Backlight high pitched noise A couple of months after purchasing this TV, a high-pitched noise started to appear. It gets louder when the backlight setting is turned up. It sounds like "ringing" in the ear. It was determined by a service technician to be a defect in the LCD panel, which was replaced. However, the noise persists. I've tried plugging the TV into a wall outlet vs. a surge protector. It didn't make any difference. The only way for the noise to be inaudible is to turn the backlight setting to 2 or less. Does anyone know what could be causing this noise? Backlight high pitched noise A couple of months after purchasing this TV, a high-pitched noise started to appear.

I have a 37" Magnavox and I thought the noise was just due to buying a Maganvox rather than a Sony or some other popular name brand. Turns out I was wrong I guess. Either way the sound makes me want to kill myself and I just might if it persists for much longer. Someone please post something that will describe a way to make the ringing stop, before it's too late.

Hey Jwag, did you get the TN-T2653H by any chance? I just got it a couple days ago, I also noticed the high pitched noise, and it seemed to be related to how bright the screen was (ie. when programs showed bright shots and when the backlight setting was set to 10). Did Samsung tell you anything relevant?

Sadly, I was lazy and never called for service or changed backlight:( BUT, it is my second tv now for treadmill room only and cannot hear it over the hum of treadmill.

I just bought a new SONY KDL32EX523 and it has this too, except that the noise is loud enough on all backlight levels to be heard all the way down the hall! The sound absolutely would want to make me kill myself if I had to live with it every day. I'm just waiting for Amazon or Sony to get back to me otherwise this is going back.

I have a brand new Sony KDL-37W5500 that has the same problem: backlight "whine" when the screen is predominantly dark. I have tried all possible backlight levels and the problem persists on all of them (but setting 2 minimizes it). When I have the volume low at night this whine cuts through and is VERY noticeable.I have emailed Sony customer support about it - if it can't be fixed I will look elsewhere for a TV...

I have the same problem! This has really been bothering me, especially when it goes in and out. I am going to try to change the backlight and also notice if it has something to so with it only happening with bright shots.) Since it is under service warranty, I definitely plan to call the service repair number. Did any of you call for service? I will check the model of my 40" sony.

I'm having the same type of noise problem with a 26" Samsung. It was like that straight out of the box. The backlight was set on 10 (in the Dynamic picture mode) I have to keep the backlight setting at 5 or below and then it's masked by the TV volume. On mute I can still hear it. Very annoying. I'll be contacting Samsung very soon.

We just received out Samsung 32 inch TV and after reading these posts turned the back light 8. It worked for awhile but I think there is something wrong with these TVS. Anyone have anything else to try

You have a part going out on it, I had the exact same problem and it was more to get it fixed than it was to buy a new tv. I don't remember what the part was but it was expensive. Mine started doing that right after the warranty ended, and they won't fix it for free. Good luck with it. And I would stay away from their products in the future

Mine too, after about a year. Seems to be common for this TV. Mine could not be cost effectively repaired.

I just got delivery on my PN50B860 and no buzzing. My guess is that given all the negative publicity that it is fixed. No problems and the flat panel is awesome! Try contacting Samsung technical service to confirm as they should be able to inform you if the issue has been resolved.According to a Samsung customer, (http://reviews.us.samsung.com/7463/PN50B860Y2FXZA/pn50b860-50-1080p-plasma-hdtv-reviews/reviews.htm) the buzz issue cured and there is a tech repair sheet out from Samsung to fix it so the newer TV's should be fine.

I have been using my model for 2 months now and no buzzing noise can be heard, I tried to figure out a way to adjust the brightness, but there is none...

Yes, I am having the same issue with my same model television. Mine was purchased the end of 2/08, it started doing that about a month ago and it is out of warranty. Have you had your repaired? If so, what was the cost? wants $150 just to come out and diagnose the problem.

When I called tech support back in October, they described the functionality as I stated in my earlier post. I guess I got lucky and got a tech that knew what he was talking about.I am, however, getting a intermittent popping noise now from the rear of the TV... It has always been there, but it finally started bothering me enough. My local warranty service provider will take my TV set again this evening to attempt to fix the problem. Evidently there is a new kit for it.

I have not had that problem, sorry hope you find out what it is, maybe its normal for your TV.

Sorry I can't help you. This TV barely lasted a year before the sound went out and we pitched it. I wouldn't recommend this TV to anyone!!!

Do the lights show that the bar "thinks" it's off? (ie, it really does turn off). There are some wires connecting this to your audio source - if you disconnect them, does that cause any change? (also, as with any electronics, you might try unplugging, wait 20 seconds, then replug in). I can't think of a good reason for such a noise other than the unit dying, but these things might prove it.

I just received delivery of this same Sony last Friday and have noticed the same thing. I have not done anything about correcting it because the delivery man who helped me secure the TV to the pedestal stand didn't think there was anything wrong. This isn't much help, but it's all I know for now.

I purchased a refurbished one in December for about $1,200 including the shipping. When the tv arrived the power cord was not in the box. Samsung did send another one in about two weeks. Then when I got it hooked up the tv made a popping sound. The good thing is it was under warranty and it was fixed by replacing the main board. There were no cosmetic blemishes on the unit when we received it. If you don't mind having couple of possible problems, it will save some money. Other than that it is a great tv. Hope this helps with your decision.

I've read other reviewers comments about exactly that, a high pitched whine like a camera flash charging up. All I can say is the one I got is perfectly silent. I keep it on my nightstand and have never heard anything.

I got a Samsung technician came to my house to fix this crackling noise. He also said he never heard this kind of problems from Samsung before. He changed the power supply, but the crackling persists. He then rescheduled for a new panel. A different technician came with a new panel and replaced it with the one on the tv. Now my tv has much less crackling noise. Maybe one or two pops only, but its manageable for me.

I just received this toaster from our wedding registry and YES my husband and I both hear a high pitched noise. I don't know if it is normal or not - came here to see if anyone else had the problem.

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.

When the TV it's off it is completely silent. However, as soon as the TV is working you can hear that "buzzing" sound just right out of the box. It is not extremely loud but did bother me.
