Internal red LED1 stays on

I just finished cleaning my galvos and mirrors, plugged everything back in and was about to do a laser test when I noticed a red glow inside my machine. re-opening the back the red LED1 (as marked on the PC board) stays lit after power up. Any idea what this indicates? I am fairly certain that this did not stay illuminated before.

galvos crossed?

I double checked the plugs on both the galvo side and PCB. They look correct. Still scratching my head…
