Philips PLCYC-1 Color Issue

[JVV]

Hello,
I noticed today that my five Philips PLCYC-1 LED CYC units all behave nicely except in the Blue color range. The 5th one on the chain tends to look more green. Even though the color profile on the ION's monitor gives all the same numbers. This doesn't happen when I pick any other color except on the Blue/Green line.

Any thoughts?

Does it do it if it's the first light in line? Is it maybe in a different channel mode? Maybe an LED or several went out?

I had a similar problem a few years back. We had nine PLCyc1s and 1 was noticeably more green. We just customized our palettes to compensate instead of looking into repair.

It does stay more green than the others even when at the front of the daisy chain. It looks like its running the same channel mode as the others. Is there a way to tell if an LED went out just by looking at it?

You may have to do a little disassembly to where you can look at the bare LEDS. Then just bring up each color a couple percent until they're just starting to glow. You should be able to see if anything is not turning on, especially if you compare it to a known working light.

I think the PL series has calibration in the fixture to match different LED batches.
