Samsung LE40A656 constant high pitch whine?

[coanda]

Hi,

I Turned the TV on this morning to be greeted by a high pitched whine/whistle/squeal. It only happens when the TV is switched on. Not on Standby. Obviously I've tried the classic 'unplugging it and plugging it back in'...no joy!

It seems to be coming from the panel itself as the pitch of the whine changes with what is on the screen. Odd!

Does anyone know how to solve this??

Its just over a year old years old now so I hope it isn't terminal!

Thanks

I thought this happened on all TVs?

Genuine thought - I cannot remember a TV where this didn't happen. I have a Sony CRT, a Tosh CRT, a big Samsung plasma, and a 2000 vintage Panasonic plasma which is still rocking on although it is bloody noisy. That said the picture is still awesome.

Then one day you realise it - and you can't stop hearing it.

Plotloss may have a more technical theory though.

It may well do....but this is unacceptably loud. I noticed some distortion of normal tv sound this morning so I shall try some different speakers tonight...

Is the current passing through a mouse...?

If only it were that simple....the cat removes that possiblity!

Sound is coming from top left hand corner as you look at the screen.
