Page 6: Safety Precaution
Safety Precautions IMPORTANT SAFETY NOTICE The parts identified by many electrical and mechanical parts in this chassis have special safety-related characteristics in the Schematic Diagram and Replacement Parts List. It is essential that these special safety parts be replaced with the same components as recommended in this manual to prevent X-RADIATION, Shock, Fire, or other Hazards. -
Page 7: Warning And Caution
Warning and Caution 1. When you clean the TV set, please pull 4. To prevent the TV set from firing and electric out the power plug from AC outlet. Don’t shock, don’t leave the clean the cabinet and the screen with TV set in the rain or benzene, petrol and other chemicals. - Page 8 Generally, it is not needed to clean the tube surface. However, if necessary, its surface can be cleaned with a dry cotton cloth after cutting off the power. Don’t use any cleanser. If using hard clothe, the tube surface will be damaged. CAUTION: Before servicing receivers covered by this service manual and its supplements and addenda, read and follow the SAFETY PRECAUTIONS.
- Page 9 damage caused by static electricity 1) Immediately before handling any semiconductor component or semiconductor- equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available charging wrist strap device, which should be removed to prevent potential shock, prior to applying power to the unit under test.
- Page 10 c. Quickly move the soldering iron tip to the junction of the component lead and the printed circuit foil, and hold it there only until the solder flows onto and around both components. ie. lead and the foil. CAUTION: Work quickly to avoid overheating the circuit board printed foil. d.
- Page 11 Fuse and Conventional Resistor Removal/Replacement 1) Clip each fuse or resistor lead at top of the circuit board hollow stake. 2) Securely crimp the leads of replacement component around notch at stake top. 3) Solder the connections CAUTION: Maintain original spacing between the replaced component and adjacent components and the circuit board to prevent excessive component temperatures.
