If repair is attempted in this condition, secondary defect can occur. In order to prevent the secondary trouble, perform the following me

22、asures before starting repair work. Discharge procedure 1Remove the AC power cord. 2Connect a discharging resistor at an end of lead wire that has clips at both ends. Connect the other end of the lead wire to metal chassis. 3Contact the other end of the discharging resistor to the positive (+) side

When the above described phenomenon occurs, it can lead to wrong judgement as if the MICROCOMPUTER is defective and to exchange the MICROCOMPUTER. In such a case, perform the fo

26、rced-reset by the following procedure and check good or no good of the MICROCOMPUTER. 1Remove the AC power cord. 2Short both ends of the electrolytic capacitor C113 that is connected to VDD of the MICROCOMPUTER with tweezers. 3Connect the AC power cord again. If the MICROCOMPUTER returns to the norm

27、al operation, the MICROCOMPUTER is good. Note: The reference number or MICROCOMPUTER pin number of transistor (Q110) and electrolytic capacitor (C113) can change depending on the models. Be sure to check the reference numbers on schematic diagram before starting the discharging work. 2-3. Confirmati
