Hi, I’m Louie. Sorry you had to wait awhile but I’ll do my best to help.

Initially, depending on the version, check if it has a voltage setting at the back as it may be configured for 220/240 VAC operation.

Still, the described symptoms almost always point to an internal hardware issue. More particularly, potential suspects after a review of the schematic diagrams are:

  • • faulty V801 vacuum florescent display (least likely);
  • • failed primary transformer ATS1205 (likely);
  • • low or missing secondary voltages ±69V, ±38V, ±25V among others (most likely).

All of the above would require that the unit be opened up for visual inspection, voltage/continuity/resistance checks, confirm faults and effect repairs.

Are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
