Have you ever found that your electrical circuit board suddenly starts to give off a ‘buzzing’ sound?

Ours did – yesterday morning. Rather terrifying when you consider that the board may be embarking on the earliest stages of blowing up. Expensive!

A dear Friend Paul B. in Melbourne (his only problem in life is that he barracks for the Richmond Tigers – Go Pies!), told me a few years ago: “If something happens, it will have happened to someone else before!”. He’s right and so I’ve learnt to find sites such as www.fixya.com which normally provide the answer.

so – to the web. It was one of two things – a lose connection in the circuit board and the prelude to it blowing up. Get an electrician fast!

The second, is a strange one……the new bulbs (halogen, eco, etc etc) that we all use these days as we endeavour to Save the Planet, never actually turn off and they give off a magnetic field back to the circuit board. Now all this is fine unless the bulbs are not screwed in tightly (even if they work as they are). This field creates a buzzing sound and, eventually, damage to your board.

Ah! Madame’s new chandelier had just been installed in the doll museum and, lo and behold, the bulbs were only fingertip tight, not real tight. I tightened and……no more buzzing!

Thanks Paul! Now say slowly after me, “Collingwood, for ever.”
