SAFETY PRECAUTIONS 4. SAFETY PRECAUTIONS INPORTANT SAFETY NOTICE These parts are identified by many electrical and mechanical parts in this chassis have special safety-related characteristics. It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent X-RADIATION, Shock, Fire, or other Hazards.
Warning and Cautions 5.Warning and Cautions 1. When you clean the TV set, please pull 4. To prevent the TV set from firing and out the power plug from AC outlet. Don't electric shock, don't clean the cabinet and the screen with make the TV set rain benzene, petrol and other chemicals.

Warning and Cautions Explanation on the display tube 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 cloth, the tube surface will be damaged.
Page 8
Warning and Cautions by this service manual might be equipped. 7. Do not apply AC power to this instrument and/or any of its electrical assemblies unless all solid-state device heat sinks are correctly installed. 8. Always connect the test receiver ground lead to the receiver chassis ground before connecting the test receiver positive lead.
Page 9
Warning and Cautions Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise even some normally harmless motions such as mutual brushing of your clothes’ fabric or lifting of your foot from a carpeted floor might generate static electricity sufficient to damage an ES device.) General Soldering Guidelines 1.
Page 10
Warning and Cautions Draw away the melted solder with an anti-static suction-type solder removal device (or with solder braid) before removing the IC. Replacement Carefully insert the replacement IC in the circuit board. Carefully bend each IC lead against the circuit foil pad and solder it. Clean the soldered areas with a small wire-bristle brush.(It is not necessary to reapply acrylic coating to the areas).
Page 11
Warning and Cautions 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.
