The Easy touch motherboard power connector 6 pin, should measure with 12vac, 18vac, and 24vac as per labeling.
If not then the transformer is not connected to 120 or 240 VAC. If there is power (120 or 240) at the transforner (measure at the wire nuts), then the wirings of the transformer could be open. Very rare failure, but you can measure the winding of the transformer for an open circuit.
Most likely a circuit breaker which does not appear to be tripped, but is... So that is a matter of checking power on both sides of circuit breakers.
