Flickering when light turns on

[Drie3]

So I've got a wrgb1200, and for the last few weeks it starts to blink at the time its supposed to turn on.
Doesn't matter if I've got a ramp time on it or not, it just keeps blinking.
Sometimes it stops after half an hour but it kept on going today so I can't use my light right now.

So my question is, how do i resolve that issue

1. Check the power adapter, is there a tiny green indicator light? Is it stable or flashing?
2. In the app switch to Manual mode, press the “Off” button, could the green light be turned off?
