• Remove the Light engine air filter and fan pack to access the blue convergence adjustment screws. For
details, see
5.6.2 Light Engine Fan Pack (4 fans).
NOTE:
Cooling is
greatly affected by removing the filter and fan pack assembly.
You do not always have to turn the screws simultaneously; however, adjusting one at a time will cause the need
for an equal or equal and opposite turn on the other to prevent binding and achieve the adjustment desired.
It is a good idea to locate the shorter blade 2.5mm driver on adjusting screw #2 (especially on the red), and use
the longer blade 2.5mm driver for screw#1 and horizontal (screw #3).
