So yeah, my LED is dead

Title says it all, wont let me register the product for an RMA apparently its warranty is up. Maybe I’ve had it three years not sure. Green and blue LED flickers on and off and dim all the time. Red one seems to work well enough though. Any fix for this that I can do or am I doomed to look at this flickering light while I try to sleep?

Just cover it with electrician’s tape.  :)
