Watch the following images showing Xhorse Dolphin XP007 Needle Leveling not light up.
Xhorse chief engineer replied:
If Dolphin XP007 is within the warranty period, please contact me to confirm whether it is the problem of the screen, the continuity or the sensor harness.
In fact, it does not affect the usage.
Just confirm that the milling cutter and probe are attached to the fixture during leveling.
