As "Good Luck" says, this site doesn't sell anything and I can't work out what made you think it does.

Its unlikely you have three duff transformers but if you can use a meter they would be easy to check.

I agree with "Good Luck" that the fault is probably with the lights although his description of all the lights in series is probably wrong. (300 LEDs in series, each dropping 3 volts or so [depending on colour] is about 900 volts!). I would hazard a guess that the lamps can flash and the control box has failed or possibly part of the cabling between power connector and control box.

Kevin - this is not a retail site - no selling on here...

Have you considered that you may have three good transformers and one set of bad lights?

I suspect that the 300 LEDs are all in series - if one of them should fail then no current can flow and they all go out.

But I could be wrong - you may have three bad transformers.
