MC28M6055CW Microwave Not working

[njjn]

I have a Samsung Combi Microwave model MC28M6055CW.

Tonight, for the first time in 3 years, it stopped working - or at least won't start. 

Wanted to use the normal microwave, as usual, but when I press start, it doesn't run.

None of the 'combi' functions work either - I've barely used them, so don't know if this is related or they've been like that for a whle.

There is power.

I tried all the basic things, but would appreciate any ideas or tips.

Thanks
