2. Color Temperature Adjustment GTW P42M102 TV Service mode
2.1.1 Color Temperature setting in DVI Mode:
(1) Turn on PDP set and warm up for over 30 minutes.
(2) Turn on Color Analyzer CA-100 and reset CA-100.
(3) Switch PDP input to DVI mode, press the “Recall” key on remote control to have
PDP set in factory default status.
(4) Set up Video Pattern Generator (Chroma, Model= C2226). Timing set = 640 x
480 @ 60Hz; Video = Panel Link, this is the DVI output mode. Connecting PDP
DVI input to Chroma to receive DVI signal.
(5) Dark level and bright level center block definition:
A. Dark level center block definition:
Pattern set = Pattern name = 1-mosaic,
Color form = norm,
