Question about Sanyo DS25390 TV
The tv is only 5yrs old or less the buzzing noise continues even when you try to turn down the volume
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!

TV is making a loud buzzing noise while volume control does not effect the buzzing sound.

I have found with many televisions that a buzzing noise that changes with the brightness of the screen is usually caused by dust on one or more of the toroidal transformers. Take compressed air and blow it through the air vents at the back of your television or to do a better job you can open it and then blow it out.I hope it helps

The blue part which is buzzing is a relay made by OEG, part number SDT-SH-112DM. It is controlled by the capacitor at C622. I have replaced the capacitor with one of a slightly higher rating as recommended but still have the buzz. Unfortunately the relay is an obsolete part and is very hard to find, at least at reasonable cost. I've read that these coils rarely fail but it looks like modification of a similar relay may be the answer.

Copper wire coil under white plastic cover was the source of my set's buzzing. One application of nail polish to the loose windings of this coil three months ago solved problem AND led to clearer picture.
