check all connection

check you have mains voltage on the board

make sure all your solder joints are ok and you have not damaged tracks

if it was me i would check for voltage both on the high voltage caps whicH should be 300v DC ( be careful( and the low voltage caps ( probably 12VDC ) but only if you are competant and safe

Thanks Dave, I was up until midnight fiddling with it!

Some or the pads were damaged when I removed the power chip but I’ve exposed some of the relevant tracks and ensured I soldered onto them so I’m quite confident with that, I’ll get my multimeter out and check for power supply, I’m guessing the main switch supplies the board so that should be what I check first? I don’t think I’ll fiddle around with the capacitors though if they are energised!

There’s no power going to the main switch

[electrofix]

well that may be it

you need to check power is getting in the machine first

check socket plugand fuse

I got the fusible resistor from RS Components who didn’t charge me £6.95 for delivery in the end,…

How did you get the postage reduced as I need a couple of parts from RS and object to paying £6.95 for a package that’ll likely cost them about £1.50?

I just ordered it expecting to pay the £6.95 but they never charged me for it, so not sure if it was a mistake or they just felt bad!
