Led Strip Controller broken after terminal touching

Hello all,

I hope I am posting in the right category.

So I have a problem with an LED controller (amplifier). I have this LED controller: Touch! Wireless RGB LED Controller - aspectLED

What happened is that i connected the led strip to the terminals of the controller as they should be, but accidentally some of the pins touched with eachother (i don’t know what to what something like green to red or blue to red). Since then, my controller is kind of going crazy. The controller is not responding to any of the RC commands from the touch controller, it only displays the green color. If I circle between all the modes and the colors, i kind of get multiple shades of green and red, but nothing more. Simply red or blue i cannot get, and also the on / off commands not working anymore.

I also have 2 other different controllers, and surprinsingly enough, one of them is doing the exact same thing, but the other one is working perfectly, so i know for a fact that this is not a stip problem, but a controller problem.

I also tried to pair the remote controller to the rgb controller again as i have an option to do this by pressing 2 buttons from the touch remote simultaneously, but with no luck. The led from the controller seems to be lighting 2 times and this indicated that it is re-paired. But i still have the same problem.

Does anyone know what happend and if i have any sollution to this?

Thank you!!

Hi Andrei,

Unfortunately, if you’ve shorted pins on your controller, you may have permanently blown the components, responsible for switching the LED channels on and off (MOSFETs, or the components attached to them). They move a lot of current in your case (4A per channel), so even a short period of contact could be enough to “let the magic smoke out”

I have shorted a fan output on a 3D printer control board in the past, and it killed the board instantly. A better board may have isolated the fault to the MOSFET driving the fan, but in my case, there was no barrier and it took the whole thing down.

If you’ve confirmed that the fault is in the controller, and not the strips, I’d say a replacement would be the go, or perhaps opening it up and looking under a microscope for the damaged component and replacing it, but for the price, I’d say a replacement seems like the more sensible option.
