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 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
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.
