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
