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 - 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
(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.
