L6B2 for a Blue screen
3. You can probably get a 10 microhenry choke at Radio Shack, or it is available
for $1.28 (plus a $5 Handling charge) from Digikey Corporation at (800) 344-
4539. They take Mastercard, Visa, and C.O.D.. The Digikey part number is M8025-
ND.
4. After replacing this part, the monitor colors may need to be readjusted via
the small color trimpots on the same circuit board.

010- How do I adjust Centering on my GS RGB color
monitor?
Color monitors do vertical and horzontal centering differently than do
monochrome monitors. Almost all color monitors have either a jumper arrangement
or actual centering controls, sometimes both. Centering adjustments are usually
located on the PCB with no access holes, so the back will most likely have to be
removed to get to them.
If your monitor uses jumpers, there should be 3 tabs that each jumper can
be connected to. For vertical adjustment the tabs should be marked as 'up',
'down', and center. If your pix is too high, then you would connect the jumper
to the down tab. For horizontal adjustment the three tabs should be marked
'left', 'center', and 'right'.
If your monitor has centering controls, then adjust for best centering.
Many GS monitors use small tab switches to adjust centering. These are
located near the back of the main circuit board.
Adjustment of Vertical Size, etc. via shafts on back of GS monitor can
affect centering. For small changes, these adjustments may get the job done.
Adjustment of Intensity and Focus (see below) can affect centering.
