Question about Philips MCM570 CD Shelf System
The standby light comes on when the power cable is plugged in, and it just clicks about every 3 or so seconds, i think this might be because i was looking on the back of it and saw a little switch that canged the voltage, and i flicked it to the lower voltage setting while the stereo was on. (it does the clicking while on the original setting, and the lower setting also) any info on fixing this would be much appreciated!
You have been very honest and told us the facts behind the fault, thanks for your good fault description...
Now what you have done by flicking that little switch is:-
Altered the input power design of the stereo system.
The switch is there so that the user can connect it to either the USA power supply of 110-120 volts, or connect to the Australian/New Zealand power supply of 230-240 volts.
When you turned the switch over you lowered the input to 110-120 volts yet it was still plugged into a 230-240 volt power supply.
This has blown a component inside the power supply and
now it must be replaced.
This is a specialised replacement process by a service man..
The clicking sound is made by the internal power supply (Its called a switched mode power supply) and it has detected the blown component and it is trying to reset itself automatically for you, but it cant because of the faulty component.
Its very clever in its design and if it wasnt clicking there would have been quite a loud 'bang" and a lot of smoke when the switch was moved to 110-120 volt position.
