why would my hotpoint TDC770 die?

Hotpoint TDC770 been working fine for a couple of years....part way through morning today, noticed that the unit was dead, Socket checked ok, fuse ok, took the back off the unit and all seems well - no signs of blockage anywhere.
The unit just seems to have no power going through it - no lights coming on at all, and nothing happening....can anyone advise me please? (and not just to buy a new one :P )
