[Important] Caution after the repairing
!
COIL drive circuit has the defective
r
If the voltage on pin 5 of IC7002 (LDO) does not reach 3.3 V, replace the IC7002.
r
If the clock on 4 pin of IC7003 (LOGIC) is not 8 MHz, replace X7001 (Resonator) or IC7003.
r
If the clock on 8 pin of IC7004 (LOGIC) is not 2 MHz, replace IC7004.
r
If the clock on the gate side of Q7003 (FET) is not 2 MHz, replace IC7006 (LOGIC).
r
If 2 pin of CN7003 dose not have 2 MHz half-wave waveform, replace Q7003 (FET).
!
Confirm the signal (JOG_SW) on 2 pin of CN7002
r
When the jog is touched, the JOG_SW signal changes from about 0.5 V (touch off) to about 1.5 V (touch on).
If the signal has any problem, replace the JLCD Assy, the COIL2 Assy, and the COIL1 Assy in that order.
