Display is buzzing

Just purchased a Thunderbolt Display.
Noticed after a few days that the fan isn't always running and that it is now buzzing. The display is plugged into a 15" MBP. If I walk away and the machine goes to sleep, when I return, the display isn't recognized and I have to plug the Thunderbolt cable back in-annoying. Anyone else have these issues?
I also run Parallels. I've read there may be a coincidence that this is occurring with Parallels, but these issues occur with the virtual machine shut down as well.

Are you using a case or something?
Do a reset (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears, ignore the Slide to Power Off that appears)

My display starts "buzzing" when I increase brightness.

My display starts "buzzing" when I increase brightness, but gets lower decreasing lights. It seems to be originated in the left down corner on the back side.
It sounds like an electrical short circuit. Shall be needed assistance?

Actually, Apple says to use the Disk Utility program on the installed system to "Repair Permissions" as the program uses a database that is updated to the proper settings for the version of 10.6 that you are using.
The original DVD may have 10.6.0 on it but the computer may be running 10.6.2
The original DVD doesn't have any changes in the permissions that Apple has included with updates.

There is also an Apple document that says that just about every warning you see in the window while doing the repairs should be ignored. I just uncheck the details box and wait for the "Permissions Repair Complete" statement to appear.

I don't know if a permissions issue is causing the video settings issue, but it can't hurt to run the program.
Zapping The Pram is also a powerful reset mechanism you can try.

MBP sent in for repair--trade displays?

I just had my 15" MacBook Pro sent in for the following:
- CPU Idle Whine
- Non 0 / 100 % Display Brightness Buzz
- Display Hiss (temporary fix was slight downward pressure on the display, above the iSight)
- Right Speaker Distortion
I posed the question to the Genius who was helping me:
"Could you leave a note for the repair technician to use a glossy display, if indeed they need to replace the display?"
You see, I bought my MBP before they had the option to ship with glossy displays, and after using my brothers MacBook, I was hooked on the qualities of the display.
Unfortunately, the genius entirely turned down my suggestion. He said that they always replaced things part-for-part, and that it was entirely impossible to even so much as leave a note suggesting this.
Any thoughts, or was my genius just giving me a hard time?

I have problems with the display and I bought it yesterday. I'm going to make sure I don't have to send it in since I bought this one to use while they're repairing the other one and I don't want to keep buying macbooks.

My iMac: Apple or Lemon?

I purchased a refurbished iMac from Apple last November and thankfully also purchased the Apple Care. Initial reaction... very pleased though the display really isn't 25 bit and can only fake showing millions of colors though that only comes into play on certain occasions.
My first problem was that the iMac buzzed after it warmed up and the display brightness was anything but the brightest two settings with the sound peaking at the middle brightness. Ok, a quick search of these apple support boards reveals that this is a known issue with some of the display power boards. Called Apple support, and they got someone out here quickly (I'm far from an Apple store but in a larger city). Almost fixed. The sound still occurs but is not as loud. I was willing to live with that (for now at least) but then came problem 2.
Problem 2. My iMac ate my CD. I was starting to install Aperture but the disk wasn't catching the way it should and pulling it in after a partial insertion. Thinking it may be a bad CD, I inserted one of my known good Photo CDs and thar she went. Into the computer, not recognized and no way to get it out though the optical drive kept trying to eject it every five seconds. Very annoying and scary to think what is happening to my CD. Back to Apple Care.
After talking with Apple Care, I realized I was going to Sacramento that evening for several days so I thought it may be just as good to take it to the Apple store for in-house service. Monday night finds me at the Apple store and we go over the problems. Nice but a no go. Because it was Monday night, the needed parts wouldn't arrive in time for my Thursday departure so it is back to in-home service.
The in-home service guy was kind enough to stop by late Friday for another service attempt. Apart comes the computer to replace the optical drive. Apple uses a lot of tape in their computer assembly which makes computer repairs a bit entropic (i.e. each repair makes the computer a bit more haphazard). Out comes the optical drive but no obvious way to get the CD out so we end up having to dismantle the optical drive and pry it open a little to get my photo CD. Whew.
Apple sent two parts for the repair. The new optical drive and.... drumroll... instead of a new display power card a power cord!!!! That was useless. So I still have the noisy display power card. Oh well, at least it all works now... right? The Mac guy reassembles the computer and we test the drive - not with my photo cd but with an Apple Developer CD. Drumroll....... the CD goes in but isn't grabbed so I let the Mac repair guy try. No dice. The disk goes in but is not read. Well at least this time the drive ejects the disk.
That's fine. At least I have a usable computer sans a working optical drive. But wait.... now that the Mac guy is gone the house is quite.... except for my iMac. The vide display still buzzes and I have a new iMac noise. The OCC fan is now noisy. (I determined it was the OCC fan by downloading smcFanControl and varying the speed of the different fans).
This is great. Every time I get my iMac fixed, it gets worse. Now I need a new video power card, optical drive, and occ fan.
I'm still an Apple fan boy (this is the first of six macs that I've had a problem with but sheesh, what ever happened to Apple design? Anyone else in the same boat?

I think at this point Apple will replace the Mac.
If the Apple Care Representative wants to have it repaired again ask politely to have your call transfered to a Customer Relations Representative. This will escalate your case to someone tasked with making you happy and should get the Mac replaced with a brand new one, based on other folks reported experiences. The key is to be syrupy sweet as can be with the reps, but firm in your request to have this resolved quickly and without any more inconvenience on your part. You have complied 100% with Apple's attempts to repair the Mac and now it is time for them to step up to the plate and make the purchase of a long-time customer right.
Good luck.
BTW - that one is a LEMON!

Feedback on current MBP quality and any news on "updates"???

I know there are lots of threads that discuss issues people have had with their MBP. I've read about display problems, buzzing noises, and the like. For anyone kind enough to reply to this, my question is whether replacement MBPs in the past month or so seem to have remedied previous issues you had? Are you just getting different MBPs that have the same problems? I'm also wondering if anyone has heard news of when the MBPs will get an update, despite being relatively new overall?
I'm asking because I will be upgrading my current iMac G5 to an intel iMac and buying a MBP, both before July. Just wondering if waiting another month or two might yield something with regards to quality... I know there is no way to know this, but input from folks on the above could be helpful. Thanks again for any feedback.

My only problem with my new MBP is the power adapter. It appears to be the pins. They're pushed in and it's basically useless. Apple is sending me a new one and hopefully it'll work this time. To be honest, I questioned this whole new magnetic adapter. It sounds great but ... Other than that, it works wonderfully and that includes using Windows XP on my partitioned drive. I also purchased the 20" iMac Intel Core Duo (Windows installed) and so far, it's perfect. One thing ... I am very impressed with Photoshop 7's performance on both. It's faster than on my G5 and it's not even Universal!

Macbook Pro Retina/Thunderbolt Display, Mid-2014 speakers buzzing.

I've had my MBPR since September, and had no issues until this year really. If I attempt to watch a video or listen to audio, whilst on FaceTime - the audio seems to buzz. I've never had the issue whilst on the macbook alone - only when connected through my thunderbolt display.
Any similar issues/fixes?

Hi nicicloud,
It's been a while and I hope you would still notice my reply.
I am having the same issue where Thunderbolt Display does not have HiDPI options in System Preferences.
I am using a 15" MacBook Pro with Retina display.
I tried a few apps, including SwitchResX.
SwitchResX do provide a few HiDPI options, but the one I wanted, 1280x720 HiDPI happen to be not working.
Can you try setting your TBD resolution to 1280x720 with HiDPI?
Thank you!
Btw, with the 11" MacBook Air, I didn't even need to download any app to enable 1280x720 HiDPI on TBD. A simply terminal command worked

27" LED Cinema Display – noise and buzz

Hello,
I recently purchased a second hand 27" Apple LED Cinema Display, and I now started to have some issues.
The first issue started today, it is some kind of buzz that comes out of the right speaker whenever I lower the brightness of the screen. I have about the opposite happening for other people – whenever the brightness would be above 3/4, a buzz sound would come up. For me it's when the brightness is below 1/4. The lower the brightness, so higher the pitch of the buzz. How weird is that?
The second issue is that, whenever a sound is played, some kind of white noise starts coming from I believe both speakers of the display. Even if I just adjust the volume on the keyboard (which makes a sound as well), this white noise would come up. It would last around 15-30 seconds, and then it would disappear. If headphones are connected to the Mac Pro, it doesn't happen (and it can't be heard in the headphones either). I once hooked up the Mac Pro to a Panasonic TV to test, and there was no buzz coming from the TV either.
Now I just noticed that the white noise is constantly here since the buzz appeared today (when I lower the brightness). Something is failing here I believe. It could also be the graphics card I guess?
Sometimes I get a very quick weird flash on the screen (black & white stripes I believe) for half a second, then they're gone. It's quite rare so it's hard to troubleshoot. Maybe it has to do with the Cinema Display as well. Or perhaps it is my graphics card (It's a Sapphire HD 7950 3 GB – the Cinema Display is connected with Mini DisplayPort). Or it might just be bad drivers for this card – they were never that good apparently.
Perhaps someone knows more than I do
All helps is appreciated…
Cheers!

No ideas?

Sorry, new thread on display buzz

I have a kind of different question about the display buzz that I think warrants a new thread. My MacBook Pro has it. Screen on full no buzz, screen off no buzz. Screen anywhere in between buzz. It really doesn't bother me. My question is, will it do the computer any harm. I.e. is this a sign that it is going to stop working at some point or is it just a pain in the butt that I'll deal with? Thanks in advance.

Michael,
I agree with erkthetech, however, please realize that none of us can speak for Apple on this or any other issue. As he mentions, I would call tech support, and while most of us cannot do without our notebooks for any length of time, I don't think I would wait on anything that seems to need repair.
My two cents....

Does your new 27" LED Cinema Display buzz?

Got my 27 inch LED Cinema Display yesterday: very nice monitor.
However, I have noticed a feint buzz/ticking coming from the bottom right of the monitor when the brightness is set high. Just loud enough to be VERY annoying!
Is this a feature of the monitor? Does anyone else's new 27" Display have a buzz?

yes, the reason it sounds like the electromagnetic interference that induces tones in speaker drivers (such as the microwave energy from cell phones) is because it is essentially the same mechanical action... which is a resonation electromagnetic coil (which will produce tones at whatever frequency it is vibrating).
The specific tones that it is producing are dependant on the electrical properties of the circuits attached to the coupled device - but it's probably possible that particular properties could cause the coils to create more than a single tone (just like a speaker)... on mine the tone didn't quite sound singular, but since the amplitude was analogue to the brightness i guessed that this pointed the transformer.
It used to be such a serious problem in inductively coupled conductive devices that it could shake the devices to pieces. These days it's only really an irritation in terms of noise - but it remains necessary to design the structure and housing of these devices to dampen and minimise these vibrations.
In much larger transformers the noise is very noticeable (have a listen the next time you pass an electrical substation).
... i could be wrong but it's a common problem in electronics and i think it's likely.

My display buzzes at any setting other than full brightness or off.

Im just trying to figure out what to do. Other than that, this macbook is absolutely flawless and has been a dream to use. It seems apparent to me that this is caused by a faulty display inverter. My question is, how much of a hassle is it to get this fixed, and can it be done in a local apple store? I would love to hear anyones experiences.

i think you should bring it in to your local apple store and let them check it out.. if they think your problem is serious enough they might even switch it for you..

MBP 15'' retina display making a constant buzzing noise

I purchased my first MBP about three months ago, I have been wanting one for years and FINALLY
saved up enough, I use it everyday and have never had a problem, until now..
There is a weird buzzing noise, it's super annoying and it's constant..
I just tipped it upwards to listen, and it started making a horrible scratching noise, along with the buzzing. (not doing that again)
However the buzzing is still constant, the only time it stops is when it is shut off completely.
I just want it to go away!!!!!
I'm absolutely heartbroken about this.
does anyone have any suggestions on what my next move should be?
It is sunday so all the mac stores will be closed by the time i am off work.
Should I stop using it? I don't want to make it worse.
HELP! PLEASE!

Won't turn on, flashing light, loud buzzing when I try to charge it?

My ipod died in April and I got a replacement from the apple store as it was still (just!) under warranty. I woke up in the middle of the night last night because my ipod was flashing - not on and off, just a blank flashing light. I tried turning it on and off but it didn't work and didn't even turn on.
When I got up today the flashing had stopped. I tried charging it but as soon as I plugged in the lead from my computer it started making a really loud buzzing noise. I don't mean the whirring/clicking noise that seems to be common enough when they die (that's what happened my last one, but it would turn on and display the battery with exclamation mark), but a real buzzing sound.
It started flashing again too after being plugged in for less than a minute. I left it plugged in for a while but the noise was driving me crazy so I've unplugged it now.
Has anyone come across this problem before? I haven't dropped it or had it near liquids etc, I've been treating it like a newborn baby since the last one died! I've googled and tried searching apple support but I haven't come across anything similar. Any help would be great, thanks!

If you connected it to both your computer's USB port and a USB power adapter on a wall outlet, I think you've ruled out a problem with the power source. Since you at least get the red light, the USB docking cable is probably OK.
So, if it's not the USB port or the docking cable, the cause is likely to be on the shuffle. It may be the battery or a problem on the logic board. If it was just the battery, I think it would still appear in iTunes on the computer (or at least be recognized by the system).
(If this shuffle is less than one year from purchase date, it is under warranty.)

MSI 970a-g46 motherboard starts up but doesn't display anything.

Hello, I'm having problems with a new motherboard I got from Amazon, specifically the 970a-g46. The following are my specs in use with this motherboard:
CPU: AMD Phenom 2 x4 965
GPU: nVidia GeForce 560 GTX
Ram: 8gb Kingston HyperX Fury 1866mhz.
PSU: Corsair 650TX (650 Watts)
Compatability-wise, everything checks out so I wasn't expecting problems at first. All the other parts excluding the ram I've used before. Here's exactly what happens:
I power up the computer after everything is installed and connected. The 4 phase LEDs turn on which tell me the CPU is powered up and working (so I assume). I don't get any beeps or buzzs mainly because I don't see any speaker/buzzer on this board. The monitor blinks and while it is connected to my GPU, it doesn't display anything, it's just a black screen. I can leave it on for a few minutes and I'll still not see anything happen. An important observation here is that my keyboard which has LEDs will turn on after a short period of time in boot-up (with my older set-up that is). This does not happen ever regardless of how long I leave my computer on on this new mobo.
I've gone over and checked/tested numerous things:
* The PCI-E and ATX cables for the GPU, motherboard and CPU are all connected and secured (I've tried both 4-pin and 8-pin connections for the CPU, neither help).
* I've tried jumping the CMOS multiple times to no avail.
* I tested the ram on another computer and it worked just fine on that one.
* I've tested the motherboard without a GPU and it still does nothing (though I think that's because this motherboard doesnt have its own integrated GPU for some reason).
So far the only possible reasons why my computer is not working is because of my PSU (very unlikely as it's only a year old and it's a Corsair, which I've heard is very reliable in the long-run), GPU (It is quite a few years old but even without the GPU my computer still doesn't go past boot-up), CPU (possible due to its age and how many freaking time I've reseated it (probably around 8 times) so I wouldn't doubt it, but before I put it into this motherboard I did check its pins and they were all there and placed nice and smoothly into the socket.) and finally the motherboard (it's possible that this is just a defected motherboard and giving me a super hard time which would be a first in all the years I"ve spent computer building).
The best case scenario of course is me giving some kind of oversight to how I transferred over the parts and connectors. I might've missed something obvious to please any advice/insight on how I can solve this problem would be greatly appreciated
EDIT: Some other things I did but forgot to mention:
* Checked ground nut things and ensured they matched the specifications of the motherboard ATX; only 6 are under the board and each one is aligned up with the holes on the board as designed.
* Tried booting up without powering the CPU. Only one phase LED light came on, still the same problem (for an obvious reason this time now).
* Re-seated GPU multiple times, re-connected cables multiple times.
What I have NOT done is re-seat the CPU because I am almost out of acetone so I would need to get another supply of that which won't be until tomorrow. I also have not re-seated everything back on my older motherboard to check if it still works. Tomorrow I'll most likely do that and if I find that the old motherboard works flawlessly then that tells me that the new motherboard I got is either defected or there's some compatability issue I"m missed out on.
EDIT 2: Just found a speaker and plugged it into the motherboard. Booted it up and I got no beeps whatsoever. So this mobo is giving me no video activity (there is a signal it's just blank), and no beeps from the motherboard. I have no idea what that could mean at this point.
EDIT 3: I decided to test a few things with the new speaker I just got. First I removed ram and tried running, I got 3 beeps which I assume is the beep sequence of faulty/no ram. Removed the power to CPU and the GPU itself individually, gave no beeps this time.

What's the serial number of your MB? Needed to determine what BIOS may be on the MB. Exactly which version of the CPU is it? There were several different 965 CPUs and they required different BIOS versions, 1.2, 1.9,2.2 depending on which CPU you actually have.
Also another problem may be that native memory supported by your CPU is DDR3-1333, not 1866
None of the supported CPUs have integrated graphics, any MB graphics would be in the chipset, not CPU. Examples would be 785G, 880G
Thank you very much rhradacut! The problem was that the mobo for whatever reason was forcing 1866mhz on my CPU when it only supported up to 1600mhz. I had to install a spare ddr3 module to downclock it so that I could access the BIOS and manually set the DRAM timing to 1600mhz for it to work. That's a very strange problem that I figured would've been auto-resolved by the hardware, and would also be a big problem if I didn't have any spare DDR3 ram to work with.
Once again thanks for helping out on solving my problem.

Crackling, Popping, Buzzing Noises in Audio

Recently (within the past week) my audio has started to crack, skip, pop, buzz, and all sorts of things. I have a Pavilion g6 1d08dx laptop with Windows 7 64-Bit, 4 GB RAM, and it's about 2 years old now, but I recently re-installed the OS, about 2 or 3 weeks ago after my old HDD failed.
I notice when I hit the wifi switch, the latency gets really bad to the point where it is just static-like buzzing and crackling, whether I'm turning it on or off. I've tried to reinstall the driver (IDT High Definition Audio), and updating it, but so far nothing. If it helps, there's two other audio drivers under that section- Intel Display Audio and Bluetooth Hands-Free audio.
Perhaps an update to different drivers is available. What free software could I get to check this?
Thank you.

Can anyone help?

I have my Macbook Air hooked up to a Tunderbolt Display, is there any way to either power on or wake from sleep mode using an Apple USB keyboard pluged into the Thunderbolt display?

I have my Macbook Air hooked up to a Thunderbolt Display, is there any way to power on the Macbook Air using an Apple USB keyboard plugged into the Thunderbolt display? I would like to be able to keep the Macbook Air in the Archbook dock and not have to open it to power it on?
Thanks for any advise.
