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 re...
