Does not seem like I am getting any HV. Rechecked all work done transistors, reflowed all header pins etc. Still not getting any reading on P900 pins. I have tried just about everything I have read so far on earlier posts but can't seem to fix it. Also no white dot with brightness all the way up. Any help would be great.
 
Are you getting no voltage at all on any of the P900 pins? You should have +28V and -28V on some of the pins, if the cage is getting power.

If so, and you aren't getting 180V on pin 5 of P900, something's wrong with your HV cage. Could be many things. Test all transistors and diodes. Look for damage to the HV transformer (e.g., if it's melted on the side.) Make sure HV adjustment pot isn't cracked or broken. Hard to say exactly without more info, but it's most likely something in that box.

If not, check that you are getting +/-28V at the LV2000, and trace it to the HV cage pins.
 
I have found many HV cages to have broken traces under the pins on the sides. Make sure that you have good continuity from each pin to the next part in the circuit. If not,. you may have to solder in a jumper.
