LED Strip lighting

[Maroochy]

I have installed LED strip lighting behind some landscape panels. There are 7 panels each panel having 2 x 1200mm 2538 LED light strips. I have two power feed lines - one powering the furthest 3 panels, one powering the closest 4 panels to the power source. The power source is a 22amp 320 watt LED driver. I tested the system with a battery - all lights worked. Hooked up the LED driver - all lights worked - initially. Now the 3 string doesn’t. What is the likely cause?

My suspicion is a bad connection in the wiring.

I've had problems with the connectors on the ends of strip lights. My symptoms were similar to yours. Soldering is reliable, but the clamp-on connectors can be flaky, even from good brands.
