Great clip. No unwanted comments and/or ghastly music and just the information required only. Very well done. Just subscribed. Thanks.

As soon as you are able, I would recommend (my personal opinion) changing the capacitor to 120uF and at least 500V and ideally 750V if it will fit. 400V (which is high anyway, I would also check the bridge) on a 450V capable cap is a bit high and probably contributed to the failure. Also, some heatsink compound on the MOSFET.

I tried looking for a higher voltage cap, but the formfactor does not fit (unless I bodge it in from the side). If you look closely there is some fresh compound, but it's the new-fangled silver stuff (4.8 W/M-K) so it looks almost the same colour as the heatsink itself. Good tip on checking the bridge!
