Re: Television problems

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.

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.

Loud buzzing sound on Sanyo AVM 1909

I had a problem like that so I disabled the tv's onboard tuner (input source)and now we use the cablebox's video and audio out to the video and video in jacks on the TV this will work as long as you have a cable box or sat reciever for your video and audio source and of course your TV must have video and audio inputs so it will work.

Good luck Rich

Loud buzzing noise when turning on

It sounds like a bad internal connection or a component failing. If the picture still is very good take it to a known good repair shop.

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!

Hello to all you buzzers, I have the answer to your problem. First this is what's happening. The buzzing is coming from the power relay. It vibrates at 60hz because the power supply filter capacitor is not doing its job hence you have a rough d.c. pulse going to the relay.To solve the problem remove back of t.v. slide circuit board out (you will have to disconnect white wire from degauss coil,located on left front) look for a blue box approximately 3/4"x1 1/2" this will be the power relay. Now look for capacitor location #c622 near the relay. This capacitor should be 470uf 25v. Remove and replace with 470uf 35v capacitor, connect white degauss wire temperarily put back on and give it a spin. Hope this solves all the buzzin,robert
