I am repairing a Korg AGX100G. The LEDs under the display have become dim. I read that I need a cold white 5050 LED. I bought MP-5050-6100-57-80 but it’s rated at 18 volts and once I had the device apart I see that the old LED runs on 2.9 volts. Which one should I get?

TIA

Welcome to the forum.

Oops you bought an LED element meant for general lighting like in household light bulbs.

Here’s a search result that returns all the in stock White 2.9V discrete LEDs, the type used for backlighting displays. Unfortunately I could not filter by shade of white color so you’ll need to read the data sheets to find out the wavelength.
