0. General
With normal VGA card:
AC/DC Measurement:
When carry-out the electrical settings in many cases a video signal
must be applied to the monitor. A computer with :
- ATI VGA 1024 V6-1.04/PH BETA4 interface card
- PGA 1024 (4822 212 30916), Mach 8.
- PGA 1280 (4822 212 30917), Mach 32.
- ATI GPT-1600 (4822 397 10065), Mach 64 (up to 107kHz)
are used as the video signal source. The signal patterns are
selected from the "service test software" package, see user
guide 4822 727 19896 (ATI1024),
or 4822 727 20273 (PGA 1280), or
4822 727 21046 (GPT-1600).
0.1
If not using the ATI card during repair or alignment, The service
engineer also can use this service test software adapting with
normal standard VGA adaptor and using standard VGA mode
640 x 480, 31.5 kHz/60 Hz (only) as signal source.
0.2
The measurements for AC waveform and DC figure is based on
640 x 480 31.5 kHz/60 Hz resolution mode with test pattern
"16 gray scale".
Power input: 110V AC
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 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
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.
(1) Preset Modes (29 modes)
(2) Factory Preset Modes (15 modes)
2.2 Input signal mode

Signal type
2.1.1 Analog Video : 0.7 Vp-p linear, positive polarity
Sync. : TTL level, separate, positive or negative polarity
Signal source: pattern generator format as attachment.
