There is harness connection between HD1 on the Front Panel LED Board and HD8 on the Tilt board. This connection affects both the Status and Lamp LEDs on the front panel and the temperature sensors for the Lamp Blowers.
Check this connection if you see that the Status and the Lamp LEDs are both off.
If this connector is not attached, the temperature sensor won't detect an overheating inside
the head that could crack the gobos.
