I have read in one review that when the tv is on there is a somewhat high pitched hum. Has that been your experience? Is it annoying? Thanks! -- Tom

I have not had that problem. The only problem that I have had with the TV has been the remote sometimes it thinks the keyboard is open so I have to slide it open and close it again. Not that big of a deal because I rarely use it but still annoying.

I have never heard a high pitch hum, I love my Vizio, also bought the Vizio sound bar only because I love the theater sound. It is a great TV and would recommend it especially for the price. I purchased thru Amazon, had it delivered and have been watching it every night. Really like a smart TV and stream alot. Vizio has great customer support too.

I have not noticed anything of that nature on mine and its over a year old now!

I haven't noticed any hum. The tv has been great. The only complaint I have is the speakers in the tv aren't the greatest but I use a sound bar. If your debating on getting this tv I would personally say do it. It was worth every penny to me.

Neither I or my wife have ever noticed any sort of noise at all from the tv.

I/we have no complaints whatsoever with this unit and would recommend this tv to anyone w/o any hesitation or mental reservation. The tv we have does not a hum, let alone any static that is noticeable. I would certainly recommend this product to my friends and family members!

The sound is really poor. One thing I have noticed is that the sound from regular DirecTV channels is much louder than the sound from HDTV channels or the one from the DVD or Blue Ray player. I have everything connected with HDMI cables. I tried also with optical cable with the same results. The volume difference appears also when I listen thru the Home theater. Does anyone know if this is normal?

No problem , it is an incredible set, don't worry about buzzing or burn in. It's a thing of the past, it will be the best tv you've ever seen.Let me know if I can answer any other questions i did allot of homework

I found that making sure there was no interference from any other electronics nearby helped. Just experiment with moving the unit, the input cable, and the source of your sound (whatever you're broadcasting) around until you find the sweet spot. I've got virtually no hum now, but occasionally I'll hear some and invariably find that someone has moved one of the elements around. Once I put it back where it belongs, no more hum.

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.

same here. Set up tonight. This background noise is annoying. Like nails on a chalk board. Sending it back. Hoping for better replacement. Shame...it looks good for my small home office (in a spare bedroom). I don''t need fancy, but I don't need this headache that this tv is giving me.

I just recieved the TV and after connecting it, I immediately noticed a high pitched back ground noise that is always present. It varies in pitch and modulation and seems louder on digital channels than analog channels but it is very evident on both. Is there any adjustments to be made or should I just return it?

Mine does not have this high pitch you're talking about, just a loud hum, rather like a window air-condition unit. Since it is in my basement, it does not bother me. Maybe you have a bad unit?

I have owned this tv for about 3 weeks. Picture is great, only issue is volume kicks off every so often , thought it was the high def cable box so I replaced it but get same result, I plan on exchanging tv. Has this volume problem happened to anyone else?

I'm glad I found your post Alan... I almost sold this TV over the OPC issue. I found it terribly irritating, but turning it on and to 1 fixed it.

There is a buzz heard when directly in front of TV at any distance. It is NOT inherent in Plasma technology but specific to this model. To me it is extremely annoying. I heard it during normal programming at normal volumes. It is a design flaw in TV that has not been addressed and it is a total deal breaker for me. Your mileage may very but I'm not listening to that high pitched whiny noise on such an expensive television set.

I use a 35 ft. VGA/ audio cable from my PC with a PC/TV tuner, using it as a DVR with Windows Media center to my Big Screen and also use my Monitor with a VGA Powered splitter. Using a powered splitter because with out it I had lines on the TV, the powered splitter took care of it, but I also have a hum or feed back sound, can't explain it. It may be the same sound you have, if you get a answer to your question please let me know at DWB@socal.rr.com, Thanks Don

Hi Andre.That was a number of months ago - did they ever "update" the TV, and did that solve the "lip sync" issue? I seem to be very sensitive to lip sync issues- I notice them all the time - if any channel is off by a fraction of a second, it really annoys me.

I've had best buy out twice now. The first time to replace all the screws in the back of the tv and that helped for about 1 week and the buzzing or humming sound came back. Best buy came today and replace one of the boards on the tv and i'm hoping this will fix the problem.

Hi i just bought this tv and loved it until I turned down the volume and had the same problem. I am returning it unfortunately but for the price it is a steal :-)

I discovered that same hiss when my TV was connected to a DTV converter box, equipped with its own universal remote. I was able to eliminate the hiss by lowering the volume on the TV's remote. I use the converter boxes remote to power on and off the tv as well as change channels and raising and lowering the volume. Note that everytime the tv suffers a power interuption by either being disconnected or power outage, I have to again lower the tv volume (and raise the volume using the converter boxes remote
