I have just had a bulb stop working I assumed it was dead, but when I replaced and put it back ito the flush downlight casing it did not work. I took it out and refitted it but this time left it hanging on the twin flex it came on but every time I fit it back in it goes off again. I can't work it out and can't get in too far to see any cable problem - it does not make sense it has worked for years and now will not work - any ideas i.e. could it be the two pin connection?

Yes.
You can replace the connector, replace the whole fitting, or get something long and thin and have a poke around in the holes which the bulb go in incase it's just a bit of dirt getting in the way.
Remember to turn the power off before trying any of these.
