I bought a color changing LED light kit for my basement and found out it wasn't long enough so I bought another. I connected them together with an LED amplifier and it seemed to work perfectly. Except when I came back the next day to turn them on again, they didn't work. I found that I needed to unplug the PS and re-plug it and viola, the lights worked again. This happens every time now when I want to turn them on. I've replaced the PS with a spare and it's the same results. I'll mention that disconnecting the PS from the LED controller does not fix it, it has to be unplugged from the outlet to fix it. Anyone know where I might be going wrong?
Here are some links to the components I used:
