Question about JVC AV-30W475 30" TV

Loud Buzzing Noise

Recently my JVC TV began buzzing very loudly. I tried adjusting the sound settings, along with doing a brightness test to see if it was a coil responding to AC current. Lessening the brightness and changing the settings hasn't worked. When I mute the TV, the buzzing drops about 50%. It seems to be getting worse daily. Can someone please shed some light on what is causing the buzzing? Thanks so much to whomever can help!

TV making loud buzzing sound

More sets than you might imagine have this kind of problem---I a regular TV it is usually a transformer that is vibrating hard enough to make the sound---the higher pitched sound is just that--a sound.

If this is a direct view(means not a flatscreen and has a Glass Picture tube it will be either the high voltage transformer or one of several smaller transformers.

This can usually be fixed---seen a few so loud the cats in the house run away.

Let me know model number of set for more information.

On chance it has the high voltage transformer I attach a photo of what that looks like.

A loud buzzing is coming from the back of my sanyo ds 25390 tv. picture and regular sound is fine

If it is a high pitched whine or buzz it is likely a transformer vibrating so hard it is making the noise.

There are ways to try to deal with this issue but the set has to be opened and probed to locate where it is coming from--

for example with back off and set on a plastic rod can be used to touch areas and exert slight pressure until the sound changes or goes away--then either replace the part or I have used hot glue etc to stop it.

You first have to locate the source of the issue:

find where it is coming from.

TV Making a Loud Noise

this can happen with the flyback transformer's brightness which can be adjusted , also the power transformer can make humming or buzzing sounds which can't be adjusted , also this can happen with the picture tube or the CRT board failing , and sometimes chips with heat sinks or the IC's themselfs

Sanyo tv ds25390 buzzing sound

I had the same problem with the same model.
The solution was to replace a capacitor, C622, which is located near
a small blue rectangular plastic component.
This component is a relay that is controlled by C622. I paid $2.39 for
the part, $8.99 for S&H for a total of $11.38. This fixed my problem!

Buzzzing sound

That's called your secondary and it a feedback you're hearing probably because the HOT is shorted... Unplg the unit and do a continuity test on the horizontal output transistor - in particular E to B and if you get infinity that's your trouble.

Have the speakers ever been played loudly? They may have been pushed passed their capacity, in which case, it may be time for a new tv.
