Electrical Instructions

0. General:

When carrying out the electrical setting, in many cases a video
signal must be applied to the monitor. A computer with :

- "ATI VGA1024" interface card

- PGA1024 (4822 212 30916)

- PGA1280 (4822 212 30917)

are used as the video signal source. The signal pattern are selected
from the "service test software" package. see user guide 4822 727
19896 (ATI 1024), or 4822 727 20273 (PGA 1280).

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, 31.5kHz/60Hz (only) as signal source.

0.3 AC/DC measurement:

2. EHT voltage (3540)

- Connect a dc voltmeter between capacitor 2643 joint and ground.

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

- Select the "crosshatch" pattern. Adjust trimming pot-meter 3540
until the DC voltmeter reads : 67.5 +/- 0.2V (for PHILIPS CRT),

But 68 V for CPT CRT

3. Monitor the following auxiliary voltages

+12V source across C2158 +12.7V +/- 0.5 VDC

- 12V source across C2162 - 12.7V +/- 0.5 VDC
+8V source across C2172 +8.0V +/- 0.4 VDC
+6V source across C2164 +6.2V +/- 0.3 VDC

-178V source across C2647 -178V +/- 8.0 VDC

+180V source across C2153 +183V +/- 1.5 VDC

+5V source across C2168 +5.0V +/- 0.25VDC

+80V source across C2156 +81.0 V +/- 0.5 VDC

4. General conditions for alignment

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.

Note: Do not use heatsink as ground.

4.5 Adjust brightness controls to center position except for contrast
control which should be set to MAX.

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.

1. B+ Supply voltage (3178), 81 VDC

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

- Set the trimming pot-meters 3178/3540 in the mechanical mid­position (this is a pre-setting).

- Connect a DC voltmeter between capacitor 2156 joint and ground.

- Switch on the monitor.

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

- Select the "crosshatch" pattern.

- Adjust trimming pot-meter 3178 until the DC voltmeter reads 81 V
+/- 0.2V.

5. To access Factory Mode:

1. When "shift" LED is off, control is at 1st level, and when LED is on,
control is at 2nd level.

2. "Shift" LED will flash 0.1 second at the time when function keys (e.g.
H-Shift, H-Size,...,etc.) are pressed, and it should flash continuously
when adjusting "+" or "-" is at end of range. Releasing "+" or "-" key,
all adjusted values will be stored automatically after 10 seconds.(at
user Mode).

3. Factory preset mode entry, in power on status pressed "H-shift" and
"V-size"simultaneously at 1st level. After 2 seconds the shift led will
flash 3 times then the u-controller will entry factory mode.

( turn off power and then on to return to user mode)

4. "Power down overrule" is only functional in power saving status and
will be reset by switching off power.

5. At factory adjust mode, Press Shift key( shift LED on) then press V­size, the modified data will be stored in factory preset area on
EEPROM and shift LED will flash two times.

6. At service, please entry Factory mode (pressing H-Shift and V-size
simultaneously) first before using service factory alignment tools or
auto-alignment to perform factory alignment.

10. Purity adjustment

- Make sure the monitor is not exposed to any
external magnetic field.

- Produce a full red pattern on the screen, adjust the
purity magnet rings on the PCM assy (on CRT) to
obtain a complete field of the color red. This is done
by moving the two tabs (2-pole) in such a manner
that they advance in an opposite direction but at
the same time to obtain the same angle between
the two tabs, which should be approximately 180
degree.

- Check by full green pattern and full blue pattern
again to observe their respective color purity.

11. Static convergence

Electrical Instructions(continued)

2-pole purity magnet
6-pole convergence magnet
4-pole convergence magnet
Deflection Yoke

Introduction
Slight deviation in the static convergence can be
corrected by using two permanent pairs of magnets
which are fitted around the neck of the CRT. These
are the 4-pole magnet and the 6-pole magnet.
The 4-pole magnet move the outermost electron
beams (R and B) parallel in the opposite direction
from the other. The 6-pole magnet moves the
outermost electron beam (R, B and G) parallel in the
opposite direction from the other.
The magnetic field of the above magnets do not affect
the center of the CRT neck.

Setting

- Before the static convergence setting can be made,

the monitor must be switched on for 30 minutes.

- The focus setting must be made correctly.

- Signal: 640 * 480, 31.5 kHz/60 Hz mode.

- Set the tabs of the 4-pole magnet in the neutral

position. This is when the tabs are opposite one
another. In this position the magnets do not affect the
deflection of the R and B electron beams.

- Set the tabs of the 6-pole magnet in the neutral

position. This is when the tabs are opposite one
another. In this position the magnets do not affect the
deflection of the R, B, and G electron beams.

- First set the 4-pole magnet optimally.

- Then set the 6-pole magnet optimally.

- If the convergence is not now optimal, then adjust to

the optimal setting with the 4-pole magnet and then with
the 6- Pole magnet again.

- Set the tabs of the 6-pole magnet in the neutral

position. This is when the tabs are opposite one
another. In this position the magnets do not affect the
deflection of the R, B, and G electron beams.

- First set the 4-pole magnet optimally.

- Then set the 6-pole magnet optimally.

- If the convergence is not now optimal, then adjust to

the optimal setting with the 4-pole magnet and then
with the 6- pole magnet again.
