1. General points
1.1 During the test and measuring, supply a distortion free AC mains
voltage to the apparatus via an isolated transformer with low
internal resistance.
1.2 All measurements mentioned hereafter are carried out at a normal
mains voltage (90 - 142 VAC for NAFTA version, 195 -264 VAC for
EUROPEAN version, or 90 - 264 VAC for the model with full range
power supply, unless otherwise stated.)
1.3 All voltages are to be measurement or applied with respect to
ground,unless otherwise stated.
1.4 The test has to be done on a complete set including LCD panel in
a room with temperature of 25 +/- 5 degree C.
1.5 All values mentioned in these test instruction are only applicable of
a well aligned apparatus, with correct signal.
1.6 The letters symbols (B) and (S) placed behind the test instruction
denotes
(B): carried out 100% inspection at assembly line
(S): carried out test by sampling
1.7 The white balance (color temperature), has to be tested in subdued
lighted room.
1.8 Repetitive power on/off cycle are allowed except it should be
avoided within 6 sec.

2.2 PC Input signal mode
2.2.1 PRESET VIDEO RESOLUTION
The analogue color LCD monitor must be capable of
displaying standard resolutions within the vertical
frequency range of 50 - 75 Hz, and horizontal scan
range of 30 - 63 KHz .
Use the CHROMA-2250 or QuantumData 802R
generator as the standard signal timing source.
Mode 3, 7, 8, 12, 15, 16 are preset modes that
should pass QA inspection.
Mode 1, 2, 4, 5, 6, 9, 10, 11, 13, 14 will run auto
adjustment only, and W/O QA
checking.
