I assume you are saying the screen is totally black, not blue. If it is totally black there can be a large number of causes. It is hard to give one simple answer. It could relate to the brighteness of the screen, the display, the logic board, the graphics card or even a problem relating to updating Apple firmware, You could try some simple things first.1) If the lighting on your computer is accidentally turned all the way down, your screen will be black! To turn the brighteness up, push F2 on the top of your keyboard and click until the lighting improves and you see the screen. If your display stays black it could be an indication that you just need a new Display. They do wear out. 2) Another thing to try is to start the computer in Safe mode. http://support.apple.com/kb/HT1564?viewlocale=en_US As you push the power button hold the shift key down. This can sometimes help resolve issues relating to startups. Also, if your screen stops being black it is an indication there is nothing wrong with your display. 3) You could try resetting the PRAM http://support.apple.com/kb/ht1379, This can also help with a startup issue. 4) Some specific models of Macbook Pro computors have issues caused by the NVIDIA graphics card, which Apple knows about and apparently will repair, possibly free of charge. My suggestion if none of this helps is to take it to a Genius bar at an Apple store for them to troubleshoot. That, in itself, costs nothing. Other suggestion search with google for further answers from other Mac owners!

Can hear sound but cannot see picture


Hi, if your LCD projector turns on and projects light with sound but not the picture on your computer screen, first make sure the projector is plugged into your computer. If it is, check your computer display settings. Go to "Control Panel" and "Settings" or "Windows Setup." Select "Display." Make sure it's set to appear on your laptop screen and the the projector screen. Most laptops have a "Fn" key dedicated to changing the output display setting.


If your projector turns on but emits no light or picture, replace the projector's bulb, often called the lamp. Most have a life of between 2,000 and 6,000 hours. Your projector may warn you when the lamp life is about to expire, although some models simply stop working when the lamp needs replacing.



Thank you.

Test the laptop using an external monitor
If this works fine, then the issue is with the screen, or possibly the vga cable. I notice this is referred to as a compatible screen, was this obtained new, or is it 2nd hand. Although most 15.4 screens fit most 15.4 laptops, some do not display correctly, this might be your problem. If you know the screen to be good I would suspect the connection at the back of the screen

If this still shows issues with an external monitor, you have a problem with your graphics chip on the motherboard

No screen


If you are suffering from a no display issue it is important to discover if it is a problem is due to a loose cable, LCD/inverter issue or a faulty GPU/system board. The fastest way to diagnose such an issue is to connect an external display to your video out port (preferably a VGA port although some newer laptops use HDMI or DisplayPort instead) and turn on the laptop. If an image is displayed on your external display then you have ruled out the GPU being faulty, although the system board still may be faulty. <br /> Next check your laptop LCD, is there an incredibly dim image being displayed? If so then a loose LCD cable could cause the problem, a very basic way to test this would be to apply pressure to various parts of the laptop case and screen bezel, also move the screen and see if a backlight ever powers on. If you are comfortable opening your laptop to check connections then do so. A faulty cable is also a possibility. Sometimes it is a software issue, try turning your display brightness up to max, does the backlight illuminate when in BIOS? If so it is a software problem. Finally it could be a failed LCD inverter, this is a bit of hardware usually separate from the LCD although is sometimes built onto it. These are generally easy and reasonably cheap to replace.<br /> If there is no image on the display at all then follow the above instructions to check your LCD cables and connections. If you have an image at POST but when booting to OS the image disappears then it is a software fault with your OS. Consider a format and fresh install if there is no important data to recover.<br /> <span style="font-size:12.0pt;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;; mso-fareast-font-family:&quot;Times New Roman&quot;;color:black;mso-fareast-language: EN-GB">Hope this helps,</span><br /> <span style="font-size:12.0pt;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;; mso-fareast-font-family:&quot;Times New Roman&quot;;color:black;mso-fareast-language: EN-GB"><a href="http://www.putercare.com/">www.PuterCare.com</a></span><br />

Intermittent monitor outages with MPC Transport T1200? Should I replace monitor or check wiring and how? New-to-me laptop, upon powering on no picture was visible, could hear all normal sounds of...


Looking through your owners manual, there are several keyboard shortcuts that can at least increase the appearance, although it sounds like a simple connection problem. Very hard to find a repair manual, although most transport laptops have a very thin multiwire cable connecting the monitor to the keyboard. Sounds like that cable has one or more wires broken, or just possibly a bad connection where the cable connects to the mbd. If you have the expertise to disassemble and repair, those cables are available at many places like Fry's Electronics, however many are soldered in place and require quite a bit of technical expertise to replace. I would suggest doing some price shopping at some of your local repair shops.Here is what the manual says: Problem
Action
The display panel is blank when the system is turned on
  • Make sure the TransPort T1200 is not in the Standby or Hibernate suspend modes. The display is turned off to conserve energy in these modes.
The screen is difficult to read
  • The display resolution should at least be set to at least1024x768 for optimal viewing.
  1. Go to [Start > Settings > Control Panel] and double-click the Display icon.
  2. Under the Settings page, set screen resolution to at least 1024x768 and choose at least 256 colors.
The screen flickers
It is normal if the display flickers a few times during shutting down or powering up.
Nothing appears on the screen.
  • During operation, the screen may automatically turn off as a result of power management. Press any key to see if the screen comes back.
  • The brightness level might be too low. Increase brightness by pressing [Fn+F7].
  • The display output might be set to an external device. To switch the display back to the LCD, press [Fn+F5], or change the display through the settings in Display Properties.
The characters on the screen are dim.
Adjust the brightness and/or contrast.

Laptop inverter problem


you have major problem here - the power regulator on the motherboard which regulates the line voltage down to 12V to feed the inverter, and battery voltage /up/ to 12V to do the same, is blown. I've seen this happen in HP laptops - line voltage to the inverter on mains power reads at 18.2-18.5V (which overloads the inverter), on battery it reads 10.5-11 (which won't fire the inverter). This is usually a sign of a bigger problem. Usually one that involves replacing the motherboard.

you have a bad inverter board, this feeds hi-voltage to the lamps that create the display. common for LCD screens
or the back light lamp.
