You might want to try the Class X 0.1uF capacitor. It's C38 on a 120v board. Also there are two Class Y 4700pf capacitors at C33 and C37.
However, if you have a 230volt board, the Class X 0.47Uf is at C37 and the two Class Y 4700pf capacitors at C33 and C36.
IMPORTANT NOTE - These capacitors must be the appropriate "Class" for their purpose. "Class X" must be replaced by "Class X" and "Class Y" must be replaced by "Class Y".
The originals may be termed as "self - healing" but at this age, many are beginning to reach the end of their workable life, causing momentary shorts across the mains input.
Class Y are supposed to 'fail safely' (since they are designed for line to chassis) but who knows what happens when they reach their end of life as they age. Class X will short across the line and can cause fast breakers to trip.
When purchasing, I would HIGHLY recommend getting them from a reputable dealer and not from cheap ebay sellers. These are a safety rated component for good reason. Also, you'll be looking for Class "X2" or "Y2" - the most common for household electronics filtering.
Both should be rated at 250Volts AC or 275 Volts AC, and will be marked with all sorts of safety & compliance bodies.
LATE EDIT - Make sure to get ones that have the correct lead spacing and size for the board.
