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.

		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.
	If the problem remains, call for service.
