1.Model Name:
AR-M351N/M451N & ARM351U/M451U
2.Symptom:
The variations of jumper cables that are used on a high-voltage transformer PWB often
cause noise generation (cut dimension). If a noise is generated, a PCU PWB malfunctions
when the front cabinet or left door is opened or closed. This malfunction may cause
symptoms such as E7-90 or machine power on/off.
3.Description:
To prevent the PCU PWB malfunction, we have changed the high-voltage transformer
PWB so that the PWB is not affected by noise. Along with this change, we have also
changed the parts code of the high-voltage transformer PWB.
Identifying new and old high-voltage transformer PWBs
4.Action:
From mid-May 2006 production
Power on/off operation caused
By pcu pwb malfunction.
