Presumably you have already opened it up and checked that the power is getting through the power board to the power board outputs. If not, you may have to trace it forward from the power input socket to find out why not.

This is difficult without a schematic but unless you can spot an obvious problem, heat stressed or burnt components or blown (or bulging) capacitors etc, then point to point testing with an Ohmmeter, (disconnect the power) or a Voltmeter (if you know what you’re doing - be aware of lethal voltages etc), and drawing the circuit as you go, is the only way to find out what is happening.

Hi @a1tinman ,
