My guess is the bulb isn't inserted correctly (it is a bit of a faff) or the new bulb is faulty.

Will try again. The bulbs are a pain to take out, whats the best way or tool for doing so please

A straw or a small piece of rubber tube.

I Can’t really advise on what’s the best tool as I used a needle nose pliers, in the course of all the fiddling, trying to remove the bulb I broke the solder connection on the circuit board, the bulb sits in a little box or pot, which is soldered to the PCB, pictured below. If you can’t get the bulb to illuminate then this might be the problem.
