Buzzing Beovision 3

13 replies

My 5 year old BV 3 has started to make an intermittent deep buzzing sound. It seems to come at random and irregular intervals and seems to come from behind the brush aluminium plate. It's not coming from the speakers.

Any ideas what might be wrong?

 

Is the Beovision 3 working correctly other than the deep buzzing sound, in particular is the picture perfectly correct ?

Phil,

Good, well the following additional questions come to mind on this one:-

  1. You say it is intermittent, but does it happen a lot after you have just switched the set on, or is there a period of time before it starts?
  2. You say its seems to be coming from behind the brushed aluminium plate, can you please clarify exactly where you think the buzzing is coming from.

Thanks for the quick response.

I'll check out the answers to your questions tonight.

If it's only when powering op it's the degauss. But don't think it's that you mean. If I'm right it comes randomly when there is white on the screen! it happens because the tube use more power then normal, and there comes a 50 Hz buzzing sound from a trafo in the power supply, that also gets the plastic cover to vibrate, 🙁 very bad... there are 3 things to do... change the tube [:'(] or spay paint the power supply with lacquer... or ignore it... sorry

(seen 3 that has done this, change tube in 2 of them and spay painted the last... this is not a problem in avant because it made of wood)

Buzz is not when you first switch on.

Sound comes from the base of the set, not the screen or the speakers.

I'll check to see if it's linked to white on the screen, but it does sound like what your describing.

Can you explain why/how sprying the transformer helps please?

 

Thanks to both of you

You can try to disconnect the RF antenna. I have the same problem with my BV3-32 (5 years old). 🙁

I think the problem is in this way.
