Don't know 'why' it's failed - could be the cap itself or 'something

I'd put money on something else, looking at the cap wires, the burnt
board, coloured deposit and general sticky yuk of the board particulary
top right corner. I'd say some liquid has got in at some point and caused
a flash over between the pins of that C.

It appears it may have worked for a while but now the fuse blows at switch
on. Suspect a knackered SMPSU, so probably require a new pair of driver
transistors, the control IC and other sundry bits to get back working. If
it takes more than a morning in total to repair it's not economic, there
are other reasons for fixing things besides money though.

Also - the cross-hatching on the PCB indicates (I think) areas which
are 'live' and can bite - so take care....

Yep down to the left of the big C below the burnt one are the words "LIVE
PART ..." The diodes look to be 1N4006, rated at 800V. Bite with a capital
