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:
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.
Go to [Start > Settings > Control Panel] and double-click the Display icon.
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.
