G500 5.1 Surround. Buzzing noise from the sub/amp?

Hello everyone, new here =) First off, I am suprised at how many things have gone wrong with the G500 after searching around on the forums.
I have the G500 + while listening to music (low volume/bass) I start to hear what sounds like someone clicked on a mic and then just a buzzing noise. Thinking it was two wires touching I disconnected the speakers and checked them.
Everything seems fine, I plug everything back in and the buzzing does not stop. I start smelling an electrical burn and I'm unsure if it's the subwoofer or the amplifier going bad. I'm banking on the amp at this point.
Anyone have similar problems and might be able to hint me in the right direction? I'm going to be taking it apart later to see if anything stands out on the board.
Thanks guys

I appreciate the reply. I did view that thread but I didn't feel it was related to my problem. I don't think it's a blown fuse problem as they still work, but I'm more than sure it will stop working if I keep trying to use them.
If you think I should just post there because of the knowledgeable people, I'll do so. Thanks a bunch!

HP 2509m 25" emitting a strange fuzzy buzzing noise from the back

Hi, i've had this monitor for just over a year now, so far everything has been great, no complaints at all. Untill recently, the monitor makes a weird buzzing, fuzzy sound from the back. I dont use the oboard speakers as my main audio, i have after market speakers. When i power off the monitor the sound goes away. Does anyone know how to fix this problem ? Do i have to take it in to a repair shop ?

Did you bother to read my post above and click on the LINK in it???
QUOTE... "Please review the many posts concerning the HP 2509m monitor on this forum. The buzzing and/or any flickerin of the screen appears to be related to the backlight inverter circuits and/or the backlight CCFLs."

When my computer is playing sound, it makes a loud buzzing noise and the computer locks up

When my laptop Pavilion dv6 less than a year old, computer is playing sound, it makes a very loud buzzing noise and the whole computer locks up. I hit the lock symbol and then swipe my finger again to get out of the website (youtube) or close out the program playing sound or it will do it again.

Hi,
Shut down the notebook. Tap away at f10 as you start the notebook to enter the bios menu. Under the Advanced or Diagnostic tab you should find the facility to run tests on both the Hard Drive and Memory. Post back with the details of any error messages.
If both the above tests pass, try the following.
From the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'. In to the prompt type the following command and hit enter.
sfc /scannow ( note that there is a space between sfc and the / )
Let the process complete, then type exit and hit enter.
Next, click the Start Menu, click Computer, left click Local Disc C once to highlight it, right click Local Disc C and select Properties. Click the Tools tab and then click the button to 'Check the Drive for Errors'. In the following window make sure both boxes are ticked and then click Start. Part of this process will require a restart to check the drive.

Is normal at power mac make noise from the optical drive?

when I power , the mac make some noise from the optical drive , I guess, This is normally? this noise just appear when I update my Mac to Mountain Lion 10.8.2
Thank you everyone!

Normal, normal, normal. Don't know the reasoning behind it - I suppose the MBP is trying to load anything that might be in the drive at startup. Had me confused for awhile, way back when...

Crunching noise from the optical drive

Whenever I try to insert a CD into the disk drive, I get the noise from sample-1 under the "Inserting a disk" section from the Apple support link Mac notebooks with optical drives: Noises from the optical drive - Apple Support
I can't find anything on how to fix this yet so I'm hoping somebody here can help. I bought this macbook secondhand off of somebody on craigslist almost a year ago so I have no way to contact them anymore. I've only used this computer as a backup so I've never known this problem existed before now.
Any thoughts?
Edit: The CDs won't play and ejects after about 30 seconds of making that crunching noise without showing up anywhere on my drives.

If your optical drive is making a crunching noise it's probably a goner. You can replace it yourself using the guides at iFixIt https://www.ifixit.com/Device/Mac
Or better yet replace it with and SSD for lightning fast performance and get a USB external optical drive.

The strap of my bag broke when my laptop was in it, now it is making a buzzing noise all the time and sometimes get a bit warm. I have warranty with protection plan, how do I fix it?

The strap of my bag broke when my laptop was in it, now it is making a buzzing noise all the time when I am using it. I have warranty with protection plan, how do I fix it?

Take it in and have it assessed. They do not have to know about the bag incident unless the explicitly ask for the specific details (like when you are being questioned by a TSA screener, LEO, etc.). As far as you know, the noise started up and it is getting warm. With luck it is just an unbalanced fan that needs replacement.

Background noise removal takes about 3 seconds into each clip in timeline to kick in, so each clip has noise in the first few seconds. How do you get this to remove noise from the very start of the clip?

Equium A100-147 - Clicking noises from the HDD

For a while I have had clicking noises from the HDD and when the laptop failed I assumed the drive had packed up but when trying a replacement nothing happens. I get a blue light for battery and a (faint) blue light for DC supply but nothing for power or disk. However, when I connected an external drive yesterday it booted fine and when I disconnected it the laptop continued working from the internal drive. But again this morning it is dead and cannot boot. I have read that the BIOS can stop recognising the drive or maybe the settings are not being saved when it is turned off. Could it be the motherboard battery ?

If I understand you right your notebook is death now, right?
I really don't know what to do. Remove the battery and HDD and try to start notebook. if the same happen again it is time for new notebook.
I don't think repair is best option because it can be pretty expensive. Satellite A100 is pretty old notebook and you can sell it on eBay. Someone will need it for replacement parts.
Maybe my opinion sounds stupid but I don't know if you have time to search for new parts. I cannot say for sure but there must be some serious problem when you cannot even enter BIOS settings or see anything on the screen.

Strange noise from the back of my iPad

Hi!
I've had my iPad 4 since Christmas and its always made a strange noise from the back when releasing pressure. This happens when holding the iPad in landscape mode with home button to the right and since that's my favorite way to hold it it happens all the time.
Apple support could not verify over the phone if this was normal or not, should I take it to them for a look? I suspect something not being properly glued inside but I don't have a clue if its serious or not. Is it worth opening up and having it fixed?

Hi King Penguin.
Many thanks for your quick response
I've swapped sockets and it still happens and I've tried the plug from my I phone as well and no change. I've spent the last hour or so searching the forums and come across so many conflicting theory's included responses from apple where people have been told its normal, the general consensus seems that it's an earthing problem with the supplied adapters, i.e no earth connection in the supplied adapter. I'm no electrician however but seems strange to me that apple know of this and are quite happy to to nothing about it. I'm going back to the apple store this week to discuss it with them and see what they say.

Try an SMC Reset. (System Management Controller)
Shutdown>unplug from power for ten minutes>press and hold in the power button for ten seconds>startup again.
Also try a PRAM Reset. (Parameter RAM)
Shutdown. At the bootup chime, hold down CMD-Option-P-R together, wait for two more chimes, total three, then let go of all keys to finish booting,
If this doesn't do it, run the Hardware Test in Extended

Digital Audio Noise from the Headphone Jack

I have been searching for a while to see if anyone else has this problem.
I have random faint digital noise (bleeps, bloops, and whirls) from my headphone jack. This happens regardless of application. I can get it going good by just tossing the volume bar back and forth on the sound pref panel.
I have considerably less of this from the line out but still detectable noise.
I have disconnected everything non essential from the Mac Pro and my power outlet are reduced to a minimum. (monitor and Mac)
I have tried numerous headphones including Etymotic ER•6 and Sony MDR-7505.
This has always been present in 10.4.7 and 10.4.8. Like I said, its faint in volume - but it gets annoying!
I have read the following below and believe these do not apply to me because this is not an external powered device.

I found out today what is causing the noise on my Mac Pro!
Our next door neighbor has a really high power HAM radio that I am picking up static and transmissions from. I thought I was going insane when I heard weird voices coming out via my headphones. I know it is our neighbor because I heard him relay his name and location. Had to get my wife to listen to prove I was not going crazy.
Here is the weird thing. I do not have AirPort or BlueTooth on the MacPro...so I cannot figure out how the transmission is permeating the Mac. Could it be a shielding issue on some internal component?
Thanks!

Buzzing Noise from (IMAC 27-INCH,MID 2010)

I have noticed this buzzing noise (like crackling electricity of sorts) comign from the left side of the machine out of the cooling vent. I bought my IMAC in 2010 and have not had any problems with it until now. I noticed the "noise" a couple of months back and it would show up here and there every once in a while, it was not annoying, so I let it be. Until this last time, when the noise was loud and annoying, I could not just forget about it. I am under warranty and called into Apple to see what can be done for this problem. I was told to take it into my nearest Apple store to get it looked at, since over the phone they could not do anything about it.
I took it in May 11tt, 2012 and the guys at the Genius Bar were stumped? They had no clue and it was the first time the two gentelmen that helped me heard of this kind of problem! Since there is no moving parts on that side of the computer they escalated the problem "query" to apple engineering and was told it would take a week for a response. Thus far, I have not been updated on my problem or contacted as to the status of my problem. Its been 12 days and will be contacting them to see whats up!
Will update if problem is resolved!
Has anyone had this type of problem?? Any advice would be apprciated!! Thank you

This might seem a strange answer, but it has fixed this fault on my 27" two year old iMac (at least for a few days now, will be monitoring).
I had this very fault suddenly develop last week.   It was consistent, the noise increased with screen brightness, but was also present with the screen asleep.
I looked at every forum on the subject, became almost convinced my fans weren't controlling properly as well.
I decided it was the switched mode power supply, discussed repair options with my local Apple Store.
Checked the household mains voltage - I'm in the UK, it was slightly low at 236v AC, but thats acceptable.
Then ....
We have a garden full of water features and LED lighting.
I just decided to check all our power junction boxes that supply power to various pumps and lighting.
I found one of the boxes full of water, with the Live, Neutral and Earth, and the 12v DC cables all under water and shorted together.   The terminals were all corroded and burnt.
Yet, I had no faults present in the garden, everything was running normally.   And the RCD breaker had not tripped.
I repaired the box, fitted new terminals and rewired the box.
And since I did that, my Mac has cured itself.
I've had it running for hours to get hot, no noise, gone completely.
And the mains voltage now measures 242v AC (should be a nominal 240).
The RCD did not trip because, with all the cables shorted in water, there would no out of balance condition to initiate a trip.
So, I can only assume that arcing or the short was causing some harmonics on our mains supply that was been picked up by the coils in the Mac power supply.
The 12v DC supply in the junction box was also supplied by a switched mode supply.   I dont understand why something didnt blow in the garden, but it didnt.
I'm monitoring the Mac as the solution just seems unrelated.
Oh, and I noticed our Intruder Alarm panel was humming loudly and now it isn't.
So, I would suggest anyone with this issue takes note of any unusual humming or buzzing in any other electrical item within the house, or outside.   It may indicate you have an issue elsewhere.
Even any loose mains plugs in equiment could be causing a slight arcing on the contacts, causing noise on the mains that may be getting picked up.
Coming from an interest in high-end analogue Hi-Fi, amplifiers always performed better with a dedicated, clean, mains supply, usually from a 40 amp rated cable fed direct from your electricity meter to supply your Hi-Fi.
The amplifiers would exhibit less noise and a cleaner sound with more detail.   And the transformers in the power supply were a lot quieter too.
And what do we have today - ethernet tranducers plugged into household sockets, superimposing high frequency signals onto the household wiring.
They would cause havoc with top-end amplifiers, I'm sure.
I hope this is the solution, saves me an expensive repair.
I've never had any problems with the six Macs I've owned in the last 12 years.

Clicking noise from the screen moving

My Phone is making a clicking noise on the right hand side of the screen, the movement of the screen cannot be seen but it can easily be felt. ive seen this as a problem before from other questions and how most cases have been sorted, however my phone has scratch marks on it, not from being dropped, just from a set of keys in my pocket! :/ will my phone still be covered by warranty to be replaced?

No one here can speak for Apple about what they will do. They'll examine it and make a decision nor do we have any idea what they will think.

When i play a video or movie i get a buzzing sound from the speakers. how do i solve this problem?

I get this buzzing sound from my speakers when I play a video, or movie either from the internet or playing a DVD. What can I do to solve this problem

A: There is no such thing as an unlocked iPhone 3Gs in the United States. ALL iPhone 3Gs's sold in the US are locked to AT&T. AT&T will NOT unlock iPhones, therefore it is not legitimately unlocked.
B: Sprint is a CDMA network as others have mentioned. They do NOT use SIM cards. The iPhone 3Gs will NEVER work on Sprint. Ever. It's not physically possible.

How to eliminate the noise from the stepper motor

I’m using stepper motors to move a traverse on which a hot-wire anemometer probe is mounted. When the stepper motors are turned on, they induce noise on the analog signal of the hotwire anemometer, or of any other transducer, at multiples of 120Hz.
The stepper drives are P41 Series made by American Precision Inc. The P41 Series contains a power supply, a motor drive and a logic controller. The logic controller inputs are optically isolated and utilize the 5 VDC supplied internally by the drive.
An NI 6251 or NI 6024E DAQ card is used with LabVIEW to send digital output signal to the logic controller in order to step the motors.
The AI input channels of either NI 6251 or NI 6024E DAQ cards and LabVIEW are used to acquire the signal of the hot-wire anemometer. Different DAQ cards are used for the data acquisition and the stepper motor control and the noise is transferred through the laptop to the data acquisition card (analog signal).
All cables are shielded and the noise was confirmed to be conductive and not radiative.
There was no difference when measuring the analog signal with Differential or RSE.
As a test, the leads from to the drive’s logic controller were connected to the AI input channels in order to check the magnitude and frequency of the noise flowing to the DAQ card and were found to be 5 V peak-to-peak at 60 Hz.
Please let me know if you have an idea on how to eliminate this noise.

It sounds like you have a ground loop issue. If possible, try totally isolating the stepper controller from the data acquistion AI more than you already have. This could include any of the following:
Ensure the optoisolation on the control lines fully separates the power and ground of the digital output and stepper input.
Use different grounds for the stepper power supply and the DAQ power supply/computer. Isolation transformers can help here.
Use lower inductance lines for the stepper controller. This will reduce the movement of the ground.
I suspect you have probably been over the above, so you are left with filtering the noise out of the signal. Since it has high harmonic content, a simple low-pass is unlikely to work well. Your best bet is probably to characterize it and use some sort of Fourier filtering. If the relative sizes of the harmonics are always the same, you can take the Fourier transform, find the height of the fundamental, use this to calculate the sizes of the harmonics, delete them from the Fourier transform, and do an inverse Fourier transform to recover your signal. Alternately, you can use a series of narrowband filters to remove the noise, although this will also remove any signal at the same frequencies. It is better if you can improve your circuitry to remove the noise.
Good luck. Let us know if we can help you more.
