Convergence And Focus Adjustments Mechanism - Sharp XV-Z1A Service Manual

XV-Z1E/A
Note :
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 dichroic prism
is used for image formation. When the LCD panels all get into the best focus, the images are almost
completely converged.
