Ipaul - thank you very much. Will try it out.

It is such a loud and nerving sound - damn I am going crazy :)

Best

Well, i'm a bit unclear which coil you're referring to but anyway: i think this tv has an Avant chassis.

I also think you're not annoyed by the 15KHz noise as any crt tv has this 'whistle' but weak and high so barely/not audible for the 'grown-up' ear, but sometimes one of the linearity coils or deflection coil or HT transformer may start to whistle/resonate at a much lower freqency.

If it's one of the smaller coils or HT transformer sometimes sodlering a few of the connections while pushing it a bit sideways may help (to change the 'phisycal tension') or sometimes maybe a tie-wrap arond it.

There's no 'miracle cure' just like that, it's a bit of trial and error or....just order a new one and replace :)

Hi Peter,

Whilst I am unable to help I'm sure this post got lost in the speed of the forum so hopfully one of the regular (super) tech guys will assist now I've bumped it for you!

MX 8000 - noise from the linearity coil

photoplay — Tue, 05 Jan 2010 10:55:03 GMT

Hello,

Hope that some one clever can give me an advice. :)

I have a MX 8000 who makes a noise like 15.625 khz - when I tap the chassis it is possible to kill the noise but after a few minuttes it is back again.

I tried to open the coil and to put a little nail polish on. But still the same problem. :(

Any suggestions ? Because it is really annoying.

Looking forward to hear from you guys.
