v Follow the suggested actions in the order in which they are listed in the Action column until the problem is solved. v See the Problem Determination and Service Guide on the IBM System x Documentation CD to determine which components are customer replaceable units (CRU) and which components are field replaceable units (FRU). v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a trained service technician. Symptom Action Testing 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 is being 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. Reseat the Remote Supervisor Adapter II SlimLine. 5. Replace the following components one at a time, in the order shown, restarting the server each time: a. Remote Supervisor Adapter II SlimLine b. (Trained service technician only) System board The screen is blank. 1. If the server is attached to a KVM switch, bypass the KVM switch to eliminate it as a possible cause of the problem: connect the monitor cable directly to the correct connector on the rear of the server. 2. Make sure that: v The server is turned on. If there is no power to the server, see "Power problems" on page 86. v The monitor cables are connected correctly. v The monitor is turned on and the brightness and contrast controls are adjusted correctly. v No beep codes sound when the server is turned on. Important: In some memory configurations, the 3-3-3 beep code might sound during POST, followed by a blank monitor screen. If this occurs and the Boot Fail Count option in the Start Options of the Configuration/Setup Utility program is enabled, you must restart the server three times to reset the configuration settings to the default configuration (the memory connector or bank of connectors enabled). 3. Make sure that the correct server is controlling the monitor, if applicable. 4. See the Problem Determination and Service Guide on the IBM System x Documentation CD. The monitor works when you turn on the server, but the screen goes blank when you start some application programs. If the problem remains, call for service. 1. Make sure that: v The application program is not setting a display mode that is higher than the capability of the monitor. v You installed the necessary device drivers for the application. 2. Run video diagnostics (see the Problem Determination and Service Guide on the IBM System x Documentation CD). v If the server passes the video diagnostics, the video is good; see the Problem Determination and Service Guide on the IBM Documentation CD that comes with your system. v (Trained service technician only) If the server fails the video diagnostics, replace the system board. If the problem remains, call for service. Chapter 5. Solving problems 83
