Hi JJ Su,
To connect an external monitor to your MacBook Pro, you will need an adapter that connects to the mini-display port on the MBP, and has another plug that is appropriate for your external display {VGA or DVI}.
Take a look at Amazon to find a relatively inexpensive adapter if you don't already have one.
-Please make sure that you order the right kind of adapter for your MBP since there Apple has used 2 different kinds of ports depending on the particular model!
FYI, if the external monitor doesn't work either, then you probably have a bad GPU {Graphic Processor Unit} on the motherboard. IF the external does work, then you either have a bad internal screen, or some bad connectors/wires inside the MBP...
Hope this helps & good luck!

Mac book pro. Black screen cannot start but with boot sound


Have you tried connecting an external monitor.

A boot chime means the Mac has passed POST, that the screen remains black initially suggests there is a problem getting image to screen which could mean a bad cable to the LCD or the LCD display its self is having problems.

By connecting to an external display you verify the graphics on the logic board is functional, and it could get you up and running till the display problem is fixed.

Also try powering up and when you hear the chime, hold down the COMMAND+OPTION+P+R keys, and keep holding them till the machine has chimed 3 times, this will reset the 'BIOS' in case there is a glitch there stopping the display from showing up.

Vaio LCD problem


Periods.......Nice little items because they denote the End of a sentence.
See how this works?

"I have a vgn cs36gj, I was working with it, suddenly the LCD became pale black, I connected it to external monitor and it has a picture, sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

Now you try it.........

"I have a vgn cs36gj. I was working with it, suddenly the LCD became pale black.
I connected it to external monitor and it has a picture."

Okay, I got that part.........

"sometimes after turning on for 30 minutes LCD start working normally, but after turning off and disconnecting power when I turn it on, it only shows a pale black picture, you know it is on but only black!"

WHICH LCD?
Laptop LCD?
External monitor LCD?
Man on the moon LCD?

1) If the external monitor LCD goes 'pale black', the problem is the graphics chipset.
This I do not believe

2) If the laptop LCD goes pale black, this I believe.

Post back in a Comment.

My eee intel will turn on but the screen is black and the power lights will come on to when you turn it off it flashes white and thats it!Can someone help me please,


It'd be a good idea to check if the laptop is actually booting up or not getting anywhere at all. You can check this two ways, fairly accurately.

First of all, the best way to check is to plug your laptop into another external monitor, you should be able to do this with the VGA connector on the left side of your laptop. You can do this with any monitor that's used with a PC. See if the monitor turns on when the laptop starts.

If you don't have an external monitor to try, the numlock, caps lock and scroll lock keys on your keyboard should show that they're active by the LED that shows they're on or not. Turn it on and let it boot up (give it a few seconds or minutes to be sure), then press numlock or caps lock or scroll lock and see if the LEDs for those keys turn on or not.

If the external monitor works, or the LEDs are functioning as normal, it's likely that the monitor has a loose connection inside or that the monitor is entirely broken. Since the monitor is flashing white when you turn the laptop off, it would sound to me that the inbuilt monitor is connected but not working.

If the external monitor doesn't work, and the LEDs for capslock etc don't respond, then it's likely that something else is wrong with the laptop entirely.

It will be helpful to know what happens to narrow down additional help.

Black Screen Compaq Presario


Do you see the BIOS splash screen or anything?
Try booting into safe mode by pressing F* as soon as you power on the computer. If the monitor works, then it is a bad driver. Roll back to a previous restore point, boot to last known good coonfiguration. Last Known good configuration is available from the same as the safe mode screen.

If this is helpful, please comment and rate. Have any other questions, please let me know.

MX 6124 Gateway notebook screen stays black when powering up


Repaired! This sounde like a fuelty screen or screen inverter. To check this, connect to an external monitor, if the external works properly, then it's the screen or inverter. If the external doesn't work, let me know and we'll run the problem down to a more indepth (internal) trouble shoot.

Compaq Presario 1245 doesn't start up


Most laptops have a video connector that you can use to connect you laptop to an external monitor. connect an external monitor to your laptop and see if anythig comes up on the external monitor.Your laptop has a key to switch between it's own screen and the external monitor.When you use the external monitor ,you'll have to use this key to switch to the monitor.Your battery should'nt matter if the laptop is running on AC.Let me know what happens and we'll go from there.
