We have several low-voltage LED light strips in our light-up cabinets in the kitchen. They have all worked fine for 3 years. One of them has now started to flicker for a couple of minutes when turned on. After that it goes back to steady light. If I turn them on/of they all come back fine so it is only one out of more than 10 strings that behaves like this. They all have individual low-power converters so I assume I can switch two converters to see if the problem is within the light strip or converter. It is just odd that it started after 3 years, with no changes related to the power supplied in the house/kitchen area. Any idea why this has started? I assume the low-voltage power supply is most likely the problem...?

  • Hello, and welcome to Home Improvement. Your idea of swapping parts is probably the way to go, but other than that we can't really figure out what's wrong from here. – Daniel Griscom Jan 12 at 14:44

Most likely, it's the converter

Those are electronic power supplies, and they are made in China. Fortunately they're also commodity items. If you want a more quality version, try looking for a "meanwell" brand.

It might be the wiring, and that is a serious fire-starter problem at any voltage, but that's not likely if powering off/on fixes it.
