Oops sorry!
So would that be the cluster of diodes under and around C51?

Tested all 3 times.

1 to 2 = 0
2 to 3 = OL
3 to 4 = 0
4 to 5 = OL

Diodes test.

Diode D14 = 555, OL
Diode D19 = 554, OL

Steve..

Triple checked, all readings were zero.

Steve..

I checked again in case I made a mistake but no, I had to set the meter to 200 as it displayed overload at 20.

Steve..

C53 = 35.6, with and without fuse.

6.19 on C51 and 1.2 on C56.

6.15 on C51 and 0.61 on C56.

Steve..

I get a reading of 13.2 on pins 5 & 3 and 5 & 4 of the PSU plug is that OK?

Steve..

OK I went for it and masked all but pins 5 and 2 which gave me a reading of 23.6, which I think is what I should get.
SO I assume the PSU is OK then. Tomorrow I'll have another go at removing the board for inspection.

Steve..

Call me Mr Thicko but I've studied the diagrams of the PSU plug and I still can't decide which pins I have to connect the multimeter to!

Also thanks Martin, I did try but it's well and truly on there and I don't want to force it too hard in case something gives that shouldn't.
