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."

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.

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!

I recently migrated my MacBook from 10.5.8 to 10.6.8, using the Snow Leopard CD I purchased from Apple. Since then I have noticed a strange ozone smell coming from the MacBook in the area where the hinges are to open and close the unit. I was told by Apple that it probably is not serious and is coming from the fans in the MacBook. It is true that the smell/odor is more intense when the fans are working. Apple said I should take the MacBook to an Apple Store to have the hardware checked out. Everything seems to be working correctly. I am backing up automatically wirelessly to a Time Capsule, which I had not done until recently, although I had purchased the Time Capsule in 2009. I have not noticed this odor before. Does anyone suspect something more serious that may be going on?

You may be smelling it because with the new OS the processor is having to work harder causing it to get hotter then it would with the other OS. I can't say there is nothing wrong, but what could be happening is just that, it's getting hotter so the fan is spinning faster and moving more air so you are getting more of the smell then you would before. I would still continue to back it up, and take it to the Apple Store at a Genius Bar and have them look at it to make sure. Was the computer ever in a smoky environment??

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.

My iMac makes strange clicking noises on the back of it

It makes some random clicking noises on the back of my iMac that just irritates me alot. What is wrong with it? I purchased it like 2 months ago and I don't think it's a virus or anything. Can anyone help?
Thank you

Hello:
I suggest you take the computer in for diagnosis. Strange noises are not normal.
Incidentally, there are NO viruses that affect a Mac running OS X - NONE.

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.
Regards,

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.

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.
Either your Uncle misunderstood or he was mislead. Send it back and tell him to get his money back. Buy an iPhone in India from a supported carrier.

Verizon Westel 327W abroad - Buzzing sound from the Power Adapter ?

So I moved to Caribbean Islands for schooling and the DSL Modem from local company here was plain 1 port one. The voltage here is 220V, so I have put a transformer and then plugged my Westel 327W into 110V and it works great.
However, I am noticing a buzzing sound from within the power adapter. The adapter is running somewhat hot since I plugged it in a few days ago. Should I be concerned about this buzzing sound or is it just that its sitting on my desktop and I am noticing it now ? Its loud enough to be heard in a completely quite small room....
Thanks

Hi D_U, sorry to hear of your issue, sounds electrical and thereby out of my scope of support.

Mac Pro 2010 and Lion: buzzing noise from CPU board when idle

Hi all,
I have a 2010 Mac Pro with the 3.2 GHz quad core. I recently installed Lion and now whenever the CPU load falls below a certain threshold (approx. 10-20%) something on the CPU board starts to make a buzzing noise. It sounds like a capacitor or coil. Sometimes it is nearly impossible to hear but most of the time it is quite annoying.
Removing the CPU board and putting it back in, solved it yesterday. But after waking up the system this morning, the buzz was back again.
Also, this does not happen when running Snow Leopard or Windows in Bootcamp.
Does anyone experience the same issue?
Best,
b.lam

Then I would do a clean Lion install. Hopefully you saved the installer DMG.

Horrible buzzing and clicking noise from the fan - DV6 3046eo

Hello!
Two weeks ago the fan on my DV6 3046eo laptop began to make almost continueosly buzzing and clicking noise. My laptop is less than an year old (bought in December 2010) and such noise has never occurred before. I have done some "research" to find the reason, but without luck. I have read on Internet that the fan may be broken or loose. I am just using the web and listening the music. I have to admit I played some demanding games on the computer, like BBC2 and Dirt3. But the problem occured later. I can't imagine what will happen if I play games on my laptop now...
The fan seems to cool down the laptop, but it is like something is hitting it every third second or soand preventing it from running silently. The noise is strange and irritating because the frequency changes rapidly. Sometimes when I move the laptop or hit it a bit gently, the loud noise suddenly disappears and the normal continueosly noise takes over (I am ok with the latter one, though). After some while it appears again. The noise come and go. Reboot doesn't help much. I have also used an airspray can, but to no avail. I am thinking about getting the fan replaced by HP before the 1 year warranty runs out. I am not too comfortable to do so myself. What's the reason for this noise and what should I do?
Thanks in advance!
Sandip

Still no comments?
I am getting sick of this noise. I can't bring my laptop to school because it makes too much noise. Please help me.

Move! Buzzing noise from left speaker on T60/T60p

I've had this annoying buzzing on my left speaker on my T60p and another T60. It doesn't happen all the time - but when it does, it happens even when I plug in headphones.
I've called the support line, and they've replaced my speakers - same problem. I haven't had time to call back...
Anyone else having this problem?

Could be interference, my smartphone causes my PC speakers to emit gibberish every once in a while if it's too close. Most speakers aren't shielded against that.
