0. General 3.Monitor the following auxiliary voltages.
When carry-out the electrical settings in many cases a video signal SOURCE ACROSS 7114 Pin and GRN +5 V +/- 0.25 VDC
must be applied to the monitor. A computer with : SOURCE ACROSS C2155 -6.1 V +/- 0.3 VDC.
SOURCE ACROSS C2141 +8.0 V +/- 0.4 VDC.
- ATI GPT-1600 (4822 397 10065), Mach 64 (up to 107kHz) SOURCE ACROSS C2153 +13.1V +/- 1.0 VDC.
SOURCE ACROSS C2154 - 13.1V +/- 1.0 VDC.
are used as the video signal source. The signal patterns are selected SOURCE ACROSS C2151 +83.0V +/- 1.0 VDC.
from the "service test software" package, see user guide 4822 727 SOURCE ACROSS C2609 - 170 V +/- 15.0 VDC.
21046 (GPT-1600). SOURCE ACROSS C2152(+ to Gnd) +180.0V +/-2.0 VDC.
4. General conditions for alignment
0.1 This monitor has 8 factory-preset modes as below.
720 x 400 31.5 kHz/70 Hz 1024 x 768 68.7 kHz/85 Hz 4.1 During all alignments, supply a distortion free AC mains voltage
640 x 480 31.5 kHz/60 Hz to set via an isolating transformer with low internal impedance.
640 x 480 43.0 kHz/85 Hz 4.2 Align in pre-warmed condition, at least 30 minutes warm-up with
800 x 600 46.9 kHz/75 Hz nominal picture brightness.
800 x 600 53.6 kHz/85 Hz 4.3 Purity, geometry and subsequent alignments should be carried
1024x768 60.0 kHz/75 Hz out in magnetic cage with correct magnetic field.
1280 x 1024 64.0kHz/60Hz
