If you suspect a problem with yourmonitor, see the documentation that comes with the monitor for instructions fortesting and adjusting the monitor. If you cannot diagnose the problem, call forservice.v Follow the suggested actions in the order in which they are listed in the Action column until the problem issolved.v See Chapter 5, “Parts listing,” on page 153 to check if a component is a consumable, structural, or FRU part.v If an action step is preceded by “(Trained technician only),” that step must be performed only by a trainedtechnician.Symptom ActionTesting the monitor. 1. Make sure that the monitor cables are firmly connected.2. Try using a different monitor on the server, or try using the monitor that isbeing tested on a different server.3. Run the diagnostic programs. If the monitor passes the diagnostic programs,the problem might be a video device driver.4.
