LED on power button is lit solid, but no video.

This is a common issue with NUCs, and it frequently ends with NUC being recycled.

The generic video troubleshooting recommended by Intel generally doesn't resolve the issue.

• Intel NUC powered on, but no video using HDMI, DisplayPort or mini DisplayPort

Try:

• Try different port on the NUC (display port, HDMI, thunderbolt
• Try different video cable, different monitor
• Update the BIOS
