REEBOK ZR-Lite Treadmill - no power

[RJ8672356]

Hi all, new here! hope someone can help,

My Reebok Zr-Lite treadmill suddenly lost all power, no display, no sound, nothing... I used it the day before and it was fine and next day completely dead.

I've checked the circuit breaker with a multimeter, no blown fuses and the power lead/socket are also working.

I removed the MCB and reconnected thinking of a loose connection but still nothing. Also there is a LED on the MCB which doesn't light when powered.

I'm not sure if the fault is in the MCB or elsewhere.

Any advice would be appreciated

Do a little reverse-engineering of the AC in circuit and see how far the input power goes for starters.

Thanks for getting back
Sorry could you advise how to best do this? I'm not an expert with using the multimeter, much appreciated!

Trace from the AC terminals and sketch a bit of a diagram as you go.
Typically it leads to either a bridge rectifier for DC or a single diode and large electrolytic capacitor.
