Here is a short video tutorial I did for Bender on how to adjust the B+ voltage on my Sanyo20EZ monitor in my Donkey Kong machine.
B+ Adjustment tutorial: This method can be used for all monitors. Reference your monitor's manual to determine the correct B+ voltage test point and what the expected B+ voltage should read.

what does adjusting the b+ voltage do? as in the appearance on the screen
Lutus:
Maladjusted B+ can do many things to screen geometry. In my case. I could not tune in the FOCUS and my HORIZTONAL deflection was such that I could only fill about 45% of the screen with the video signal. But mine was +88V when it should have been +108V. Any lower and it might have stopped coming on.
B+ is often overlooked, but it should be checked anytime after performing cap kits, HOT and flyback replacements, etc...
