1.
Open the projector’s topcover and remove it.
Next, it requires to open the RGB module’s cover too, then you will see the laser diodes layout inside as
picture below.
2.
Create a full size white circle (static tunnel effect) and check whether the green and blue circle are totall out of the red circle.
If yes, we will see the colors split each other. Next step is to redo alignment for the Green and Blue beam to overlay on the red beam.
Slightly adjust the green and blue until the all three colors well overlay on each other to become the white color circle.
Detailed beam alignment steps:
2-1.
Adjust the Blue beam--as pictures shown
Use a proper allen key insert the slot places on side of the blue light mount
and then slightly pry the mount on vertical position, while you can use the allen to pry the both slots place
on top of the mount--repeat left or right side to adjust the beam’s position. So that to make the blue beam layout with the red beam,
keep this action until both light paths(blue & red) overlay each other's centre well.
2-2.
Adjust the Green beam should be same as the procedures that adjust the Blue beam
