Model:          KW-34HD1                                                            No.       481
Subject: Uneven Brightness From Left Side To Right                                  Date: May 2, 2000
         Side, Noticeable Bar Near Center Of Screen


Symptom:
 (1320)                The brightness may not be uniform across the screen. The area where the different
                       brightness levels meet may appear as a faint vertical bar just right of the center of the
                       screen.



Solution:              Dress all audio/video cables as straight back as possible from the rear of the set
                       where they connect to the input jacks. Avoid dressing the cables along the rear edge
                       of the cabinet between the input jacks and the left side of the cabinet (as viewed from
                       the front).

                       Also, replace the U-board with a new one specifically designed to help reduce the
                       severity of the symptom. The U-board is the small board that contains most of the
                       input jacks; it connects to the A-board.
