Hello, Since a while I suddenly have a problem with my blinkstick. When I switch off the led’s or choose the color black the leds are not off but displaying a faint blue color. All other colors seems to work fine but this problem also appears in the ambilight feature and thus are dark images resulting in a blue ambilight. I played a bit in the settings but no succes. See the attached images for a display of the problem. ![off](https://forums.blinkstick.com/uploads/default/original/1X/f57e40e76074bcca650f5bbad6231e05997d78d0.jpg) ![on](https://forums.blinkstick.com/uploads/default/original/1X/8603024a499a86e66e8b5295b971b54a4c4b1edc.jpg) Best regards, Joost ---

I’m using Philips LEDDC12v2.3w RGB lightstrips with the original Philips powersupply. The strips and powersupply are directly connected to the blinkstick led adapter board. No additional controller/electronics are used. This worked fine in combination with the Blinkstick earlier. ---

Im not sure about that, maybe you can post an image of how you have connected it excactly to your LED adapter. I had problems with missing GND or wrong wired LED strip. Maybe you´ll find something helpful here: [Pro led Adapter with Dioder](https://forums.blinkstick.com/t/pro-led-adapter-with-dioder/365) ---

Ah wait… you have the Inverse mode. Switch the mode to RGB in the client and see if it will change something. In your pictures I can´t see if the wiring is correct. But please try to change the mode first. ---

Yes, inverse mode is configured since the beginning. Worked good before. RGB mode gives incorrect colors. I tried again but still incorrect colors. When I use turn off in RGB mode the led’s stay turned on in yellow color. De cable is connected as follows: ![20180105_131710 (Medium)](https://forums.blinkstick.com/uploads/default/original/1X/c9d0bc02dda88ac3e8b148927522add7dbae2341.jpg) ---

Incorrect colors in RGB mode means incorrect wiring. The “black” wire says to me that this is the GND and not the VCC. I need to know more about the device itself but I would recommend to use the RGB mode and put the black wire to the GND pin. This should be the base for further analysis of your problem. ---

I would like to try your suggestion but my led adapter board doesn’t have an GND connector i’m afraid. ![20180107_142517_resized](https://forums.blinkstick.com/uploads/default/original/1X/0341327c5232e9bd3b04fd4c177b000bd31ddaa9.jpg) ---

Take a look at this post: [Pro led Adapter with Dioder](https://forums.blinkstick.com/t/pro-led-adapter-with-dioder/365/44) But I would prefer if @arvydas could give an official statement if this can work.
