hello
i bought this,
http://www.ebay.co.uk/itm/PCB-LED-0...054158?hash=item43de84cd8e:g:dIYAAOSwBahVf9Qv
put it together following the schematic and it doesnt work. i am using a 19v 3A laptop supply though. and it says 24v input.
is that why? i thought that you could use any dc supply, the output would be limited though if not 24v.
also, i am not to sure how to test this to find where the fault may be. any suggestions on testing a circuit?
thanks
simon
