No heating, hot water?

My Ideal Mini C32 Combi Boiler has shut down. Boiler does not fire up when I turn on any hot taps....no heat from radiators, I don't see any pilot light burning , I do not have a " User's Guide " to find out how to go about re-igniting the pilot light (if that's what you do . This seemed to start only recently after I had tried to bleed the house radiators and found that 2 of them gave out nothing, neither trapped air or water. Anyone help?
