Hello all,
I've just plugged in a SPARCClassic to 240 V 50 Hz AC (brought it with
me from a 60 Hz country).
Despite the power supply being rated for this, it won't start in the
traditional sense of the word. The speaker makes a clicking noise
when I press the power button and until I turn it off.
Inside the case, everything appears intact...
Thanks,
- Alex

Hello all,
I've just plugged in a SPARCClassic to 240 V 50 Hz AC (brought it with
me from a 60 Hz country).
With a SMPS, the AC will hit a bridge rectifier after passing a simple
filtering network. I would be very surprised if the frequency is your
problem.
There may be a switch or jumper for mains voltage, but if this is
incorrect you would probably know about it by now.

A hiccuping SMPS. There could well be a fault within the SMPS its self.
