I am having a bit of trouble with a desk lamp purchased from Ikea back in 2002, similar to this:
It was fine for a few years and then began to make a buzzing/vibrating sort of noise which got progressively noisy until you gave it a quick knock in the base which would quieten it down.
It was no longer needed for a while anyway but now I need it and it still makes that noise.
Is there any way to stop this noise from happening? It seems to be coming from the base which I presume houses a transformer as the bulb is a 20w type which runs on 12v DC. If you hold the lamp upside down, the noise completely disappears.
Sorry if this is a repost.
