Flashing spotlights then dead

[Yeeha28]

I have six GU5.3 spotlights in my bathroom. One of them occasionally started flashing and, one day, it tripped the fuse. After resetting the fuse, only three of the lights are working. See photos.

I checked the lights by swapping the spotlights, and they aren’t faulty. I wanted to access the transformer, so I pulled out one of the non-working lights, but that was as far as I could pull it out as seen in the photo.

Any advise please.

It is common for one power supply to run a number of lights, and it would seem odd for a fault on a lamp to cause an MCB to trip, I assume that is what you mean, fuses rupture they don't trip.

So it would seem likely a power supply has failed. It would seem likely the power supplies are near the centre of the room, where the ceiling rose was, so that is where I would look.

Have you changed any lamps recently?

I've seen those lighting kits before and they have a 60VA supply so each lamp cannot be more than 20W.

Often, these lamps are replaced with 35 or 50W units, this overloading the supply.
