I'll cover the background to when this started happening.
I took my macbook out of an outer case to clean the shell itself.
I used wet ones which have alcohol so I wasn't worried, but also wasn't careless.
I once got a screen that said I needed to restart my computer. So I did.
everytime when i turn on my macbook, the top part of the screen flickers.. I don't recall seeing that happen when i first got my macbook. anyone else have the same issue? something i should worry?

Tried to reboot with OSX disc holding c. I'm lucky I got my disk out?
So my girlfriend boss wanted me to fix her computer. So I brought it home turned it on, and it didnt chime but it booted to the gray screen with apple logo/ slashed circle/and folder with a "?" So I made a USB Mac OS x bootable drive (FLASH) held down alt (try using a windows keyboard its fun) was able to select option and install a fresh copy. all seemed well was running really hot so I poped of the screen. HOLY MOLY! this thing is CAKED with dust, and I am not kidding it has literally piles of dust. So I ran updates, and did firmware updates. Turned it off for the night. Â
The next morning I went to radio shack and got Dust remove spray, opened it up made sure I was carful taking off the screen, and blew the sucker out. now its NICE and CLEAN. then i made sure I plugged everything in and turned it on. Drive spun like normal, Optical checked for a CD, and fans are also running normally. but no chime, no nothing stays as silent as normal but doesnt budge, it is like it hangs. Â

I am trying to repair a macbook pro for a friend, I think it's the logic board, but I wanted to check with you all before I go buy one. When the battery is fully charged, I press the power button, I hear the hard drive spin for about 5 seconds then stop. The superdrive on it is broken so I can't try the restore disk. I ordered Pram, I am going to replace that. I tried two different hard drives and I know they are both good, I tried them in the macbook and through a usb port, and the same thing happened both times.

I have a Powerbook G4 17 that I have been working on. I recently replaced the screen and verified that it worked prior to buttoning it back up. When buttoning the powerbook back up, I nicked two wires with screws. One was part of the LCD wire that comes from the LCD itself. The second was the airport wire that is wrapped around the screen. I wrapped them back up with a cover and preceeded to get using my comp again. Once finally put back together, I could not get it to turn on.
View 1 Replies View RelatedWhenever I move my macbook on my desk with the lid open, or when I open the lid, or when I close the lid, my screen flickers to black and then back open many times. Is this a weak connection some where? Sometimes the screen will stay black until I move the lid a little bit. I bought it refurbished from Apple this spring. I do not have applecare.
View 2 Replies View RelatedI bought a 22 inch monitor. its a pretty generic brand, but its very high resolution and works great on other computers. i got the vga adapter for my aluminum macbook (i posted in this section because its closer to the 13" mbp). i have an apple keyboard connected to it. i try to use it in clamshell mode and when i press a button on the keyboard to wake it up the screen just flickers as if its trying to adjust the resolution. strangely enough, it works perfect in mirror mode. anyone have an idea?

I'm using the MiniDisplay port to HDMI on my MacBook Pro and connecting it to my 720P Dynex HDTV.
All my MacBook Pro does is flicker 3 times for about 8 seconds that it goes back to normal.
She has a 2008 Aluminum MacBook, the standard 2.0Ghz model. Occasionally when she moves the screen or tries to angle it, it flickers. This doesn't happen every time.
I honestly haven't tinkered with any Mac laptops once the unibodies came out, so I am hoping someone can shed some light, give some advice, and maybe throw out some ideas for repairs.
Recently my Macbook Pro 2008 is having following problem. First there are wavy blurry lines appears on screen and then it freezes for a while and then it restarts its own. On restarts it gives following message.

I am looking at purchasing an Ibook G4 but the description of the item includes this:"When you switch it on it begins to load up i.e. the blue screen with the Apple logo, but then the screen goes black or flickers. Said friend has kindly wiped the hard drive for me so now when you switch it on it makes the �opening� noise then you get a blue screen with alternating �?� and the Finder logo."
I have a feeling this may have been a temporary fault with the screen connector being loose and possibly damaged.But i assume the alternating "?" and the "finder logo" is simply a lack of OS?
I just got a new MBP i7, and whenever the graphics switch from the Nvidia 330m chip to the Intel chip, the screen "flickers" black for a short moment before reappearing. Can anyone with a new MBP comment on this behavior? It doesn't happen on the switch from Intel->Nvidia, just the other way around.

I have two user accounts. On my one account (the main one) Safari works fine but on the other account just today it started loading real slow. then once it finally pops up with the home apple screen and you click anything, the wheel spins and spins for like 3 min then safari quits unexpectedly. When i click to report to apple and then send it, again the wheel spins for a long time and then it says it was unable to send to apple please check internet connection and try again. But, there is nothing wrong with my internet connection because if i switch to my other account internet works just fine!

View 1 Replies View RelatedLast night I was working in Adobe InDesign and Photoshop when my screen began to flicker like crazy and eventually froze. I could still move the cursor around but nothing would work. I couldn't force quit any of the applications or shut down the system. It eventually shut itself down and after restarting everything seemed normal. About 20 minutes later it did the same thing as I was switching between Safari windows using Expose'. (I recorded a small clip of the flickering and put it on youtube if that helps: [url]...?v=UBjRwRu4IOg ) After the second time this happened I again tried to start it up and it loaded to a gray screen, no startup chime, no apple logo. Nothing. I hit the power button and it shut down again. And the next time it booted all the way. I then shut it down with the intention of calling Apple Care today but apparently my Apple Care ran out in the last month or so. So, I'd have to pay $49 to talk to them about this issue. I thought I'd come here first.

I just moved back up to Jacksonville with my friend and now his iBook G4 is not booting. It goes to the white Apple screen and spins for about twice as long as normal, and then goes to a black screen with just a type-cursor in the top left hand corner which erases any text submitted. Now, from there I went ahead and booted from the Tiger Install disk and ran permission repair and also disk repair, without any glitches. Also, we then booted again and ran a hardware diagnostic and it turned up absolutely no problems with the computer. Any ideas? Luckily, he's still under his first year of AppleCare (and he's about to purchase an extension since you can now get it in Florida legally) and he should be covered.

Then tonight it just shut off instead of sleeping and now it won't start. All I can get if I'm lucky is the start up chime and a super quick flash of a white screen.

So I've had my 24" Al iMac ever since November 2007, good and everything until the past couple days, after extended use of the imac, everything is fine, screen is great, but when entering screensaver, its still great, its like a couple minutes or so into the screen saver when the top of my iMac's screen starts to flicker! When I move the mouse to get out of the screen saver, every thing is back to normal. It happens with all screen savers.
