1 safety instruction
1.1 X-RAY radiation precaution
1.1.1 Excessive voltage will cause harmful X-ray. To avoid this radiation hazard, the high voltage should
fall within the limitation. The appliance works at AC 220V, 60Hz. The high voltage of zero beam current
(brightness, contrast and color is min) should be within 27kV on condition that the main power (B+)
voltage isAC220V. And it should not exceed 28kV in any condition.
When servicing, please refer to the HIGH VOLTAGE CHECK procedure this service manual before
check the high voltage and the high voltage meter should be reliable and accurate.
* Keep the main power voltage at 220V when checking the high voltage.
1.1.2 The primary source of X-RAY RADIATION is the CRT. The CRT of this TV set have gotten the
approval of safety authentication inspection. The replacement CRT should be exactly the same type and
specification CRT which has gotten a similar safety approval, and check the high voltage according to
the HIGH VOLTAGE CHECK procedure.
1.2 safety precaution
a. Since the power supply circuit of this receiver is directly connected to the AC power line, an isolation
transformer is necessary during dynamic service to avoid possible shock hazard.
b.Always discharge the graphite layer conductor when moving the CRT.
c. Disconnect the power cord before replacing parts.
d. When replacing high-power resistor, keep the resistor 10 mm away from the circuit board.
1.3 Component safety precaution
Many electrical and mechanical parts in the chassis have special safety-related characteristics. These
characteristics are often passed unnoticed by a visual inspection. Replacement parts which have these
special safety characteristics are identified in this manual and its supplement electrical components
having such features are shaded or marked by 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 characteristic as specified in the parts list may create
shock, fire, X-RAY RADIATION or other hazards.
2.General instruction
2.1 Copy the standard model data to let EEPROM (N702 24C08)of the chassis have those data before
placing it on the unit, do “factory adjustment” if necessary. If use a blank EEPROM directly, you should
preset IIC data and then do other common adjustment. Refer to TABLE1 to preset EEPROM.
2.2 the adjustment should be done under following circumstances without additional instruction
a) Alternating current 220V/60Hz
b) Preheat at least 30 min
2.3The unit has auto degaussing circuit, the auto degaussing process can be finished within 2s when the
main power. Only when turn on the unit at least 20min after last time turn off TV does the auto
degaussing circuit work.
2.4 If the CRT with magnetism affects color purity and convergence, when the auto degaussing eraser. if
the color purity and convergence are still not very good, then corresponding adjustment should be done.
Refer to picture tube adjustment method for adjustment.
Note: This service manual is only for professional service personnel’s reference. Before
servicing the unit, please read the following items carefully.
