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 8. Always connect the test receiver ground lead to the receiver chassis ground before connecting the test receiver positive lead. Always remove the test receiver ground lead last. 9. Use with this receiver only the test fixtures specified in this service manual. CAUTION: Do not connect the test fixture ground strap to any heat sink in this receiver.

Warning and Cautions Excessive heat applied to the copper foil of any printed circuit board will weaken the adhesive that bonds foil to the circuit board causing the foil to separate from or “lift-off” the board. The following guidelines and procedures should be followed whenever this condition is encountered.

Circuit Explanation is operational with dual power supply, forward and backfly power supply, obtained through line output amplification and of +14V and -14V, respectively. 4. Muting circuit and shut-down silence circuit The muting circuit enables N901(CPU) to generate high level to raise the power level of pin 10 of N602 (for left and right audio channels control) and pin 9 (for bass sound control) to achieve the muting result (output at high level of pin 10 and 9 of N602 is 0V).

14.29V, resulting in a stable magnetic field to adjust picture incline caused by geomagnetism. 6. VM circuit Basic principle: VM tone circuit uses VM tone coil to produce a magnetic field. When the circuit turns bright or dark, scan speed will also change. When brightness signals appear, scan speed will slow down to make the brightness signals stronger.
