Chapter 19 - Adjustments
White Balance / Brightness
The service manual shows a series of white balance and brightness level adjustments for the TV, Twin, Video
inputs and component inputs. They can be touched up when changing the BB and BC boards and must be
adjusted when replacing the M board.
Geometric Distortion
There are no adjustments for geometric distortion. That is adjusted in the preassembled optical unit. If there is
geometric distortion, inspect the mirror (top) area of the TV for damage.
Convergence
Convergence is not adjusted in this set. The LCD panels are positioned at the factory for convergence. Figure
19-1 shows a crosshatch pattern. If convergence is off, the top mirror assembly and the optical unit where the
LCD panels are located are both suspect. If the misconvergence is on one side of the screen accompanied by
geometric distortion, the mirror may have broken from their mounts. In this case, reinstall the mirror or replace
the entire upper assembly (mirror, screen, bezel and speakers as one assembly. P/N = A-1603-167-A.
