SAFETY PRECAUTION
Warning: Refer Servicing to Qualified Service Personnel Only
1. The TV has a nominal working EHT voltage of 25kV. Extreme caution should be exercised
when working on the TV with the back removed.
a. Do not attempt to service this TV if you are not conversant with the~ precautions and
procedures for working on high voltage equipment.
b. When handling or working on the CRT, always discharge the anode to the TV
chassis before removing the anode cap in ease of electric shock.
c. The CRT, if broken, will violently expel glass fragments. Use shatterproof goggles
and take extreme care while handling.
d. Do not hold the CRT by the neck as this is a very dangerous practice.
2. It is essential that to maintain the safety of the customer all power cord forms be replaced
exactly as supplied from factory.
3. Voltage exists between the hot and cold ground when the TV is in operation. Install a suitable
isolating transformer of beyond rated overall power when servicing or connecting any test
equipment for the sake of safety.
4. When replacing ICs, use specific tools or a static-proof electric iron with small power (below
35W)
5. Do not use a magnetized screwdriver when tightening or loosing the deflection yoke assembly
to avoid electronic gun magnetized and attenuation in convergence of the CRT.
6. When remounting the TV chassis, ensure that all guard devices, such as nonmetal control
buttons, switch, insulating sleeve, shielding cover, isolating resistors and capacitors, are
installed on the original place.
7. Replace blown £uses within the TV with the fuse specified in the parts list.
8. When replacing wires or components to terminals or tags, wind the leads around the terminal
before soldering. When replacing safety components identified by the international hazard
symbols on the circuit diagram and parts list, it must be the company-approved type and must
be mounted as the original.
9. Keep wires away from high temperature components.
