LED Experts Need Help

[Dipan00]

So my LED lights were running fine one day then the next day my blue channel started malfunctioning. This is a Evergrow D120 unit. Issue is on the lowest setting it does not flicker but anything above that it flickers and intensity stays very low. White channel works fine. I have included a link with a video to show what its doing. Any ideas on whats going on?[video]https://drive.google.com/file/d/0Bw6iNpbPBYNoN1drTVdHakJZdjQ/view?usp=sharing[/video]

Most common problem is the dimmer knob going bad. If I were you I would solder in a new one and if it's still acting up, you at least narrowed it down but 90% sure that's what it is

Dylan I was hoping it was going to be that easy. I swapped the other dimmer switch to test to see if that was it but the switch works just fine. Any other ideas?

Do you have a multimeter? Check out his link. Sorry, I wish I knew more about these.

Its probably a blown driver, voltage regulator is probably toast. Can you borrow a spare from someone to try a different driver?

Test the leds. The way these fixtures are wired up if one led on a channel goes out the whole channel goes out. Tape together two AA batteries and solder up some test leads. Go to each led on the channel in question and if you find a bad one swap it out. Reefbreeders sells replacement leds you can use for this fixture. I have a bunch of extras, so if you're stressed for time, you can hit me up.

Most of the time it is the LED drivers/power supply, but you should inspect the LEDs also. However the symptom is more like the driver issue, just my opinion. Open it up and the drivers might be cheap to replace (Ebay ).

Thanks for all the great advice. Luckily my driver is still good. After a closer inspection it was one led that went out. My fixture came with a few extra so I threw a new one on worked like a charm.
