WN-5230-S VideoWall User’s Guide
For an image that is way out of alignment and that needs major adjustment, start with everything in a “normal” position:
•If the screen is
•Each corner of the optical engine mount should start at the same distance out. Factory default is 3 cm, but any distance near this amount will do a good job. Make a block of wood that is 3 cm thick and use it as a gauge at the four corners of the metal engine mount. Then adjust S1, 2, 3, and 4 to make the engine mount just touch the block.
•Adjust the lens screws, LS1 and LS2, so they are part way in. As these screws turn out, eventually they reach a point where the spring no longer pushes the lens toward the screw. Have the lens in a middle position, so that the spring is pressed some, but not as much as half way.
Adjusting the Image
There are four nuts on the engine mounting plate, S1, S2, S3, and S4. Adjust these in pairs and turn them equal amounts.
