CAUTION: THIS SERVICE MANUAL IS ONLY FOR PROFESSIONAL SERVICE PERSONNEL'S
REFERENCE. BEFORE SERVICING THIS CHASSIS, PLEASE READ THE
FOLLOWING NOTICE ITEMS.
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
under 30 kV at zero beam current (minimum brightness) under DC135V main power(B+) , the high voltage
must not, under any circumstances, exceed 32 kV.
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.
* When checking, main power (B+) should be kept at (135 V : for 24", 100V : for 20").
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
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.
1.4 General instruction
1.4.1 This chassis' EEPROM N801 M24C08 should copy standard data first, if necessary, deal it with
"factory adjustment". If directly use blank EEPROM, should first preset I2C data, then go on other
common alignment. For factory adjustment method, refer to The appendix: Factory adjustment
mode.
1.4.2 If without special indication, the alignment is conducted on the below condition:
a AC power supply 120 V/60 Hz. North America area or others (depending on selling market).
b The whole unit is preheated for more than 30 min.
1.4.3 There is built-in auto degaussing circuit, it will degauss automatically within 1second after turning on.
And the auto degaussing circuit can effect only when turning off the set and waiting for at least 30min
and then turning on.
1.4.4 If CRT is with magnetism and affects color purity and convergence, the internal degaussing can not
degauss completely, can use degaussor to degauss externally. If color purity and convergence is still poor,
then do color purity and convergence adjustment.
