REFERENCE. BEFORE SERVICING THIS CHASSIS, PLEASE READ THE
FOLLOWING NOTICE ITEMS.

1.3 PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the chassis have special safety-related characteristics. These
characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIATION protection
afforded by them cannot necessarily be obtained by using replacement components rated for higher
wattage, etc. Replacement parts which have these special safety characteristics are identified in this
manual and its supplement electrical components having such features are shaded on the schematic
diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The use of
substitute replacement parts which do not have the same characteristics as specified in the parts list
may create shock, fire, X-RAY RADIATION or other hazards.

4 Debugging instruction
4.1 enter into the factory debugging menu
use to the remote control(RC-A23),follow to the blow model enter into the factory:
DISPLAY → MUTE → MUTE → MUTE → enter into the factory
press “sleep” button for pages upward, press “return” button for pages downward, press “CH+/-” to
select alignment items and “VOL+/-” to adjust volume, press “MUTE” to exit.
If the remote sensor designed for alignment is unavailable, press the following buttons to enter by
using user remote sensor
4.2 B+ voltage adjustment
Check B+ voltage ( negative pole of VD509) by using DC voltmeter DC 200V
14”110 V±1 V CRT 21”PF 100 V CRT A15QDX992X002(H)
21”110 V±1 V CRT 54SX503Y22-CD01 A51LVV898X12
4.3 AGC adjustment
Measure the voltage of RF AGC by connecting digital DC voltmeter with TP1, receive weak signal
(40dBu) and the static AGC voltage of TP1 AGC should be V1=4V±0.2V; the receive medium signal
(60dBu), adjust the value of PAGE8 RF. AGC of factory menu and the start-control voltage of TP1 AGC
should be V2=3.5V±0.2.if V2>3.5V, then the voltage is -1 or -2,if V2<3.5V, then the voltage is+1 or+2.
after adjustment the picture should not appear no-sync , distortion and moire.
White balance and screen-grid voltage VG2 adjustment
After enter PAGE3 of factory menu, use remote sensor directly to adjust white balance by pressing the
following digital buttons:
“1”=R.BIAS(+) “2”=G.BIAS(+) “3”=B.BIAS(+)
“4”=R.BIAS(-) “5”=G.BIAS(-) “6”=B.BIAS(-)
press “pp” button to select picture mode→T1→T2→bright→soft→nature→user→ the current picture
mode will be display on the screen.
The T1 mode has the maximum value of brightness and contrast with all the other items min. Value of all
the analog are minimum while in T2 mode.
Before adjustment you should set the following items :SUB-BRIGHT=50, R.B=100, G.B=100,
B.B=100, R.D=100, G.D=15, B.D=100
Adjustment method: 1. press PP button to select T2 picture mode, press CH+/- to select V.K, press vol+
to let the field scanning fail to oscillate, adjust the screen-grid potentiometer on FBT clockwise to let
horizontal bright line just appear on the screen; let the value of G.B unchanged, adjust R-BIAS and
B-BIAS to let the horizontal bright line appear white. If the green horizontal line don’t appear firstly,
fine-turn the screen-grid voltage, the adjust R.B and B.B until red , green and blue just appear. After
adjustment press VOL- to obtain normal field scanning mode.
4.4 Receive grey-scale signal (D8), enter PAGE4 of factory menu, press PP to select T2 picture mode,
3
adjustment SUB-BRIGHT to let picture on the screen microbright.
4.5 receive white balance adjustment signal
enter PAGE3 of factory menu, press PP to select T1 picture mode, let the value of GD unchange, adjust
RD and B.D to let the white part of the picture appear “white”.
4.6 Use white balancer to rectify the white balance under following conditions
colour temperature:12000K+8MPCD
x =0.270± 0.008 Y=0.283±0.008 dark space : 4.5nit, bright space: 60nit
Note:1. Check the white balance of bright field and dark field by receiving monochrome signal or
adjusting the degree of saturation to minimum under maintenance condition, adjust RGB BIAS in dark
field and RGB DRIVE in bright area, adjust bright/dark balance repeatedly until the bright and dark
field have no colour drift.
2. While the colour saturation changed from maximum to minimum, if the dark balance appears
changeable, adjust RY.DC.LVL and BY.DC.LVL (page3) to let it coincide with white balance.
3. If the dark balance appears changeable while connected with DVD, adjust YUV.BY.DC and
YUV.RY.DC (PAGE4) to let it conincide with white balance.
4.7 High voltage and filament voltage check
Connect a high-voltage meter between anode cap of picture tube and the ground, measure the filament
voltage using rms voltmeter, set the picture mode to “standard”, the high-voltage: 24.5KV±1KV of 21”,
22.5KV±1KV of 14”,filament voltage: 6.3±0.1Vrms.
4.8 x -ray protection check
Receive local TV signal, set the picture mode to “standard”, shorten the circuit and measure the
value of TP1-TP2, restart the TV 30 seconds after turn off the power source and it should return to
normal.
4.9 AV function check
according to the owner’s manual require, connect to the AV equipment and the AV interface:
VIDEO IN: 1 Vp-p 75OHM AUDIO IN: (-8±3)dBm>47 kOHM
S interface Y IN: 1 Vp-p 75OHM C IN: 0.3 Vp-p 75OHM
