0. General

1. B+ supply voltage

2. High-voltage EHT

When carry-out the electrical settings in many cases a video signal

must be applied to the monitor. A computer with :

- 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

21046 (GPT-1600).

0.1 This monitor has 6 factory-preset modes as below.

720 x 400 31.5 kHz/70 Hz

640 x 480 31.47 kHz/60 Hz

640 x 480 43.3 kHz/85 Hz

800 x 600 46.9 kHz/75 Hz

800 x 600 53.67 kHz/85 Hz

1024x768 60.0 kHz/75 Hz

0.2 With normal VGA card:

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.

0.3 AC/DC Measurement:

The measurements for AC waveform and DC figure is based on 640 x

480 31.5 kHz/60 Hz resolution mode with test pattern "gray scale".

Power input: 110V AC

- Apply a video signal in the 640 x 480 with 31.5 kHz/60Hz mode.

- Select the "cross-hatch" pattern.

- Set the brightness control and the contrast control to the minimum

position.

- Pre-set trimming potentiometer R3178(B+) and R3540 (EHT)

in mid-position.

- Set Vg2 (screen) to fully Counter-clockwise (zero beamcurrent).

- Connect a dc voltmeter between the joint of capacitor C2156 and

ground (common ground).

- Set the B+ trimming potentiometer R3178(B+) so that the reading

on the dc voltmeter is 81V +/- 0.2 Vdc.

- Apply a video signal in the 640 x480 with 31.5 kHz/60Hz mode.

- Select the "cross-hatch" pattern.

- Set the brightness control and the contrast control to the minimum

position.

- Turn off the power.

- Connect a dc voltmeter between the joint of capacitor C2643 and

ground (common ground).

- Turn on the power.

- Set the EHT trimming potentiometer R3540 so that the reading on

the dc voltmeter is 67.0V+/-0.2V (for PHI and CPT CRT).

factory-preload modes as below

640 x 350 31.5 kHz/70 Hz 832 x 624 49.7 kHz/74.5 Hz

640 x 350 37.9 kHz/85 Hz 1024 x 768 56.5 kHz/70 Hz

640 x 480 37.5 kHz/75 Hz 1280 x 960 60 kHz/60 Hz

640 x 480 37.9 kHz/72.8 Hz 800 x 600 48.1 kHz/72Hz

800 x 600 37.9 kHz/60 Hz

640 x 480 5.06kHz/100Hz

720 x 400 37.9 kHz/85 Hz

1024 x 768 48.3kHz/60Hz

3.Monitor the following auxiliary voltages.

5. To access factory mode:

5.1. To leave factory mode

SOURCE ACROSS C2153 and GRN +183.0V +/- 1.5 VDC

4.5 Adjust brightness controls to center position except for contrast

control which should be set to MAX.

- Turn off monitor (don't turn off PC)

- Press "

" and "

" simultaneously on the front control panel

,then press "

",wait till the OSD menu with characters

" factory mode (below OSD menu)" come on the screen of monitor.

- If OSD menu disappears on the screen of monitor, press "

again (anytime), then the OSD menu comes on the screen again.

- using "

" : to select OSD menu.

- using "

" : to increase or decrease the setting.

- Using "

" to confirm the selection.

* After alignment of factory mode, turn off monitor (if you do not turn

off monitor, the OSD menu is always at the factory mode), then turn

on monitor again (at this moment, the OSD menu goes back to user

mode).

SOURCE ACROSS C2156

+81.0V +/- 0.5 VDC.

SOURCE ACROSS C2164

+6.2V +/- 0.3 VDC.

SOURCE ACROSS C2158

+12.7V +/- 0.5 VDC.

SOURCE ACROSS C2162

- 12.7V +/- 0.5 VDC.

4.1 During all alignments, supply a distortion free AC mains voltage

to set via an isolating transformer with low internal impedance.

4.2 Align in pre-warmed condition, at least 30 minutes warm-up with

nominal picture brightness.

4.3 Purity, geometry and subsequent alignments should be carried

out in magnetic cage with correct magnetic field.

Northern hemisphere : H=0, V=450 mG, Z=0

Southern hemisphere : H=0, V=-500 mG, Z=0

Equatorial Support

: H=0, V=0

mG, Z=0

4.4 All voltages are to be measured or applied with respect to ground.

4. General conditions for alignment

Note: Do not use heatsink as ground.
