A few trig LEDs flicker during startup

Hello all. I bought a used DN recently and noticed the LEDs on the tracks, fltr, amp &lfo buttons, arrows and also some of the sequence trig’s flash on then off.

This happens before the boot splash screen. Everything is normal after that and the DN seems to work fine.

Has anyone had a similar experience? Should I be worried of a potential failure in the near future?

Also I’m on 1.10 but I noticed it before I upgraded. The person who had before me hadn’t updated at all.
