Buzzing TV (- giving me a headache!)

    Hello all,

    I've a tv at the moment that I'm using and its started buzzing at a very high frequency. Its unbearable as it gives me a headache after a while, which is a little bit of problem when trying to watch tv!

    Any ideas? I've wanted to throw a hammer threw the dang thing but I don't think this would yield good results.

    Many thanks in advance.

    I know the noise you mean and it's a real pain in the face. Worse is old people (and young who use walkmans a lot) who can't hear it. I presume your TV is not under warranty otherwise you'd have brought it back. For some reason, Philips tv sets like to do this; guess philips sucks a bit more these days.

    Anyway, it's likely the flyback transformer which will resonate at the horizontal scan frequency, likely about 15kHz. Like a buzzing PC or fridge, a bit of pressure at the right point can help - even pressing or lifting on the cabinet at a corner might stop it. Fixing it properly would require either replacing the part or supressing the vibration with hot glue. Or superglue maybe. A good tv repair shop could do it for you or you could do it yourself. PS: A TV has 10s of thousands of volts running around it, so don't freaking die...

    Thanks for the reply.

    TV is a Sanyo, funny enough. Not much experience with 'em, but this isn't great. And yeah out of warranty.

    I'll try the good old fashioned hit with hand hard method! Or maybe the lifting.

    Don't think I've the expertise nor b^alls to open a tv with said thousands of volts going thru it!
