Hi Guys
That cap might have died and taken out the fuse, which would be great as it means everything else is likely fine.
A cap across AC should have safety ratings and/or be polypropylene, which is self-healing. The circuit will work fine without the cap. Overall reliability would be improved with a bleeder resistor across the first filter cap C202. You may need two Rs in series to have sufficient voltage rating for the resistors. They can be 330k or 470k metal-oxide flame-proof 1W each. This will drain the cap at turn-off and it will protect the bridge when you switch to stand-by.
Of course, we all know that the safest stand-by switch is the one disconnected or never switched off.
