Welcome to just answer.
What is the exact model of the system?
Do you happen to have electrical measuring instruments? I would like to perform some tests using ohmmeter and voltmeter.
Customer: replied 11 months ago.
I think it's a 509. But unfortunately I have to go to work and will be unable to do anything for a week or so. I did check the fuse with a volt meter and battery. Not sure if power is getting to the switch.

You need to set the meter to measure resistance and measure across the pins ofor power plugeneration whole the system is off and disconnected from power.

We would like to see if the power transformer has continuity. I think the power transformer is the problem or the rectifier circuit need diodes replaced.

Ok, I'll try that. I'll need more info on where to check.

Also it may be a week or so before I can do it.

Disconnect the power plug and measure across the hot and neutral pins with meter set at 200 ohm scale.
