Blue LED not working on some keys. Huntsman Elite ~ Synapse 4

g, h, j, k, o, p, [, ], c, TAB, LShift, CapsLock, Del, PGup, Numpad4, Numpad5. All have the blue LED disabled. The first day i noticed i was able to get it to temporarily fix itself by unplugging the keyboard , restarting synapse 4, and plugging it back in. but since then this issue persists, i know these LEDs are not burned out. they are just software disabled. 

I've tried firmware updating and factory resetting the Hunstman Elite. But i wish not to uninstall synapse if i can avoid it. When synapse is off and the keyboard is on default spectrum cycling the blue LEDs remain disabled.

I am firmly certain this is a synapse issue but because my keyboard is out of warranty i was forced onto this forum instead of talking to a customer service person. 

Edit* Windows Dynamic Lighting is off, Razer is set to Chroma RGB.

If you’re 100% sure, that these leds are not physically faulty, then I’d try Synapse 4 Open Beta: 

 Before installing it do a clean reinstall:

  1. Uninstall Synapse
  2. Download & run this tool: https://rzr.to/Tf53xj to remove any razer drivers/leftovers
  3. Then restart your PC
  4. After reboot install Synapse again (as administrator).

On the other side you can also (without Synapse) - try the Windows Dynamic Lighting … or 3rd party app like OpenRGB: https://openrgb.org/

I have Huntsman Elite. Both Full release and beta show no issues on this device.
