The video expansion board failed. Monitor does not function properly when used with energy saver features. Video colors are wrong. Monitor without energy saver capabilities is being used with energy saver features enabled. Either the cabling or the monitor impedance is incorrect. Slow-moving horizontal lines are displayed. Magnetic field interference is occurring. Possible Solution Press any key or type your password, and then wait a few moments for the screen to activate.

If you do not have access to the password, you must disable the power-on password by using the Password Disable switch on the system board. Refer to your server-specific user documentation for further information. Check Insight Manager 7 (or previous version) messages for references to video expansion board failure. Be sure that the PCI Hot Plug slot has power. Check the power LED on the slot. Be sure that the server and the operating system support the expansion board. Disable the monitor energy saver features. • Be sure that the red, green, and blue BNC cables are connected to the corresponding monitor connectors. • Be sure that your monitor RGB inputs are set to 75 ohms. Move the monitor away from other monitors or power transformers. 2-36 HP Servers Troubleshooting Guide
