Convergence And Focus Adjustments Mechanism - Sharp XG-C40XU/XE Service Manual

4. With the G-LCD panel's screen center as refernce, adjust the R-LCD and B-LCD panels.
5. Finally tighten up the convergence lock screw "d".
Notes :
1 The eccentric cam is used for convergence adjustment.
This means that the cam's turning and the linear movement are not always uniform.
2 This model is not equipped with the LCD image adjustment mechanism. This is because the cross-dichroic
prism is used for image formation. When the LCD panels all get into best focus, the images are almost
completely converged.
