Troubleshooting the Computer Screen (LCD)
Why did the computer (LCD) screen go blank?
 Your computer screen may go blank if the computer has lost power or is in a power saving mode (Standby or
Hibernate).
 Make sure the computer is plugged into a power source and is turned on. The power indicator on the
computer will be on if the computer is on.
 Make sure the battery is inserted properly and is charged.
 If the computer is in LCD (Video) Standby mode, press any key to activate the computer screen.
 If the display mode is set to external display (such as TV), press and hold the Fn key while you press F7 several
times.

How do I change the video resolution on the TV screen?

resolution to 640 x 480 pixels.)
