4866 LX/T  (250-5144) Troubleshooting the Video Adapter Faxback Doc. # 1499

The following is a list of some typical symptoms of problems you might have with 
the video adapter, along with possible solutions:

One long beep and two short beeps when you turn on the system:

* The video adapter is not seated properly in the expansion slot. Reseat the
  adapter, being sure that it is secure.
* The expansion slot connector on the video adapter is not clean. Clean the
  edge connectors with a clean pencil eraser. Use cuation because the gold
  plating it thin and will not stand up to severe abrasion. To avoid leaving
  residue on the connectors, do not touch them with you bare hand.
* If cleaning and reseating does not solve the problem, contact your computer
  dealer for assistance.

No Display:

* There is a loose connection. Be sure that the adapter is firmly seated and 
  that the monitor power cable and the monitor signal cable are securely 
  connected.
* The system is not configured correctly. Review the installation procedures 
  to ensure that the system is configured correctly.
* The monitor is not turned on.
* The brightness and/or contrast controls are not adjusted correctly.
  Re-adjust the controls.
* The jumper and/or switch settings are incorrect. Verify that all jumpers and
  switches are set correctly.

F1 SETUP error when you start up your system:

* The setup utility was not run correctly. See the "Configuring Your System" 
  section for information on running the setup utility.
* The battery in the computer might be dead.

Display rolls horizontally or vertically:

* You are using inappropriate software. Verify that you are using the correct 
  software files for your monitor.

Image is offset on monitor:

* You need to adjust the monitor centering. Refer to your monitor 
  documentation.

Distorted images or a blank screen when you run your software:

* The software is not configured for the current video configuration of the 
  adapter. Reconfigure the software for VGA or EGA video.
* The software is not compatible with the current video configuration of the 
  adapter. Set the adapter to a video standard supported by the software.
