Only 1 RGB strip out of 4 works after firmware update.


Recommended Posts

Till 2 days ago... everything was fine.

Then I got a firmware update for my Lightning Node and iCUE update.


And this is what I ended up with:


I have 4 RGB strips connected to Lightning node pro link 2.

The effect runs for around 2 minutes and then 3/4 freeze.

So i have LEDS in order 1-2-3-4.

When it freezes:

1 - works

2 - freeze

3 - freeze

4 - freeze


When I unplug them and plug them in, only 1st one works.

When I change to 2 strips or 6 or 5 or whatever still only 1st strip works.


Restart doesn't help. Strips are stuck even during restart.


My 6 x LL120 Fans on Link 1 are working fine...


Now I wonder... anyone else have an issue like that?

Maybe someone has an old firmware for Lightning node?

Is there an option to go back to previous version at all?


I really hope so, because we all spend a lot of money to have things like that and having an issue like that makes my blood boil.


Thanks in advance for any response.


PS. Reinstalling iCUE didnt help, i got into same situation just right after.

Hi DevBiker,


I've made my tests. I turned off the 1st strip. The 3 were working without any issues for few hours now.

I connected then the 1st strip as 3rd strip.

If You can imagine the 4th LED strip froze.


Anyway I've contacted Support to get a replacement.

The faulty strip has also 2 leds not working and 2 stuck at one colour.


Thanks for suggesting me to swap them.
