MacBook Pro :: Static Noise When Connecting To TV?
Jul 29, 2009
I connected my MacBook Pro to my TV (non-HD) using a 3.5 to L/R composite for audio (from headset hole) and an Apple DVI to S-Video/composite for video. I'm using the S-video part of the adapter. I get good sound out of both channels, but when I connect the S-video cable, I immediately get static feedback from the stereo speakers (the L/R composites are connected directly into my stereo receiver and the S-video goes into my TV).
The video quality is fine when it's connected...

This has been driving me nuts for a few months now. My macbook keeps emitting a sound very much like static. Only today, I realized that this sound goes away when the processor is working. So if I scroll down in Safari, open a New Folder, etc, the sound briefly pauses before resuming again. Almost sounds like a refrigerator. It bugs me a lot lot. Anybody else having this issue? Or has Apple been able to fix this for anyone?

I have a Macbook Pro MC666ll/a. It is a core i7 15" with the AG screen. The issue I am experiencing is a random static noise coming from my speakers every now and then. If i have external speakers plugged in then the sound comes from the external speakers. Is this normal?

There is a loud and really annoying humming & static noise when I connect my charger to my MBP. The humming only comes out of the headphones jack, and not the MBP speakers. This really cripples me in my work as I am a music producer.
Mp3 of the noise: [URL] ....

I bought this in hopes of connecting my Macbook to my tv: [URL]
So I connected it, but all I get is a very static-y image... no matter what resolution it is, it still has static/distortion.

My brand new MBP 13" (Mid 2009) makes a high pitched whiny sound that appears to come from the upper left corner ( where the MagSafe connector is). It is not caused by the display because even when I turn it off (the display) the sound is still there. It goes away when I turn off the computer, tougth. Also it's not caused by the MagSafe because when I disconnect it the noise doesn't stop. I have used gogle and the forum search and found people with the same problem. Those people could fix it by starting photobooth. Same works for me. So I guess it's the processor. What I want to know is: is this normal? Because most of the other people who I found who have this problem had a 2006 MBP not a 2009 like me.

My Powerbook has been making a static-y sound from the back of it at random times. It sometimes won't do it all day, and then it will randomly start, and won't go away for a while. It's actually doing it right now! I've tried putting it to sleep for a few minutes, but it started back up again when i woke it up. There, it just stopped again! It can last from a few minutes to an hour, completely randomly! This problem started when I had Apple replace the logic board on the Powerbook a few months back, and numerous repairs later, nothing has changed, so I'm hoping someone here has an easy fix!

My mac has worked great for the last 2 years since ive owned it and it just started to act a lil differently about 2 weeks ago. I started to notice that it started to act a lil slower than normal when i was surfing the internet. Then a couple of days ago the computer started making like a buzzing noise , kinda sounds like interference . Like when a cell phone gets close to a stereo system. Sometimes the noise will go away and then when i start opening diff app. that use computer cpu the noise happens again. It was just making the noise and i was dealing with it until the computer started to crash. It would look like the screen was on fire and everything would just freeze. Do you guys think it is the hardrive ?????? and if it was what would be my best option for fixing this. Can i save the stuff that is on my current drive ?? I have a bunch of stuff that is very important on this hardrive.
whats the best place to buy a hardrive if i need one ? and can i buy a hardrive that can hold more than the stock 74.53 toshiba MK8025GAS ?

Very occasionally the screen on my iMac (early 08 24") goes blank and it makes an incredibly loud static sound that's independent of the volume control setting. The power then needs disconnecting to restart the machine. Haven't been able to tie it to any specific program. Apple Care asked I leave it on logged in on a new user account (at the time I originally thought it only happened in sleep mode, but have since discovered this is not the case).
It's happened maybe 3 or 4 times in the same number of months. I've only found one similar case on the net, with someone suggesting it was Safari 4 beta, which I've found not to be the case with mine. It's on extended warranty. I think there's something seriously wrong with it (it's already had the hard drive and power supply replaced).

I just got my 2.0ghz Alu Macbook a few days ago and everything works perfectly well, the thing is that after day one the magsafe started to emit a low pitched electrical whistling noise. It tends to be there a few minutes after booting into the OS and then it turns down to almost unhearable, but I experienced it returning after a few hours of use and then disappearing again. If I move close to the escape key I can hear a crackling noise emitting from the magsafe.I'm not trying to be overly nitpicky or anything but I read somewhere that if it's doing that it would be a faulty Mag-Safe board or something.
Does any one you guys know anything about this? I have the 14 days to return it as I bought it online from the Apple Store so if it's a faulty part that might die/break/ cause problems later I might have to.

Sometimes I lift and carefully move my 17-inch MBP a short distance to another flat surface without putting it to sleep mode, it starts making really loud mechanical noise when I put it down, so loud that people in the same room can hear the noise and I can feel vibrations too! What causes this? Where does this noise come from? Is my MBP defective?

My first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?

On my 13" MacBook Pro, the hinge makes a cracking noise on the right side of the computer (near the power button) when the screen is positioned all the way back.The entire hinge also makes a loud popping noise when I adjust the screen position. The screen seems very tight, and it takes a little bit of effort to move the screen, and when the screen is moved it makes the loud popping noise.
This is probably going to make some of you guys cringe, but sometimes putting pressure down on the top of the case close to where the black hinge meets to unibody enclosure seems to stop the popping noises. Putting downwards pressure on the hinge, or flipping the computer over and putting pressure on it that way, also seems to alter how much popping noise there is.
If I mess around a bit with applying pressure on different parts of the computer around the hinge, I can usually eliminate the noise. But, the cracking noise when I put the screen all the way back is still there.Any ideas what to do? It's not interfering with the operation of the computer, it's just incredibly annoying and this is only a four month old machine which shouldn't be creaking and cracking already.

Has anyone else had problems with an old G3 Pismo making an annoying squealing noise when plugged into a charger? There's a lot of noises mentioned in mac/apple forums but none of them relate to this one. Here's what it is not:
It's not coming from the screen or the fan or the speakers (it's under the keyboard). It's not low or slightly annoying (it is a loud squeal). It happens only when the power adaptor is plugged into the laptop.(it used to cease after I unplugged the power adaptor and plugged it back in three times; now that solution doesn't stop the noise anymore). It charges ok, and runs ok, scream or no-scream. It's quiet right now, but if I move the adaptor to another plug it will start again.
I was going to live with this, but today after an hour of operating quietly it just started again, and I hate to leave the house with this going.(it will scream whether the laptop is on or off. I have a really old battery and cannot replace it (I am currently staying in Mexico for the summer). Battery life is 45 min. I haven't tried pulling the battery out. That would be too easy.
This all started when I bought a replacement power adaptor (generic),after the original one melted down, but I could stop the screaming by unplugging/plugging it in again once or twice. Then I bought an expensive iGo adaptor, and it does the same thing.
I Did the PRAM and PMU reset.I can hear it over music or the tv. It grew lower in pitch today after squealing for a half hour. I'd normally not let it go on that long, but i was
in the other room.Is my PISMO dying?
(400 mhz pismo G3 500 sdram, osx-10.39, no os-9 or Classic, new 80g HD)

I just got my macbook pro yesterday and ran it all yesterday not hearing anything. Today when I woke it from sleep I could clearly hear the fan or hard drive going. I was in a quiet room and it's quite annoying.
istat says its at 2000 rpm so thats when I started thinking it may be the hard disk. It does pulse every now and then but thats even while it's just sitting idle.
I guess I could live with it but its just annoying. Anyone else having this?

I recently purchased the latest iteration of the MBP 2.2 ghz. When plugged into a wall socket (220v here in HK), if I touch the lid I can feel a light electrical current in my hand - similar to the feeling of electric massagers, a light vibrating feeling. I didn't notice this while plugged in in the States (though I bought the comp here in HK). It doesn't hurt, but is this normal, or something I should be concerned about?

I'm trying to connect my Macbook to my work internet via an ethernet connection- I do not have access to the main router, just a ethernet jack. Currently, I have a desktop PC at work that works fine and when I plug in my Macbook, the machine does not recognize the internet. I spoke with my IT department who said that I need a static IP address but they do not support Apple so I'm on my own. I tried typing ipconfig in the command window and got 3 numbers : IP address, subnet mask and gatewy address. In the system prefs I typed in the IP number, subnet mask but am not sure where to put the gateway address - Still can't connect to internet -

I just walked in the door and shook my mouse to wake up the screen. My Macbook Pro's display came up instantly (and normally) but the second monitor... a SyncMaster 220WM hooked up via mini displayport to DVI, showed nothing but snow... like exactly what you'd see if a TV station wasn't getting reception.
I'm running on the 9600m GT at the moment. 2.66Ghz C2D mid-2009 MBP unibody.
I waited about two minutes... and the image of my second desktop came back to normal in an instant. No excessive fan or heat... no need to restart, no kernel panic... nothing of that sort. And the kind of static that showed up again reminded me of either a TV channel with no reception... or the static you see when you boot into a PS3 game via HDMI... you get a momentary bit of static when it negotiates the HDCP signal.
I never encountered this issue using the same cable connected to my SR MBP with DVI.
Is this a graphics card issue? or an issue with the mini-displayport DVI adapter? Was it having a hard time negotiating HDCP?

Twice this week I?ve been shocked by Static electricity as I touch my MacBook Pro. It?s cold so I get shocked a lot lately. Is the MacBook Pros internal circuits safe from static shock? Is the outer shell protecting the CPU?

So I'm at a client tooling around with my late 2008 Aluminum MacBook. Carpet. Cold, dry weather. Are you getting scared yet? Go to pick it up off a table and zt! Shocked the hell outa myself and apparently my MacBook. I grabbed it on the right hand side and the static charge must have discharged through the slot loading cd rom drive. Now it won't charge. Battery and Mag Safe brick tested fine at the Apple store. They're going to swap out the Mag Safe port for $110 first and then the flat rate repair for around $380 if needed. Note to all Aluminum MacBook/Pro owners. Ground yourself, or plug in the grounded PSU brick.

17" i7 500GB 7200rpm MBP machine a few days ago... it's great.
However, my internal mic is having some major problems. The sound quality from it is just awful.
It sounds like it is barely picking up my voice and it is just getting static and other strange sounds.?
Do you think I should contact Apple?

Last week my macbook froze and when I force restart the screen started up like the picture attached, It started normally one time but then froze and it's been like this for about five days, what could be the cause of this? Could it be a virus/software or is it a hardware issue? All my systems and stuff ar up to date as well.
Also, another issue I've been having with my iphone I couldn't sync any music to the device and I couldn't delete any of the songs from my phone via my mac could that have something to do with it?

I've had a late 2010 Macbook Air for over 3 years (February 2011). About a week or two ago I started hearing a strange popping noise every now and then while I was using headphones. I thought it was a problem with the headphones but then discovered the same thing when I used different external speakers. Almost simultaneously the internal speakers started periodically having no sound at all, even though it wasn't on mute. This was previously fixed by restarting the computer, but now the problem is permanent. The popping noise when using headphones has also rapidly worsened, and now crackles constantly and sometimes there is even very loud white noise. This occurs with any program on my computer - web browsers, spotify, itunes etc. I'm using Mavericks but the problem started some time after I installed it. After doing some googling to try to fix it I've tried:
- Turning it off and on again
- Installing AntiPop
- PRAM reset
- SMC reset
- Disabling and reinstalling Adobe on google chrome
- Resetting the sound card with terminal
Info:
MacBook Air, OS X Mavericks (10.9.4)

Just got my 15 LED SR Macbook Pro. When I plug my bose speakers in at my desk and listen to itunes, I am getting a static pop sound. Should I take it back or is it fixable? By the way, LG panel and no yellow 1/3 of screen. Initially thought it was yellow, but I calibrated it, and now it only looks yellow if viewed from the side. Head on, white. One thing I have noticed, when I watch movies on it in the dark with the brightness turned down (cause this thing is a torch), I am getting quick flashes when a screen has high contrast light and dark. I am very sensative to LCD flat panel TVs that use a colorwheel. Like a JVC dilila, I see rainbows! Is that normal for an led flat panel to see "quick white flashes of light"?

I just got one of the new aluminum Macbooks and everything works great... except when I plugged in some headphones. Whenever audio of any sort starts I get an almost silent static like noise in the background... be it sound from a Youtube video, Ventrillo, iTunes... anything. After a couple minutes the static goes away. But if any sound occurs the static returns. Most of the time you can't notice it because the audio that is playing is louder. But when its silent you can hear the quiet static like noise. I have some Sony In-Ear Earbuds. I tried plugging in the gross default iPod earbuds and I couldn't hear the static with those but that may of just been because I can't fit the damn things in my ears. I don't know if its my Macbook or the headphones just don't like the Macbook.

I have a less than 1 month old White MB. I have become aware of an electronic noise emanating from below the upper left portion of the keyboard, under the q,w,e keys. The noise can be best described as a mechanical mosquito; it is a constant high-pitched buzz that starts once the computer has fully booted up, and doesn't stop until it has been shut down. Although it is quiet, if you get your head anywhere near the keyboard it is readily apparent and obnoxious. It does NOT appear to be fan related, as I can hear those going as well. I have listened to other Mac laptops with equal scrutiny, and this noise is not present.
A simple Google or Apple forum search indicates that people have been noticing this problem for years. Indeed Apple appears to have acknowledged it recently with MB Pros: (URL) I believe it indicates a faulty logic board.
- Have others noticed this with their MBs or MBPs?
- Does anyone know the true source?
- Most importantly can anyone give me some tips with how to deal with Apple on this?
They have suggested I go talk to the store I bought it from. Those guys claim not to hear it (a common theme from what I have read). However, this is highly dependent on the level of ambient noise and hearing ability of the individual. I already had to return one MB that was DOA, and now I have this one. Given the expense of this purchase and the age of the machine I feel that I am entitled to a new one that does not display these issues. How can I effectively communicate this to Apple or my retailer, neither of which will likely want to comply?
