Display totally dead, good continuity into main pcb.
Customer says it is only a couple of years old, does this module suffer from the same faults that the Whirlpool boards did a few years back with a resistor failing?
you have to find the board power supply and see if you have got an output voltage.
if yes or if the voltage goes on and off its scrap new board need. if no power the board may be fixable
I brought the PCB home in the vain hope that I would be able to replace one of the box capacitor or voltage thingy, so how do you test it? (Edited this after googling – it’s the relay not capacitor that I was referring to.)
There’s no lights on the display and there is power going to the board but I do not know how to test it from the point of entry on the board to determine if there’s power or not.
