1. SAFETY INSTRUCTION AND GENERAL INSTRUCTION
Before servicing and aligning this equipment, please read the following “X-RAY RADIATION
PRECAUTION” , “SAFETY PRECAUTION” and “PRODUCT SAFETY NOTICE”.
1.1 X-RAY RADIATION PRECAUTION
1）Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such
hazards, the high voltage must not be above the specified limit. The normal value of the high voltage
of this receiver is below 31.5kV at 1.6A beam current, the high voltage must not, under any
circumstances, exceed 33kV.
2）Each time a receiver requires servicing, the high voltage should be checked following the HIGH
VOLTAGE CHECK procedure in this manual. It is recommended the reading of the high voltage be
recorded as a part of service record. It is important to use an accurate and reliable high voltage
meter.
3）The primary source of X-RAY RADIATION in this TV receiver is the picture tube. For continuous
X-RAY RADIATION protection, the replacement tube must be exactly the same type tube as
specified in the parts list.
4）Some parts in this receiver have special safety-related characteristics for X-RAY RADIATION
protection. For continuous safety, parts replacement should be undertaken only after referring to the
PRODUCT SAFETY NOTICE below.
1.2 SAFETY PRECAUTION WARNING:
Service should not be attempted by anyone unfamiliar with the necessary precaution on this receiver.
The following are the necessary precautions to be observed before servicing this chassis.
1) Since the power supply circuit of this receiver is directly connected to the AC power line, an isolation
transformer should be used during any dynamic service to avoid possible shock hazard.
2) Always discharge the picture tube anode to the CRT conductive coating before handling the picture
tube. The picture tube is highly evacuated and if broken, glass fragments will be violently expelled.
Use shatter proof goggles and keep picture tube away from the unprotected body while handling.
3) When replacing a chassis in the cabinet, always be certain that all the protective devices are put
back in place, such as: non-metallic control knobs, insulating covers, shields, isolation
resistor-capacitor network etc.
4) When replacing parts or circuit boards, disconnect the power cord.
5) When replacing a high wattage resistor (oxiode metal film resistor) on the circuit board, keep the
resistor 10mm (1/2in) away from circuit board.
6) Connection wires must be kept away from components with high voltage or high temperature.
7) If any fuse in this TV receiver is blown, replace it with the FUSE specified in the chassis parts list.
1.3 PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the chassis have special safety-related characteristics. These
Note:This service manual is only for professional service personnel’s reference. Before
servicing the unit, please read the following items carefully.

2
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 of 135V±2.
4.3 AGC adjustment
Measure the voltage of RF AGC by connecting digital DC voltmeter with TP3, receive weak signal
(40dBu) and the static AGC voltage of TP1 AGC should be V1=4V±0.2V; the receive antenna signal
(60dBu), adjust the value of P6 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. the
antenna input 100dBu signal, after the picture should not be appeared no-sync , distortion and moire;
input 35-40dBu weak signal ,it should not be appeared distortion and no-sync and sound abnormity
electrophoresis of it.
4.4 White balance and screen-grid voltage adjustment
After enter P5 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 “p-p” button to select picture mode custom→T1→T2→bright→soft→nature→user→custom will
be display on the screen.
The T1 mode has the maximum value of brightness and contrast with all the other items minum. 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
press “P-P” button to select T2 picture mode, press CH+/- to select LINE, press vol+ to let the field
scanning fail to oscillate, adjust the screen-grid potentiometer on FBT clockwise to let horizontal bright
