Hotpoint HTC6T Cooker hood both lights not working

I tried to take out the whole light fitting to change the bulb (even though it doesn’t look like the bulb has blown) and now the fixture is loose so I think it needs replacing too. The strange thing is that both bulbs stopped working at the same time. I can’t see where the switch or transformer are in case the issue is with them.

I will try and help with this problem HOTPOINT CH Cooker Hood HTC6T FP2009 (CC 063134)

the first thing you need to do is check the voltage going to the bulb using a multimeter, if you have the correct voltage then it will either be the Transformer is not working oh you have a problem with the printed circuit board. The printed circuit board sometimes can be an easy repair as it may have only blown a track or one of the switches is faulty if you have soldering capability this may be an easy fix
