need LED help

[hoonderific]

So I had my blue leds go out after overheating (son unplugged the fan) I have replaced 2 of the contollers but there still not turning on. When you try plugging them in nothing happend and nothing else will work but after things reset the fan and the whites still work. Any clues or maybe someone I can pay to help?

I'd assume the bulbs are fried. It could be the driver, but I'd place money on the bulbs. Do you have a multimeter?

 

[hoonderific]

yes how would you measure it to see?

If the bulbs are getting power then bulbs are burned if not its the driver, right?

 

[hoonderific]

part of the driver was melted thats why I replaced those

usually overheating will kill the bulbs not the driver. do you have one of those LED tester? i get one everytime i order LEDs from rapidled. have five or six laying around.

 

[hoonderific]

No I bought it already setup

You test the LED by placing one end of the multimeter in the positive, the other on the negative. Do you see any voltage going through it?

Ok I will check..these ones have potentiometer could that be the pproblem? Also I thought these drivers had a ssomething to switch the lights off before they would overheat

well I havent got around to trouble shooting my blues and now I lost half my whites they flicker when I unplug them so it cant be the lights. I am so lost I did pull out my multimeter finally but they all seem to be reading pretty much the same stuff
