Dec 30, 2008 - In my case, the monitor was fine for the first two months. But then started making a buzzing noise... 1) when on, 2) worse when .... my Samsung TV ismaking high pitched noises even if its turned off. I will NEVER EVER EVER ...
Is the sound coming from the speakers? (do you hear it with the sound turned off)
Either an audio problem if heard only with sound up or if a buzz with sound off it is a coil or transformer on the circuit board vibrating hard enough to produce the noise.
Both are fixable but require different tactics to resolve.
Check your power supply. Take it apart and see if the compositors are all in good shape. If they are popped, puckered or oozing stuff out of them then you are going to have to replace your power supply. It also could be a bad inverter. Is there a buzzing noise before it shuts down? Has been doing it for a while and now won't come on at all now?
It ur Vizio tv,The power supply board is the problems.The transformers in the power supply board have gaps in the transformers.The high voltage curents flow that make that buzzing noise.
