Electrical Instructions

1.General point

==========

1.1During alignment and measurement supply a distortion free AC-mains voltage to the apparatus via an isolating transformer with a low internal resistance.

1.2All voltages have to be measured or applied with respect to ground, unless otherwise stated. Note: Not all heatsinks are grounded, avoid using heatsinks as ground.

1.3The term "Linear RGB" is meant the 0.7 Vpp video with separate SYNC ( TTL Level ). Reference factory preset mode timings (format of pattern generator CHROMA-2135) are shown in TABLE 1 to TABLE 8. Preload timing TABLE 9 to TABLE 22.

1.4Any external voltage source should have low internal impedance.

1.5The alignment has to be done in room temperature 25 5C.

2.Pre warm-up

==========

2.1Align in pre-warmed condition at least 30 minutes during Manufacturing.

3.Main chassis alignment

==================

3.1Power supply adjustment :

All supply voltages were fixed and adjustment is unnecessary. (Check the voltages on Chassis line)

3.2Apply a VGA 31.5KHz/480 lines cross-hatch signal.

3.2.1 Adjust BPLUS of factory setting to obtain the anode voltage 25.0KV+/-1KVat zero beam current.

3.3Monitor the following auxiliary voltages.

+5 source across 7153 Pin out and GND		+5V	0.15 VDC
+6	source across C2154	+6.2V	0.2 VDC
+12 source across C2155		+12.6V	0.4	VDC
-12	source across C2156	-12.5V	0.4	VDC
+82	source across C2153	+82.0V	1.5	VDC
+190 source across C2152 ( + to Gnd)		+190.5V	3.0	VDC
-96 source across C2630		-96V	6.0 VDC

4.General conditions for aging and alignment

================================

4.1Aging/burn-in:Use low mains AC supply (90Vac) for monitor first power on test.Pre-adjust the Focus till cross hatch pattern can be clearly visible then enter the agingmode.

(Press both Up and Down keys, and then switch-on the monitor with signal cable disconnected.)

4.2During all alignments, supply a distortion free AC mains voltage to the monitor set via an isolating transformer with low internal impedance.

4.3All measurements are carried out at nominal mains voltage, unless otherwise stated.

4.4Align in pre-warmed condition, at least 30 minutes warm-up with nominal light output.

4.5Purity, geometry and subsequent alignments should be carried out in a 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

4.6All voltages are to be measured or applied with respect to ground , unless otherwise stated.Attention : Not all heatsinks are GND, avoid using heatsinks as ground.

4.7The white balance and purity has to be adjusted in dully lighted room.

4.8All alignments have to be done in a room with a temperature Of 25 10 C.

4.Alignment of Vg2, cut-off point, white tracking

=====================================

5.1EEPROM data has to be pre-set according to software approval sheets, sheet-139,

sheet-140: (loaded beforehand with average values of mode pre-set data and mode pre-set selection bytes.) The following table is for reference only.Optimum values should be determined by Factory(ME) for every production batch.

In factory, alignments are done via I2C on the I/F cable DDC bus , but the set can also be manually aligned. Enter factory mode by pressing both Up and Down keys while power-on. Select factory.
