The screen is blank.
Verify that:
1. The system power cord is plugged into the system and a working
electrical outlet.
2. The monitor power cord is plugged into the monitor and a working
electrical outlet.
3. The monitor is turned on and the Brightness and Contrast controls are
adjusted correctly.
4. The monitor signal cable is connected to the correct connector on the
system.

The monitor works when
you turn on the system,
but goes blank when you
start some application
programs.
Verify that the primary monitor cable is connected to the video port.
To find the video port, see “Input/Output Connectors” on page 12.
Be sure that you installed the necessary device drivers for the
applications.

Professional or WinMode.
Wavy, unreadable,
rolling, distorted screen,
or screen jitter.
If the monitor self-tests show the monitor is OK, consider the location of
the monitor. Magnetic fields around other devices (such as transformers,
appliances, fluorescent lights, and other monitors) can cause screen jitter
or wavy, unreadable, rolling, or distorted screen images. If this happens,
turn off the monitor. (Moving a color monitor while it is turned on might
cause screen discoloration.) Then move the device and the monitor at
least 305 mm (12 in.) apart. Turn on the monitor.
Note:
1. To prevent diskette drive read/write errors. be sure the
distance between monitors and diskette drives is at least 76
mm (3 in.).
2. Non-IBM monitor cables might cause unpredictable problems.
3. An enhanced monitor cable with additional shielding is
available for the 9521 and 9527 monitors. For information
about the enhanced monitor cable, see your IBM reseller or
IBM marketing representative.
If the problem still exists, have the monitor and system serviced.
