<Optical axis adjustment>
This adjustment is needed if black fringe appears on the screen.
To do this, readjust the fly-eye lens (for the incident light). First detach the top panel.
1. Disconnect the LCD flat cable from the main PWB connector.
2. Remove the lock screws from the main PWB, and slide the main PWB out of position.
3. Turn on the power and make sure the lamp lights up.
4. Using a hex wrench, loosen the fly-eye adjustment plate lock screws.
5. Using the specific eccentric cam adjustment wrench, turn the eccentric cams. The eccentric cam (2) is for
adjusting the x axis (horizontal). The eccentric cams (1) and (3) are for adjusting the y axis (vertical) and the
θz axis, respectively.
6. Finally, tighten up the lock screws.
Note 1: The eccentric cams are used for this adjustment. This means that their turning and the optical axis
movement do not linearly correspond to each other.
