When i turn my mac on a color screen appears that prevents me from do anything how can i trouble shoot this or fix this?

this color screen comes up once i turn on my laptop it doesnt allow me to operate my laptop or anything and sometimes it actually turns on but that same color screen ends up coming up in a matter of minutes, this color screen looks like that black and white screen a tv has when it has no cable instead its in color, is there a way to trouble shoot this? what can i do?

Does your model Macbook Pro qualify?
MacBook Pro: Distorted video or no video issues . The affected computers were manufactured between approximately May 2007 and September 2008.
MacBook Pro (Early 2008): Dark bands showing intermittently on built-in display

Hello, I have a MacBook Air, when I was watching a movie it started to freeze, so I turned off. But when I turn it on just the white screen appears nothing else. I looked on other websites, but the methods didn't help.

Try a Safe Mode boot ...
Startup your Mac in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient.
Once you are in Safe Mode, click Restart from the Apple () menu.

Restart with the Option key held down and see if the internal drive appears.
If it does, click on it, press Enter, and then change the setting in the Startup Disk pane of System Preferences or the Startup Disk control panel.
If it doesn't, insert a Mac OS install CD or DVD and use the Disk Utility or Disk First Aid to repair the internal drive. If there aren't any problems, install an OS onto it.

Have you verified that your TV is HDCP compliant? Consult manual and/or post model so someone can check.

I can't start my macbook pro because I turned it off when I got a trojan on my mac. When I turn my mac on I get the message that my computer restarted because of a problem. Then it turns off again and turns on again and it starts all over. What can I do?

Boot into your recovery partition (restart, hold down ⌘R until you see the Apple logo), and use Disk Utility to repair your hard drive. Repair permissions too while you're there. OS X: About OS X Recovery

When syncing any device, the device screen appears, but there is no text. How can I fix this?

When I connect my phone, iTunes shows the device. When you go to the device screen where you would see the serial number and the check boxes of what you're syncing, there is no text. The Sync and Apply buttons are there but no wording. The check boxes are there, but no wording next to it. So you don't know what you're syncing. I've tried uninstalling and reinstalling iTunes, but it still doesn't work. And it happens with all 5 devices that I sync.

That generally indicates trouble with the Segoe UI fonts on your system, shannon.
Unfortunately, it's a bit trickier to deal with on Windows 7 than other Windows operating systems. (The instructions by Vortical that usually fix it on Vista and XP can't be applied on a Windows 7 system.)
Try having a look through the following (unfortunately rather long) topic for discussions of possible causes of the issue on Windows 7 systems, and possible treatments for the various font-related issues on Windows 7:

Why may mac starts all programmes (word, excel..etc), when I turn my mac on?

Make sure that Open at Login is not selected?
... and that you have not checked the box "Reopen windows when logging back in"?
... and Word, Excel etc are not included in the items listed in System Preferences > Users & Groups > Login Items?

I bought my iPhone on Friday and when I tried to use it to make a call the screen had turned green - as if a green filter had been placed over it. When I turned the phone sideways the color turned to magenta. Anyone else have this problem?

If you keep getting a 'red' message it means that the HDD is faulty and will have to be replaced. You will have to format the new HDD in Disk Utility>Erase and then install the OSX and your data from Time Machine.
Ciao.

I only see the phone numbers of my contacts when using iMessage on my MAC, whereas I see the names on my iPhone. Why, and how can I make it so I see the names (and pics) on my MAC?

Thanks Eric, but that was already turned on. I just now tried turning it off and on again, no change. Actually, I"m more interested in seeing the names than the pictures. I now only see the phone numbers and generic avatars where pics would be.

My Outlook/iCloud calendar invites to others appear to work on my end and sync with my PC and mobile, but when other people "accept" the invite, it will not populate/add in to their calendar. How can i fix this without turning off iCloud?

My Outlook/iCloud calendar invites to others appear to work on my end and sync with my PC and mobile, but when other people "accept" the invite, it will not populate/add in to their calendar. How can I fix this without turning off iCloud?
I am at a new office that uses Outlook (not Outlook Exchange) which does not sync with my mobile... I just got iCloud set up on my PC to sync my contacts, calendar, reminders, etc... The sync worked (not without flaws, but the other issues seem solvable... I think), so that i can now see all my appointments on both my phone and on my PC. The problem I am having is that iCloud moved all of my calendar items from Outlook into iCloud calendar and now when I send out meeting/calendar invites the recipients may accept them, but the meeting does not get added to their calendar. This is a huge problem and may mean that i need to turn off iCloud.
Does anyone know how to fix this?
Thanks!

I am replying to my own post here as I seem to have fixed the problem.
I do have some calendars that are shared. Some of those are shared with users who have time zone support turned on. So i activated time zone support on my iphone, then deleted my icloud subscription. I then signed in to icloud again and voila... problem solved.
It is a weird one as the other calendar views were always fine and when you opened an event that appeared in the wrong day (on list view), the correct date of the event was shown in the information...
one more bug in a complicated system I guess

When i turn my mac on a color screen appears that prevents me from do anything how can i trouble shoot this or fix this?
