Fer Falcon no central heating?

Decided to put on my central heating tonight only to find out it no longer works, my hot water works fine but central heating isn't, I have reset the boiler and reset all the electrics but this has made no difference, I also noticed that the LED (Clock) isn't working, so I don't know if this could be a problem. The CH light dosen't come on. does anyone have any advice on how to to fix it.

Thanks
