VR-1 is the varistor and that will have mains voltage on one of those broken legs. The large resistor is a 600-620 ohm 10 Watt resistor.
Was the varistor on the board before you started troubleshooting ?
As Ralph suggests, there could be a serious underlying issue that needs to be resolved before moving on.
I haven't done anything to that area and I got it like that. It has never really worked properly from the outset so it looks like I will to get a new rectifier?
Doesn't look that complicated - unlike the solenoid board that I resoldered the pins on. Maybe I can just get parts??
