Hardware :: PowerBook With Bright Spot On Bottom Of Screen
Dec 24, 2008
I just bought a 12" powerbook from craigslist. The guy I bought it from powered it up outside in the sunlight so I didn't notice until I drove an hour home and booted it up. The bottom of the screen towards the very center is extremely bright compared to the rest of the screen. I discovered that if I push on the bezel right below the LCD, the screen normalizes. However, I can't see anything that looks bent, dented, or cracked anywhere on the screen, bezel, or back of the LCD.

Let me first apologize for this being very similar to one other topic in this section. However this is exactly what is happening to my computer and no one has answered the other guys thread ( similar to my post - agentphish - posted 01-19-2007, 08:19 AM).
I have searched through 50 of 77pages in this particular forum and my eyes are bugging out. Could someone please give me advice on this matter.
First, about 1 month or so ago I started noticing that in the bottom left and right corners of my screen, about the size of a nickel, it is a lighter color than that of the rest of the screen. It is hard to notice, but I do.
Now, I have recently begun to experience a large round dark area, just slightly smaller than the diameter of a CD in the lower left hand side of my 2 year old powerbook.
It only manifests itself when the computer has either been asleep or turned off for a period of time (typically the longest for me is a few hours during the day that it may be off or at most a period of overnight while I am sleeping)
It seems as though after 5-10 minutes it goes away presumably as the pixels are "warming up" or whatever it is that pixels do.

i have the new unibody white macbook. And sometimes when i am viewing pictures, there is a spot on the pic that looks like the screen would be broken (sorry i dont know how to explain this). This happens alot on almost every site sometimes though. Here is an example If you guys could please help me on this it would be great. You can see in the bottom pic what is wrong and it can look much worse on other pics like a bunch of little squares too.

This morning I noticed a soft white spot on the lower left corner of my Macbook. It's not a dead pixel. I've seen those before and this is different. This spot only shows up as a light spot when the screen has a light background. On a darker screen it totally disappears. The spot is a few mm in size and. I've examined the top of the LCD case and it's smooth. The Macbook has not been dropped in anyway.

I have a new MBA, 13" which I'm loving so far. I like the screen bright - like almost all the way up all the time. Other than shortening my battery life, will this setting cause any damage to the screen?

I've had bright spots appear behind my LCD screen for the second time this last month.
They look like the LEDS from the backlight are pushed up too close to the LCD and sort of washout the LCD in that area. The have occurred on the left side and the right sides along the lower edges of the screen.
I'm fed up with all the repairs this laptop has needed and feeling that I paid 2000 dollars for a quality product I went to the apple store today and asked for a replacement unit.
I was told that the recurring bright spots (on top of 3 other minor repairs and 1 major repair) did not warrant a replacement unit. The manager even said that they shouldn't have fixed this problem last time because it is cosmetic and not covered by the warranty. The genius also repeated the phase "This doesn't happen by itself" (I nice way to say I did this and that they shouldn't cover it. )
The manager decided to make me feel special and say something along the lines "We'll fix it again this time because we did last time".
My warranty is running out in 6 months and I need to know what's causing this. I always transport my laptop in an incase sleeve with a shoulder strap. There have never been any external marks on my casing when these dots appear. If I put too much pressure on the screen wouldn't the middle bend in more and I would get problems there? There weren't even marks on the screen from the keyboard keys yet I put enough pressure on it to cause this without even knowing it?
The best part is I asked the man who gave me my repaired laptop back how to prevent what the manager called 'LCD bruising'. When I mentioned bright spots he said 'Oh that's a defect we cover under warranty'.
Im going to contact apple's customer relations on monday regarding the repeated repair trips. I have no confidence this laptop can go a long period of time without needing repairs.

Why does my screen look dull? It's not dull like when you stop charging it, nor is it as bright as when it is charging, it's about in between. I have it plugged in and the battery constantly reads 95% never 100%. The little green dot is on the charger input and the battery symbol shows that it is being charged so I know it's charging. What reason would be why my screen is not as bright as before?

I bought a MBP last weekend, and noticed in the last few days a few bright "spots" on the screen in the top left hand area of the screen. It's like the complete opposite of a dead pixel - it's just bright and whitish. It's almost like a speck of glitter on the screen! It's only visable from certain angles, but is one of those annoying little things!

Have a late 09 i7 27" iMac with XP SP3 installed on Bootcamp partition. Even after turning down brightness in BootCamp control panel all the way down, I still feel like I'm staring at the sun. Screen is still way too bright. No such issue in OS X. Is there any Windows app (similar to Shades) that allows further brightness reduction? With brightness as is, Bootcamp is pretty much unusable to me.

I just got a new MBP 15 i5 2010 with a high-res anti-glare screen.
Manufacturer: 00000610
Model: 00009CBB
Serial Number: 00000000
Manufacture Date: 00000000
Unfortunately the display doesn't show very light colors. (compared to my old MBP15 2007) If you look at the attached image [URL]
- at section 5 I can only see the Grey boxes from 235 to 247, and I CAN'T see any Grey box from 249 to 253.
- at section 3 I can't see the Grey box at 5 all the other from 10 to 50 are fine.
Changing the brightness, playing around with different color profiles and resetting the system didn't solve this problem. I called Apple support and after some resets I was asked to compare my screen with the same make/year. Does anybody has the same 2010 MBP15 high-res anti-glare display and experiencing the same issue? Does your display work fine and is showing all the different Grey boxes?Other MBP owners: Can you see all Grey boxes on your MBP screen? My brothers 2009 MBP15 is showing all light Grey boxes from 235 to 251. 253 can't be seen

Has anybody seen this on their Macbook Air? A very bright, fading line of 6-8 mm at the top of the screen? I just returned my MBA because of this a couple of day ago. Then today I go to the local apple dealer (in Denmark) and I see the exact same bright line on the MBA screen in the shop. I also checked a unibody Macbook, a white Macbook, and an 24" iMac. None of these screens had the problem - it was only the Air. So now I wonder: is this a feature of the MBA, or was I right in returning it because of this.

I'm looking for a external monitor that is compairable in brightness as my iMac's screen. The brand needs to be Samsung, and the look of the Samsung moniter I would prefer to look like the examples below. Why? Because I want it to match my TV. I'm also looking for a small monitor because the space I have is pretty small and I dont want to have to move my iMac and look at it at a angle. I currently have a Samsung SyncMaster 906BW with a 1440 x 900 60hz resolution and its VERY dull compared to my iMac and its at 100% brightness and 85% contrast. Here are some of the screens I'm looking at so far, would they be close to as bright as my iMac's screen?

I just noticed that on a black background, my 17" i7 MacBook Pro has two areas in the lower middle area of the screen, where the backlight is too bright compared to the rest of the screen. It is very noticeable on a black background and grey.. Is anyone else having this problem?
Other things I noticed:
- there was dust on the plastic cover that you take off the case when you use it for the first time
- the aluminium enclosure was slightly dirty, could be rubbed off though..
- there are two minor 'impurities' in the aluminium (?!).. two tiny grey spots/blemishes basically
- there were a few minor scratches on the aluminium casing.
- the apple logo at the back glows in a much warmer (yellow-ish) colour than the previous generation mbp (?!)
- the screen seems not as bright as the previous generation
- the keyboard backlight seems not as bright as the previous generation

Our eMac seems to be developing a green tint in the bottom right hand corner of its screen. I've done some quick searching online and it seems that a few people have suggested a cold boot so it runs the degaussing process on a startup.
I left the eMac off for about an hour, unplugged. It did the degauss once it was plugged back in and "seems" to have removed nearly all of the green tint.
There are a few threads on various forums when I search on Google about this issue but they have no conclusive reasons why this is happening.
Could my eMac be developing a fault at all? I'm not too sure if anything magnetic has been placed on our table near the eMac so this may be the reason.
