    We have a fancy bathroom mirror with LED backlights

    Its got 16 LEDs group in groups of 4 running off mains transformed down 24dc.

    Now some of the LEDs have gone so a row 4 doesn’t work.

    If I bridge the duff LED the 3 remain come back.

    So I can solder in new ones I just have no idea how to work outr which ones I need.

    They are white, have a small square base approx 3.5mm x 3.5mm with 4 pins and a dome top???

    Help!

    check for defective or dry joints first.

    it is unlikely that the leds have gone
