Beaky,

I struggle to get the leads of the multimeter to all the legs of BR2, so thats why i seem to only be able to test AC (10V) at the top right, and +DC at top left (which is only 0.5V)

The two bottom legs seem just too difficult to get to when its in the machine.

F113 is definitely fine as i removed it to test it with continuity

I might just pull it apart again and quadruple check the traces

I have edited my above post with some things to check with the board out
this is what I added
Check that you have continuity from the - on BR2 to the - Pin on C5. Do the same with the + pin on BR2 and the + pin on C5. You will have to remove the board for this.
It sounds like you have a  bad solder through in the area u are working on. either on the bridge or the cap
