Problem with RGBW bulb

Hello. I have a problem. Sometimes green color is just White light. It works sometimes but sometimes all I get is white instead of green. Also the color combinations that uses green are messed up. I reset the bulb so many times and nothing. I think it’s a hardware issue?

From your description, it seems that it is most likely a hardware problem.

Hi, thanks for your reply. I assumed so too
You think you can help me out a bit more? Where can I get the bulbs layout or schematic? I might try and fix it. And an electric student at the moment lol

I don’t have the specific internal circuit diagram here. It would actually be difficult to repair it.
