Precaution to replace Optical block
(KSS-213F)
Body or clothes electrostatic potential could
ruin laser diode in the optical block. Be sure

NOTE ON BEFORE STARTING REPAIR

25-48 100 3 87-A00-247-090
49-140 220 5 87-A00-232-090
Note: The reference numbers (C101, C102) of the electrolytic capacitors can change depending on the models. Be sure to check thereference 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 confirmingthat the MICROCOMPUTER is surely defective.
2-1. Regarding the HOLD terminal of the MICROCOMPUTERWhen the HOLD terminal (INPUT) of the MICROCOMPUTER is “H”, the MICROCOMPUTER is judged to be operating correctly.When this terminal is “L”, the main power cannot be turned on. Therefore, be sure to check the terminal voltage of the HOLDterminal before exchange.When the MICROCOMPUTER is not defective, the HOLD terminal can also go “L” when the POWER AMPLIFIER has anyabnormalities that triggers the abnormality detection circuit on the MAIN C. B. that sets the HOLD terminal to “L”.
• Good or no good judgement of the MICROCOMPUTER
11111 Turn on the AC main power.22222 Confirm that the main power is turned on and the HOLD terminal of the MICROCOMPUTER keeps the “H” level or not.33333 When the HOLD terminal is “L” level, the abnormality detection circuit is judged to be working correctly and the
MICROCOMPUTER is judged to be good.
1. Forced discharge of electrolytic capacitor of power supply block
When repair is going to be attempted in the set that uses relay circuit in the power supply block, electric potential is kept charged acrossthe electrolytic capacitors (C101, 102) even though AC power cord is removed. If repair is attempted in this condition, secondary defectcan occur.In order to prevent the secondary trouble, perform the following measures before starting repair work.
Discharge procedure
11111 Remove the AC power cord.22222 Connect a discharging resistor at an end of lead wire that
has clips at both ends. Connect the other end of the leadwire to metal chassis.
33333 Contact the other end of the discharging resistor to thepositive (+) side (+VH) of C101. (For two seconds)
44444 Contact the same end of the discharging resistor as step33333 to the negative (-) side (-VH) of C102 in the same way.(For two seconds)
55555 Check that voltage across C101 and C102 has decreasedto 1 V or less using a multimeter or an oscilloscope.
Select a discharging resistor referring to the following table. Fig-1

In such a case, check also if the POWER AMPLIFIER circuit or power supply circuit has any abnormalities or not.
2-2. Regarding resetThere are cases that the machine does not work correctly because the MICROCOMPUTER is not reset even though the AC powercord 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 MICROCOMPUTER is defective and toexchange the MICROCOMPUTER. In such a case, perform the forced-reset by the following procedure and check good or nogood of the MICROCOMPUTER.11111 Remove the AC power cord.
22222 Short both ends of the electrolytic capacitor C113 that is connected to VDD of the MICROCOMPUTER with tweezers.33333 Connect 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 dependingon the models. Be sure to check the reference numbers on schematic diagram before starting the discharging work.
2-3. Confirmation of soldering state of MICROCOMPUTER
Check the soldering state of the MICROCOMPUTER in addition to the above described procedures. Be sure to exchange theMICROCOMPUTER after surely confirming that the trouble is not caused by poor soldering but the MICROCOMPUTER itself.
