I guess I should have been more specific (many LED stripes do include groups of serial leds plus resistors designed to be powered at 12V or 24V).
This type of supplies [www.ebay.com] is what I am dealing with for RepRap use. Most of them work ok for me, but from time to time I get a defective unit. When that happens I try to repair it if possible. If a component blows up then it is easy to spot, main switch or dead output diode are the usual suspects, but this time all looks nice and clean.
