need help with light

led light i bought isnt working hoping i can fix it... only issue is i have no idea on the lights model number all i have is pics of the components model numbers and info and a description...


problem is the white lights flash on when you plug it in with the blue lights then they all turn off for a second and the blue only comes back on.... white stays off. i think i need a power supply but which one and where can i find one that will work... tried searching the model numbers but came up empty

not sure why it uploaded the pics twice...

Return it, it's a broken piece of shit.

Unfortunately the goof won't take it back. Trying to save it rather than throw it out... just need new power supply or driver I think. White and blue have their own dimmable controls and power supplies and if I disconnect the blue and hook up the white they work so ya... worst case I'll hook up the white alone just loose half the power that way

Hoping someone with led diy knowledge can help out

The other guys are right about the quality of the light. With that said, I can relate to your attempt to make it work. I have some experience fixing the old blurple Epistar lights. My bet is that it's not a driver. Most likely it's a single blue diode that has burnt. The way I have found a burnt diode is simple. First I look for that appears burnt. It may be a little darker than the others. If I find one, great. If no, I remove the board so I can access the leds directly and CAREFULLY jumper around each diode (positive to negative leads on the led), one at a time, while it's powered up until it lights up. When it lights up, I have found the open diode. Your jumper should be a short piece of insulated wire in the shape of a horseshoe, with ends stripped back a small amount. When you find the dead diode, you may be able to de-solder the connections and replace it using fresh thermal paste. Some boards have the diodes reflowed (soldered) to the board which means they are tough to replace. For a simple and easy fix you can take your test jumper and solder the jumper to both sides of the dead diode to complete the circuit. You will lose the light from that one emitter but the driver will be able to handle the lower voltage draw for a single diode. That may not be the case if there are many more bypassed.
