Buzzing noise on Mitsu 82 inch... Has anyone else had this problem?
1683524
I have the 73" version of this TV that I received last week, and the first thing I noticed is how silent it is. I don't hear any fan noise (or other) unless the room is dead silent and I go put my ear up to the back of the set... and I can hear just about every noise there is. My Plasma TV on the other hand has always drove me nuts with the notorious Plasma buzzing sound. I love the viewing angles, inky blacks, and smooth, even back-lighting of my Plasma, but I am ready to give that up for the size and silence that the Mitsubishi provides. You may want to get your TV checked by a technician if it's still under warranty.

Is the buzz only through the TV's speakers or is it heard no matter what? I have a soundbar and will shut the TV's speakers off. Im really interested in this TV.

That's kind of what I had. But it wasn't a steady buzz - more like a loud 60 Hz humm. I even tried to move it as far from the TV as I could. I was thinking there was some sort of interference, and separation might help. But no. Amazon is great about returns. This is first time I had a problem with a purchase.

The buzzing is only present when the backlight is less than 10. I believe its the flourescent bulb buzzing similar to when typical flourescent bulbs are used with a dimmer. I haven't found the sound to be any louder than the fan/hard drive in my Tivo so I'm not worried about it.

Probably a connection issue with one of the components hooked to the TV (mine happened to be a Sony DVD player...) removed that and the hum went away. Gave me an excuse to get a progressive scan DVD player... hooked it up and still no noise. It took me a bit to narrow it down, since I've got so many console systems. ;)

I have not had any issues with mine. Some folks reported issues with buzzing, but was related to the speaker not being tightened down correctly. Buzzing without your bass plugged in sounds like a ground loop problem. Have you tried powering it from a filtered source? (I use a Furman PL-8 which was already inmy guitar rack)

No, thanks goodness, I've not experienced it having a buzzing sound. I know the annoying sound you are talking about because I getthat buzz from a different type fluorescent fixture in my laundry room.

We do not have any buzzing at all from the cable. It works wonderful and is clear with the sound. We are using only one cable and have not attached a second cable to it. we have the cable attached from a computer to a TV 20 feet apart and it is as clear as if we had no cable and using on the TV. Depending on what device you are attaching the cable to if it has a gain button you might try adjusting the gain. or you may have a bad cable and need to return and replace it. Hope this helps

I bought a 50" 8UK Pannasonic tv a few years back. It had the same problem. So I exchanged it for another one. It also buzzed, but less so, so I kept it. Today, 3(?) years later, it still buzzes - especially on white or bright scenes. I'm seriously considering one of the 42" Panasonic plasmas for my bedroom, but am leaning to an LCD because I really don't want any buzzing/background noise in that smaller room.

I have the same version but with a metal chassis and noticed this whine. I'm going to look into a replacement. It makes the noise about 20 seconds after plugging in the power.

ok. Got the replacement.1) the static sound still exists from 1-8 but it's half as bad as the previous unit2) now sometimes i get a buzzing sound when the volume is at 0This one was also manufactured in October 2010.I'll see if this bothers me enough, else i'll send it back.

Hi Kevin, I have experienced this noise. I bought it brand new and returned and exchanged it and the second television did this as well. You can read my comment on the comments page. Did you resolve this problem? CJ

I haven't noticed any buzzing at all. It's in a lamp beside couch. I think would notice if it was an issue.

Same issue from my LN46B750 The speakers were replaced along with the mother board....no help. Still on startup....especially after sitting for a while it will buzz for a few seconds and then go away. Have it plugged into a protected power strip.

I'm not sure. Our tv was not making any noise. It simply would shut off. After looking online at different forums, I was able to determine I needed a fan replacement by the number of times the red light near power button would blink. The fan fixed our problem and tv does not shut off anymore. If your buzzing noise is coming from back of the set and not speakers, it most likely is the fan. There are forums that say u can use compressed air to try and clean out the debris...but we found it was only a temporary solution and buying the fan was worth it! I recommend you Google "sony buzzing noise" to see what others say. Hope this helps! I'm not sure. Our tv was not making any noise. It simply would shut off.

I had this humming/buzzing noise problem when I bought Samsung 21". The monitor started humming after it was on for 5 minutes. It was not loud, but annoying. I returned it to Costco. Don't know what problem that was.

The "buzz" is a fan and you have to be right next the TV to hear it - if the fan on your laptop does not bother you this won't either. If it is louder than that you should return it - its broke....
