My Razer Megladon headset lights won't turn on
This is actually just the internal LED that has failed, I have seen it numerous times on this model. There is no simple way to fix it, you would have to pull apart the headphones and re-solder a new LED on the headphones. It's definitely not worth it considering the headphones appear to work just fine still.
Let me know if you have more questions about this, just reply to my answer here, but unfortunately there is no "simple" way to get those lights back on, they have essentially just burned out.
Thanks,

Razer Ultimate Blackwidow up arrow key is malfunctioning
This is going to sound really stupid, but if I was just having the exact same problem as you. I launched the Razer Synapse 2.0 program and save that my up key had a macro that did nothing. Once I changed that back to the default single up key function, it seems to be working fine.
