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.

Buzz When I plug the tv in I get a buzzing sound and the power button does not light up and there is no picture or sound.Could it be a tube?

I will guess you remember tube sets from our parents days !
They stopped being Mfr'd in 1972 !
Best solution for your set = replace horiz transformer and
transistor with RCA part # 's 257807 & 237470................T.

Buzzing after 1 hour

Is the buzzing coming from the back of the TV, staying loud even when the volume is turned all the way down, or is it coming from the speakers?

Buzzing noise with no picture or sound.

The power supply is telling you that it has a short. I think you have a bad high voltage transformer in the horizontal deflection circuit. I've repaired several RCA's with this very same problem. The newer RCA's are vert prone to high voltage transformer failure ! Stargazer

Buzzing sound

the horizontal output is shorted ,has to be replaced BUT solder all connections for three inches around the this horizontal and solder them well or the output will blow again,there is especially a small coil in the drive line to the base that causes most of the problem
