Constant buzzing noise

I have been told by two techs that the packaging of the tv at sea level then shipped to our high altitude was causing the buzzing and that now new procedures are followed.  What can we do to ensure our tv doesnt go out? We purchased it here in Colorado Springs for use here.  Can a part be replaced to stop the buzzing and keep the tv under warranty?

Emerson tv problems

If you are using a cable or satelite box, the problem could be from mismatch of the volume level between the TV & the source. This is solved by properly adjusting the 2 volume levels to eliminate the buzz.

The issue could also be either your speakers or Input/Output PCB.

Also be sure it is coming from the speakers.There have been some issues of buzzing caused by vibrating transformers on circuit boards,

How do I stop the static noise from my vizio tv?

At high altitudes all plasma tvs will emit a high pitch noise.
There's nothing you can do about it besides move or get a new tv. Plasmas just do this.

Buzz sound when tv is on constant

Hello; If you have a plasma TV, is fairly common to hear buzz noises. They can be always there or intermittent. They can get louder as the screen gets brightest. If the buzz is noticeable when you are at normal volume setting, the buzz is excessive and a PCB probably needs replacing. These buzz noises are almost never a sign of failure or safety. LCD TV's can also buzz, but the same applies. John

Below is an image of rear side of your TV, Sony KDL-40W5500
Top right corner is marked there and possible cause of noise seems back light inverter board, there are high voltage going to CCFL inside LCD panel and seems high voltage leakage causing that buzzing/ fuzzing noise.

Replace back light inverter board upon voltage leakage confirmation.

High pitched noise

I am about to post a in depth guide about how to fix this problem. It's because a capacitor inside the TV has blown which causes the buzzing high pitched noise. It's really easy to fix however and only costs about £1 / $2 to sort out.

You can read a similar guide here but I will shortly be uploading a guide on the buzzing problem!

Plazma TV buzzing noise

I have the same problem I can hear buzzing over the volume of the tv into the 30 range. I've had a tech out 3 times and he's coming out for a fourth. He's changed to power supplies and is bringing the 3rd next visit. From what I've read it has either to do with power supplies or grounding strips.

Humming noise

Most times a humming noise in a Plasma tv is associated with high altitude. If you live over 3500 ft. and when you first turn on the unit is has a slight buzz and it gets worse as it warms up then you have what is referred to as high altitude sickness. You shoul contact the manufacture with this problem and the should exchange the unit with one tested for proper operation at high altitude. If you do not live at high altitude then there is a problem in the unit that should be diagnosed.

Constant humming/buzzing noise

I purchased a poloroid tv 3732 in may of 2005 from circuit city, after about 14 months the set began making a clacking sound and humming sound that gets so loud it is unbareable. I have to turn the set off. I have found out I am not the only one with this problem that has a poloroid tv. I had a technician at my home that told me there is a service warranty on these sets because the wrong part was used and the part needs to be replaced.
