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 MICROCOMPU
19、TER 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 MICROCOMPUTER When the HOLD terminal (INPUT) of the MICROCOMPUTER is “H”, the MICROCOMPUTER is
