26、k When repair is going to be attempted in the set that uses relay circuit in the power supply block, electric potential is kept charged across the electrolytic capacitors (C101, 102) even though AC power cord is removed. If repair is attempted in this condition, secondary defect can occur. In order

27、to prevent the secondary trouble, perform the following measures 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

28、 end of the discharging resistor to the positive (+) side (+VH) of C101. (For two seconds) 4Contact the same end of the discharging resistor as step 3 to the negative (-) side (-VH) of C102 in the same way. (For two seconds) 5Check that voltage across C101 and C102 has decreased to 1 V or less using

29、 a multimeter or an oscilloscope. Select a discharging resistor referring to the following table. Note: The reference numbers (C101, C102) of the electrolytic capacitors can change depending on the models. Be sure to check the reference numbers of the charging capacitors on schematic diagram before starting the discharging work. 2. Check items before exchanging the MICROCOMPUTER Be sure to check the following items before exchanging the MICROCOMPUTER. Exchange the MICROCOMPUTER after confirming that the MICROCOMPUTER is surely defective. 2-1. Regarding the HOLD terminal of the MICROCO
