Video Troubleshooting and Maintenance
Solving most graphics adapter and monitor problems is fairly simple, but costly, because replacing
the adapter or display is the normal procedure. Except for specialized CAD or graphics workstation-
oriented adapters, virtually all of today's adapters cost more to service than to replace, and the
documentation required to service the hardware properly is not always available. You can't get
schematic diagrams, parts lists, wiring diagrams, and other documents for most adapters or monitors.
However, before you replace an apparently failed component, be sure you have exhausted all your
other options. These include following the troubleshooting tips in the next section and checking the
warranty status of your device.
Tip
If you're not in the habit of registering newly purchased products, it's a good habit to pick up.
Registering your hardware helps to verify warranty status, sometimes provides longer warranty
coverage for your equipment, and helps the vendor reach you with updates or service
advisories.
Remember also that many of the problems you might encounter with modern video adapters and
displays are related to the drivers that control these devices rather than to the hardware. Be sure you
have the latest and proper drivers before you attempt to have the hardware repaired; a solution might
already be available.
