Nothing? Walk through this list
Most “dead strip” moments come down to one of these. Go in order — you’ll usually find it before the bottom.
- Output not muted — Settings → Hardware → Connected. Make sure the device isn’t silenced.
- Rescan — click ↻ in the Devices panel after plugging in gear or installing a driver.
- Device in the tree? — expand device and channel; Identify flashes that channel on real hardware so you know you’re looking at the right row.
- Components assigned — empty channels need something from the Component Library or RGB Wizard.
- Eye icons — device, channel, or component might be hidden on the canvas.
- Effect running — pick an effect; make sure Pause is off and Brightness isn’t at zero.
- Right Scene, right tab — load the Scene you expect; check the active canvas tab.
USB and “something else owns my controller”
Other RGB apps love to grab USB devices and not let go. Close them, then try again.
If USB access is blocked on your PC, running RGBJunkie as Administrator once can help (not everyone needs this).
Unplug, replug, Rescan. Classic, but it works.
Our supported gear list shows what we test most often.
WLED and network strips
Network gear has to be added and reachable — see WLED setup. Double-check the IP in plugin settings (gear on the device row).
Still stuck?
- Settings → System → Logs and send a support report
- Tell us the device, your RGBJunkie version (Settings → About), and whether vendor software lights the same hardware at the same time
