Monitor problems Symptom FRU/action The screen is blank. 1. Verify that: v The server power cord is plugged into the server, and into a working electrical outlet or power distribution unit. v The monitor cables are connected correctly. v The monitor is turned on and the brightness and contrast controls are adjusted correctly. Important: In some memory configurations, the 3-3-3 beep code might sound during POST followed by a blank display screen. If this occurs and the Boot Fail Count feature in the Start Options of the Configuration/Setup Utility program is set to enabled (its default setting), you must restart the server three times to force the system BIOS code to reset the configuration settings to the default configuration (memory connector or bank of connectors enabled). 2. If you have verified these items and the screen remains blank, replace: a. Monitor b. Remote Supervisor Adapter II. c. I/O board Only the cursor appears. v See "Undetermined problems" on page 136. The monitor works when you turn on the server but goes blank when you start some application programs. 1. Verify that: v The application program is not setting a display mode higher than the capability of the monitor. v The primary monitor cable is connected to the optional Remote Supervisor Adapter II or C2T breakout cable. v You installed the necessary device drivers for the applications. 2. Monitor. 3. Remote Supervisor Adapter II. 4. I/O board. The monitor has screen jitter, or 1. If the monitor self-tests show the monitor is working properly, consider the screen image is wavy, the location of the monitor. Magnetic fields around other devices (such as unreadable, rolling, or distorted. transformers, appliances, fluorescent lights, and other monitors) can cause screen jitter or wavy, unreadable, rolling, or distorted screen images. If this happens, turn off the monitor. Attention: Moving a color monitor while it is turned on might cause screen discoloration. Move the device and the monitor at least 305 mm (12 in.) apart, and turn on the monitor. Notes: a. To prevent diskette drive read/write errors, be sure the distance between monitors and diskette drives is at least 76 mm (3 in.). b. Non-IBM monitor cables might cause unpredictable problems. c. An enhanced monitor cable with additional shielding is available for the 9521 and 9527 monitors. For information about the enhanced monitor cable, contact your IBM reseller or IBM marketing representative. 2. Monitor. 3. Remote Supervisor Adapter II. 4.
