Being a whole vertical row of pixels, I'm afraid it does sound like dead pixels on the LCD.

Before splashing out on a new LCD it would be worth re-seating the connection to the screen. The cable goes up through the hinge so wIth the constant opening and closing the cable can get moved or pinched. I have seen that in the past. Normally that would effect the whole display but it's worth a look at.

Have you had a mac techie look at it? They would check for that before charging you for a new LCD.
You can save some money by picking up spares on ebay. Just depends on if you are confident enough to fit it yourself. As it is not that easy!

Sorry I cannot be of more help.

    Thanks for the doing the movie. Yep, the problem is what I thought. The only way to fix that one is replace the screen. Shame you are out of warranty, always happens just as you go out of warranty!

    I have a machine with the same problem. I just got an external monitor. They are quite cheap now so it is a could solution if you don't mind the mac being confined to your desk. Just get a nice big monitor!

    You can always look out on ebay for a 'mac for spares' some people sell theirs when the logic board or such goes (that is exspensive to fix and in most cases not worth replacing) The screen is quite easy to replace if it is still inside the lid.

    Good luck.

This sounds like a problem with the connector, or cable, rather than the LCD screen itself. If the screen is fine while pressing on it, it's probably Ok. My similar problem turned out to be the cable. has great troubleshooting and repair advice. (Your pressing finger getting tired yet?)

MacBook Pro won't boot at all

It's hard to say without more information. When you say it doesn't boot, does the screen come on at all? (the first thing that shows during a boot attempt is a gray screen). If the screen does come on, what does it show? Also what year is the macbook pro?

White screen of death on Macbook 13". when turning

You may need to reset the PRAM.
Start your computer and hold down the option, command (apple), P and R keys simultaneously until you hear the second chime. Then release.

This will reset the perimeter RAM (PRAM) and may allow your system to start, which it will do immediately if it capable.
If this is not the case and you have already tried removing the RAM and the HD, you may need to have the motherboard tested.

InstallatIon of Mac OS X 10.4.10

White screen issues on your Macbook are more often than not, an indication that you may have a connected peripheral or device which may be hindering your Macbook's normal start up function

What you need to do first, is remove all peripherals from (printers, scanners, USB drives etc.) and then reboot your Macbook.

If your Macbook starts up normally without a white screen, leave all the peripherals disconnected and see if you can proceed to run all of your software updates, in Apple menu>Software Updates, first, including updating to the final version of Mac OS X 10.4 Tiger, 10.4.11.

Once all of your updates are completed, then you will need to go through a process of elimination by connecting one peripheral at a time, then properly shutting down and restarting your Macbook with each device, to see if your Macbook goes to a White screen.

Depending on the number of peripherals you have normally connected to your Macbook, this may seem a little tedious at first. But considering how bothersome a White screen is, it will be worth it solving the mystery of which peripheral is causing the white screen and failure to boot up normally.

If it turns out that one of the devices you had connected was in fact, causing the white screen, this will be the opportunity for to research online, visiting the affected device's manufacturer's website or even use Google, to confirm if there are any known issues and/or updates available to address that issue.

There are other variables which can come into view with a white screen issue, but this is a good way to start in terms of working toward a viable solution to this issue with your Macbook.

I hope this helps, let me know if you have more questions.

My macbook is frozen with the folder icon showing on a blank screen with a question mark on it? Help

It sounds like your MacBook can not find the system software to boot up. This is often a sign of a hard drive going bad. Try booting from the CD/DVD that came with your MacBook and running Disk Utility.

Good luck!
I hope this helps.

MacBook startup problem

To get a disk out of a mac hold the mouse button down whist the the machine is booting up and it should eject automatically.
WIngammon, try this.
hold Command - option P R straight after you turn your mac on. This will reset the PRAM and NVRAM. this might help.
otherwise if you have an original or copied osx install disc try booting up from that by turning on your computer, inserting the disc and then turning it off again. Give it 5-10 secs and then boot up again holding the C key. this should take you a screen similar to the login screen, you will have to choose a language. In the toolbar(top of the screen) you should go to utilities and select disc repair.
I have had this problem with my own macbook and the above things have solved it for me. However its possible that the same symptom my not be caused my the same problem.
Best of luck.
Let me know how it goes.
