Screen on my macbook 13" won't stay on. It just flashes once and goes off.

I've tried everything but nothing seems to work. I have a new Display inverter but the problem is not solved. What happens is that when i turn it on the display flashes once and then it goes black. When i hit the display's intensity bottoms it just flashes but won't stay on. Any suggestions? please! i can't find any apple technician around here as this is a very (very) small town. Help!

Resetting your Mac's PRAM and NVRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
Restart the computer in Safe Mode, then restart again, normally. If this doesn't help, then:
Reinstalling Mavericks, Lion/Mountain Lion Without Erasing the Drive
Boot to the Recovery HD: Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Repair the Hard Drive and Permissions: Upon startup select Disk Utility from the main menu. Repair the Hard Drive and Permissions as follows.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu.
Reinstall Lion/Mountain Lion, Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Continue button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.
If you are not using Lion, Mountain Lion, or Mavericks then use the following procedure:

1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.

Ok, in theory you cannot lock the hard drive, so, run Disk Utlities, First Aid, Repair Hard Drive again. It should come back with a message that all is OK. Then run Repair Permissions. That often returns a lot of messages that are not actually problems, just grumbling by the system.
Then try a normal restart by clicking the apple left side of the menu bar, Restart. If you restart normally all is fine.
If not, then restart on the recovery HD again and try an Install Mac OS X and see if that succeeds this time.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds.

MacBook Pro won't stay asleep with external monitor attached. When sleep is selected from the Apple menu the computer will go to sleep only to continually wake up...go back to sleep...wake up...etc. every few seconds. This only happens when using the external monitor. Does anyone have any suggestions?

Mine does that too. The worst thing is when it goes to sleep, then wakes up and keeps running while the lid is closed and it is wrapped up in a case. I am afraid when the hot weather comes it is going to burn up. I am hoping Apple fixes it in the software or they may have a melted MBP to replace.
Then when I open the lid it is crashed running at fill tilt, pumping out heat to beat the band. I am forced to hold the button down and reboot.
I wiped my hard disk and reinstalled my OS, but it didn't help. I reversed my OS to 10.5.0 and it solved the DVI problem but still won't sleep. This post will probably be deleted by Apple, they did it a few days ago. I just don't know what to do, and I consider myself a real Apple expert. Just hoping you realize you are not the only one.

Try a safe boot.

This boot takes longer than a normal boot, be patient. If it boots login, and see if it seems normal. If so, logout and reboot normal.

When I turn on a video the screen on my MacBook Pro freezes. I've been through Apple Care and they couldn't fix the computer. I think the fan and the graphics are the problems. I can restart after two attempts. Sometimes I use SAFEBOOT

Please advise the model MBP you have and the OSX you have installed.
Also try a SMC reset:

Hello KCC4ME,
You may try booting your Mac in Safe Boot, as it can resolve many issues that may prevent a successful login.
OS X: What is Safe Boot, Safe Mode?
http://support.apple.com/kb/HT1564
If a Safe Boot allows you to successfully log in, you may have issues with one or more login itmes (while the following article is labelled as a Mavericks article, it is viable for earlier versions of the Mac OS, as well).

My Macbook Pro Stops running as normal, when it is not connected to the charger. Once it goes off the plug, it slows down to a point where it is not usable.

Are the lines like psychedelic herringbone? If yes, I had that happen once, it was something serious, like the
Logic board. The good news is that it was fixed without any loss of data on the hard drive. Take it in to have Apple look at it ASAP. I took it to TekServe at the time, they are very nice about preserving your data and user library when possible.
Good luck and don't panic.

My Macbook Air won't stay on

I received a new Macbook Air for christmas and trtied to use tonight but it wont work. I press the on button, the keys light up, an arrow comes up on the screen and then within seconds it goes off. Can anyone help?

First, I would confirm that your charger is properly connected. You should see an orange or green light on the plug when it is connected to the Air. Try to power up with the power connected.
Otherwise, it might be in your best interest to make an appointment at the Genius bar at your local store. If it is new out of the box, then you should be able to get support from them.
