Expert:  ITPeter replied 1 year ago.


Are any of the LEDs on the R-904N coming on at all?

Do you have a voltmeter available to carry out some tests?

Customer: replied 1 year ago.
no led's and no voltmeter, I think I should just return this to the distributor.
Expert:  ITPeter replied 1 year ago.

The most likely cause of the fault is a faulty power supply board or faulty switch, but testing would be required to confirm this.

Thanks for the info. I will try to replace it.
