NOTE
When taking voltage measurements be sure
to use the "Zero-Volt Reference Test Point"
the chassis is not connected directly to the
board ground. It goes through a lK resistor!
PROBLEM
If you put a kit into a cabinet that uses one
of WG's 4600 series monitors and you have
problems getting a good lock onto negative
composite sync, perform the following
simple modification
CAUTION
Although the chassis is at earth potential
(unless you cut the ground strap) you will get
out of spec voltage readings. If you have a
jumper between the power supply and earth
ground, the chassis will be connected
through the loop to DC ground.
SOLUTION
Cut the jumper on the Horiz/Vert board that
shorts out C35 l. The jumper is located near
the horizontal hold pot.
