The following components were removed after inspection and shall be replaced:

2x 22pF Class Y
3x 0.1uF Class X
2x Resistors
2x 220uF Electrolytics
1x TRIAC – This was not faulty but the legs snapped on removal of the clamping bolt.
1x Inductor – Just for inspection.

The failed resistor had become quite hot and burnt the top of the PCB. I cleaned this with a fiber glass pencil and applied a couple of coats of clear nail varnish afterwards.

The back of the PCB shows some signs of the burning but it is still intact.

Above is the damaged capacitor next to it’s new replacement.
