If repair is attempted in this condition, se

17、condary defect can occur. In order 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 t

20、re are cases that the machine does not work correctly because the MICROCOMPUTER is not reset even though the AC power cord is re-inserted, or the software reset (pressing the STOP key + POWER key) is performed. When the above described phenomenon occurs, it can lead to wrong judgement as if the MICR

In such a case, perform the forced-reset by the following procedure and check good or no good of the MICROCOMPUTER. 1 Remove the AC power cord. 2Short both ends of the electrolytic capacitor C113 that is connected to VDD of the MICROCOMPUTER

22、with tweezers. 3Connect the AC power cord again. If the MICROCOMPUTER returns to the normal 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 ref
