Hi M/D,

Some difficulty as you haven't yet stated a problem - perhaps it's one of those situations where a Moon lander is realised from car scrap.

Just a phart from British V1 mankind - and so forth - Chris.

Hi M/D,

Well said - you need to check where voltages disappear - If mains fuse if OK then usually the PFC lump is also OK. check voltage on Main (Big Black) capacitor (usually 350'ish) then get back to Quuq for Sparky's next advice - Chris.
