Troubleshooting the DEB Installation
If a problem exists after installing the DEB, check the following:
If no display (blank video screen):
• Make sure the video monitor is plugged in—either to the
Display Enhancement Board or to the Video Display
Controller.
• Check to see if the 50-pin connector cable is correctly
! ! connected at both ends. It is possible to connect the cable so
that some of the pins are beyond the end of the connector.
(See "Installing the DEB.")
• Make sure both connectors are firmly seated in their
respective slots.
• If a Monochrome Monitor is connected, make sure the
-ft 15-volt connector is attached to the correct board. (See
j 1 "Installing Monitors.")
• If a Color Monitor is connected, make sure the ac power cord
on the monitor is plugged in.
