High pitched buzzing...

That is probably the flyback transformer and may be dangerous to service by yourself. Get a pro to look at it and stay safe. Voltages inside TV sets can exceed 10,000 volts AC.

If it whines when moving and not moving with the engine running,it may be the fuel pump.

Hello, I hear this constant high pitched noise, almost like ringing, but even ... pitch

It's likely a capacitor associated with the power supply having gone bad.
It's obviously beyond your expertise to repair it yourself.
Find a trustworthy repair shop and take it there.

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.

If the whine changes pitch with engine RPM it could be a serious problem with the alternator. Possibly the voltage regulator, or a shorted diode in the alternator causing high frequency AC to be fed into the harness.

1) Make sure valve is open all the way 2) some machines have a screen inside of the hose hook up which could be clogged. 3) last check to see if it is the hot or cold by switch your selector switch on your machine to hot then cold. If one of these positions eliminate the noise then the valve in the machine is bad.

Hi Pullerwife,

I have a few suggestions for you,

First of all, check your air filter, make sure its clean, not clogged, and doesn't need to be changed.

I don't know how handy you are, but if you are fairly handy, check the idler pulley bearings, if your not, have a shop check it out, as a last resort.

Power steering pump/fluid being low is also a possibility, but thats usually more of a lower pitched whine then what you describe.

You say once the vehicle is warmed up, the whining stops. Does Weather seem to be a factor as well?

Hope I've helped, and don't forget to rate.

I have the same problem like yours but what i did is to replace the alternator and now its so quite no more high pitched sound. You may used belt stress fluid but its only last for few seconds then sound comes again. I replaced it with refurbish part alternator.My sienna 2005.

sounds like bad solder connections on ground of the inputs radioshack has a cheep solred gun and solder make sure set is unpluged
