18 APPENDIX-A: Main assembly list APPENDIX-B: Exploded view Note: This service manual is only for professional service personnel’s reference.
Before servicing the unit, please read the following items carefully.
Safety instruction 1.
X-RAY radiation precaution 1.
1 Excessive voltage will cause harmful X-ray .
To avoid this radiation hazar d, the high volt age should fall within the limitation.
The appliance works at AC 110V, 60Hz.
The high voltage of zero beam curr ent (brightness is min) should be within 29kV on condition that th e main power voltage is AC1 10V.
And it should not exceed 33kV 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 110V when checking the high voltage.
1.
2 The primary source of X-RA Y RADIATION is t he CR T.
The CR T of this TV set h ave gotten th e approval of safety authentication inspection.
The replacement CRT should be exactly the same type and specification CRT which has gotten a similar safety appro val, and check the high volt age according to the HIGH VOLTAGE CHECK procedure.
2.
Safety precaution a.
Since the power supply circuit of this receiver is directly c onnected 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 be...
