General points
1.
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 - 132 VAC for USA 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 measured or applied with respect to ground,
unless otherwise stated.
Note: don't use heat-sink as ground.
1.4 The test has to be done on a complete set including LCD panel
after 30 minutes warm-up at least 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.
Input signal
2.
2.1 Signal type
2.1.1 Video signal input
Signal source: pattern generator format as attachment.
(Table 1 to 34) Reference generator: QuantumData 802BT
The input signals can be applied in two different modes:
1). VESA Analog
The video input consists of red, green, and blue signals. The
video signals are analog levels, where 0V corresponds to
black and 700mV is the
impedance of video pins is 75 ohm +- 1%.
2.1.2 Sync signal input
The capability of sync signal inputs shall include separate sync,
composite sync and sync on green. input impedance: 2k2 ohms
The signals are defined as follow:
Separate sync
Composite sync
Sync on green H-sync
Signal source : pattern generator format as attachment (Table 1
to 34) Reference generator: QuantumData 802BT
