MacBook Pro :: Computer Starts With Gray Apple Screen Then Turns White

Sep 29, 2010

I am trying to fix a friends macbook pro. When I turn it on the screen shows the apple and the spiral underneath it spinning like it should then when it stalls for .2 seconds it goes to a white screen then there is vertical purple lines in groups across the screen. So the screen is white/purple. Then it fades to just white and I cant do anything.

I hooked up my monitor with a DVI cable to see if it was the motherboard that was possibly bad but the monitor works just fine with the cable. I can use the computer with the laptop keyboard/mouse and it works just fine. The laptop screen just stays blank the whole time. I uploaded a vid to utube for it. If anybody has any ideas for me please help. I dont know if this is a monitor problem or the inverter or the motherboard, possibly some other piece of hardware?

Intel Mac :: White Sun Stripes From The Top Of The Screen

May 10, 2012

I own a 3year old iMac 24" model 2008. On the top of the screen theres appeared some white "sun"-alike stripes.

I got the iMac from someone which unfortunately is a smoker, so the first thing i did was cleaning the glass, which did alot for the fuzzy smudges. But theres something wrong in the LCD screen itself. 

My observation are that its easier to see when theres backlight, so when the screen is black its almost not visible. 

I wonder if theres any chance that dust/smoke has got its way inside of the LCD even though the stripes look way too symmetric.

MacBook Pro :: Green And Purple Vertical Stripes And Not Rebooting?

Sep 1, 2009

while surfing the internet (I was reading an article on CNN and scrolling down to continue reading), the screen color changed to tinges of green and purple. The entire thing froze...no keys, no mouse, not even force quit...nothing. I had no choice but to do a hard shut down by holding down the power button until the laptop just shut off (Macbook Pro). In the middle of rebooting, (at the grey screen with the apple logo on it, I got the familiar circular dial that ticks around as it loads) a screen wipe similar to the effect of some screen savers went from the top of the screen to the bottom turning the screen from grey into green and purple vertical stripes.

It also said "you need to restart your computer" and proceeded to tell me how to do so in four different languages. Upon doing so, the same thing happened...several times. I tried booting it into safe mode by holding down the shift key until the grey apple background appeared and it seemed to be working as the loading was taking forever. Alas, the same thing happened. I took the battery out and held down the power button for 10 seconds, put the battery back in only to suffer the same effect. The next genius bar reservation isn't until Friday.

MacBook :: Screen Turns White - Starts Ticking - Envelope With?

Apr 5, 2010

I was reading a recipe the other night and my Macbook started ticking, the screen went black, then a white screen came up with a blinking envelope with a "?" in it. This happened once before when the computer was about a year old. I took it to the Apple store and they repaired it. The problem is that store is 2 hours from me. Does anyone know what this is and how to fix it? I have hit different keys and nothing takes me out of that screen. My biggest concern is my pictures and music are on it. I plan to buy another computer (anything but Apple) if I can't come up with a fix for this. Is there any way to get my music on my Iphone onto another computer?

MacBook Pro :: Mavericks Screen Fades White

Jun 27, 2014

I'm using macbook pro 13" late 2012 (2.5 GHz, 8GB RAM), with mavericks. As from the last week, the screen fades to white as shows in the attached picture.

At first, the phenomenon occurred just  for parts of the screen - the area below windows got a mark of that window after I closed it with a faded white color. Now it's all the screen.

Notably, the colors on a second screen I tried to connect via thunderbolt are normal. However, I do believe that it's not an harder problem as it sometimes works properly - when I waked it up today it was normal for a few minutes.

I'm tried restarting, reseting SMC & PRAM and logging in with new user account, without success.

MacBook Pro :: Colorful Stripes/lines On Screen?

Mar 25, 2012

So at some point before, i noticed this line of colors on the left side of my mac, althrough its not bad it became bigger; still i ignored it anyway. Then just a while ago i saw another small colorful line on the right, its way smaller than the other line which has the length of the entire screen. But i want to get rid of the lines already, its only really visible when i have a white screen, but it is still noticable without a white screen. i don't know if its just a bug on my mac, or a hardware fail. The lines when i look at it is like seeing a hypnotic ray when i move...

MacBook Pro :: Vertical Stripes At Boot Then Black Screen?

Feb 23, 2010

I have a MacBook Pro with Leopard. On boot, I get a screen of vertical blue stripes with the Apple logo, sometimes intact, sometimes split across the stripes. The spinning activity wheel is there too. After about 30 seconds, it gives up the ghost and the screen goes blank. It's still powered on, but just the screen is blank.

I've attached an image of what the screen looks like.

I've tried Command Option PR to reset the PRAM and VRAM but the problem remains. Any ideas?

OS X Mavericks :: Can't Get Past White Loading A Screen After Restoring From Time Machine Backup

Jun 21, 2014

I am aware there are others threads of my problem however they date back years ago and after trying their solutions it still does not work. 

After using Time Machine to restore my hard drive from a backup, I can't get past the white loading screen with apple logo after system restart during restore process. Ive gone into disk utility and repaired hard drive - it's fine. So I know this is a software glitch. I've also tried resetting SMC & PRAM (whatever those mean). No success and i cannot get past the white loading screen. 

I'm running Mavericks (latest) on a late 2009 iMac

EMac :: Screen Went Purple And Was Shaking And Then It Just Died

Apr 19, 2012

I came home and found an eMac on my back porch, came from my moms friend apparently. so i plugged it in and turned it on and i was playing on it for a while but safari would just repeatedly crash after loading the home page, so i restarted it and it seemed to fix the problem, me and my friend then took the casing off and replaced the cd drive because it was jammed. it started up just fine after that but after the next restart the screen seemed to be "shaking". it was jumping left to right. so i powered it off and started it up again. this time it did the same thing but it was more vigorous and the screen was flashing from normal to a dark purple tint. then it went really dark purple, the screen shut off, then the whole computer shut itself off. now only after leaving it unplugged for at least 30 seconds the first or second push of the power button will "twitch" the fan and the CRT sounds like its trying to come on, but i only get the CRT sound and the fan maybe doing at most a quarter turn before it stops. the only changes made was a new cd drive and a second RAM card. i tried it by pulling out the added ram card and still nothing. then tried with the cd drive IDE cable removed and still nothing.

MacBook :: Screen Colors Faded (bluish Purple)

May 31, 2009

1. Today, I turned on my MacBook running 10.5.7 bought in the Summer of 2006 and the colors were washed out/faded. They were noticeably more bluish-purple. This is the third time it happened over the past year, so it is incredibly hard to replicate for a genius. A restart fixed the issue. I did not mess with the color schemes (I actually don't even know how to use them), nor have I dropped my laptop in the past three years I have owned it. Anyone know what is the issue here? I'm pretty sure it's hardware-related. I am concerned because my AppleCare is expiring this coming September, and I don't know how to replicate the problem.

2. Also, after a good period of nonuse, one-fourth of my screen (the lower left corner) is noticeably "darker" after I turn it on. The area goes back to its correct brightness after 10-15 minutes, like the screen has to warm up first. I've had this problem since I first purchased the unit but this dark spot has definitely gotten bigger. Is this normal for a laptop?

3. Coconut battery says that I have only gone through 4 battery cycles. I've calibrated the battery and the program still says the same thing. The battery I replaced quite a while ago did not have this problem.

MacBook Pro :: Strange Purple Lines In Pattern On Screen

May 3, 2010

i have had a Macbook Pro which I got in mid 2008 and it just yesterday began doing something strange. After working in Mac OS X for a while I saw that many of the white areas on my screen were filled with purple lines. Most of my pics in my background are outlined with varying colors and I cannot figure out what is going on.

I began to suspect the graphics chip at first, so to test this theory I plugged it into an external display and the problem did not exist there so I concluded that it was not due to the graphics chip. I have a friend who performed some tests and believes that it is a problem in the connection between the monitor and the graphics chip and that certain bits of data just aren't making it through. I thought that this was a feasible problem, but to get a second opinion I took it to the local apple store on my university campus and they looked at it and also concluded that it was not a graphics chip problem, but that I may have to replace the whole display assembly. This was fairly expensive and I cannot afford to do that since time got away from me and I forgot to purchase applecare. (How stupid of me. Aargh!) Anyway, so I was wondering what is believed by the macrumors community to be the best option. I discovered that this problem seemed to happen on a lot of this particular model of macbook pro and that apple offered to replace the graphics chip for free because of it, but since they do not think it is a graphics chip issue, it appears that I am stuck.

Hardware :: Green And Purple Blotches Appearing On Screen ... Macbook Pro

May 5, 2008

I have a first generation macbook pro, recently i have been getting neon green and purple blotches appearing on my screen. I was also having a hard drive problem so i swapped that out and installed a fresh copy of OSX 10.4 on there and was still having the green and purple show up so I know that it is hardware related. I also have hooked up an external monitor and they show up on that monitor too so I konw the problem is not related to my monitor.. I downloaded fan control and have found that if I keep my macbook under 53 degrees C then They wont show up nearly as often but they still do. The only problem with this is that to keep it under 53 degrees C then I need to have the fans running extremely fast the entire time which is not really solving the problem...any suggestions?

It kinda looks to me like I need to get the logic board replaced, what does that entail.. can I do it myself? im pretty good with computers and electronics. I don't have apple care and the warrenty has definelty been voided or is expired..what kind of $$ am I looking at?
