Subject: White Saturation, Loss Of Detail In Bright Date: September 19, 2000
Areas Of Scenes That Are Predominately Dark.
Symptom:
(D325) In bright areas of scenes that are predominately dark, the picture may be excessively
white and/or bright. This may result in a loss of picture detail in the bright areas.
Conditions under which the symptom may appear:
1- In the full screen mode, when playing a 480p source (like progressive-scan DVD).
2- In Twin-View mode, when playing a 480i source on the right-side window while TV,
VIDEO-1, VIDEO-2, VIDEO-3, or VIDEO-4 is selected for the left-side window.
Solution: If the customer complains of this symptom, replace the B-board. B-boards received
from WRPC-AS for service have already had the resistor changes shown below. In
the event that B-boards are out of stock in WRPC-AS, the set's original board can be
updated by making the resistor changes shown below.
