WRGBII 120 flickering green light (even when off)

[Paul]

Hi,

My WRGBII 120 suddenly started with flickering green light outside of the "on" hours.
Also when the light is on it has a small flickering in it.

But the worrying part is the flickering when its "off".
What could be the problem of this?
Green led on the powerbrick is steady

Bluetooth part doesnt have a LED or other indicator.
Both are still very hot by the way (see my older post about this) but that was "normal".

Please follow below steps to test:
1. In the app switch to Manual mode, press the “Off” button, could the flickering light be turned off?
2. In the app switch to Manual mode, press the “All” button, take a clear photo of the whole led beads panel. Unplug the light, take a clear photo of the whole led beads panel.

It could be a problem of the bluetooth controller.
When it's powered off, the photo is not clear, need to take a clear photo of all led beads. We need to check if the led beads panel has problem.

I had a similar problem with my WRGB PRO2. When it started it would happen during sun rise and sunset transitions. The red LED’s would turn on and sometimes flash on and off. At first, turning it off for a while fixed it. Then, it would happen even when off randomly with red, blue, and green. After troubleshooting, I discovered that despite the drip loop, condensation had gotten into the water- resistant connector on the Bluetooth controller. Corrosion had built up and caused multiple random shorts. I ordered a new controller and cleaned the contacts in the light’s connector with 99.9% technical grade alcohol and a fine horse hair brush. (Looks like a tiny paint brush.) Anyway, after cleaning and installing the new controller all works as intended now. It’s worth checking because the connector on my light’s wasn’t visibly wet on the outside.

thx.

Took the light of the hanging kit so i could slide out the diffuser panel to make the photos.
Couldnt find anything wrong with the leds itself (as far isi can tell). So i hope its just the controller itself.

Led beads panel has no problem.
Just replace a bluetooth controller, it got short circuit.

Thanks.

New controller arrived and it looks like its working again and stops the green light on powering up etc
Controller turns the light in to a "free upgrade" to the 10th anniversary edition. At least thats what the app/controller is telling
Funny thing is that the presets looks different in colours. So need to play with that to see if i can get a nice colour out of it

Your light is regular WRGB II, you bought the WRGB II 10 th Edition bluetooth controller, the light could be a little different from before.
