Location of Transformer in Dolphin Power Supply

Hi There,

My Dolphin has stopped working and have gone through the complete unit with multimeter testing voltage and continuity on the cable, Amphenol plug and incoming power. I have confirmed that the power supply is bad as I had a new power supply and the cleaner works with the new power supply. My question is where is the transformer located within the power supply and what are the exact steps to perform with the multimeter to determine if the transformer is bad or if the PCB is bad? I have tested that I have 120V going into the power supply and 0 Volts coming out of the power supply, I do have continuity on the Amphenol plug. Attached is a photo which may help. Any assistance would be greatly appreciated!

This is a Switch Mode power supply, chances are rare that you can repair it unless you have massive Test Equipment.
If you wanna give it a try places to look are,
Bad cap's, burnt ressistors etc.
If a new psu is to expensive, you could buy somerhing off The shelf, shouldnt be that dificult to find One with The right spec.

Doubtful the coil is bad

The transformer coil with copper wire windings rarely fail. Most likely an electrical component on the circuit board.
