Configuration Problems - HP LP 1000r Service Manual

Chapter 5
If a monitor tester is available, use it to check the display.
◊ ◊ ◊ ◊
If you suspect the monitor is faulty, replace it with a known good monitor. Then reinstall the
◊ ◊ ◊ ◊
original monitor and duplicate the error.
12. Verify the monitor is working by plugging it into a know-good Netserver or computer.
13. Check to see if the monitor connector's pins are bent. If the pins are bent, slowly but carefully
straighten each pin.
14. Connect the monitor cable to the Netserver video connector and turn on the Netserver. If there
is a display, but characters are the wrong size or the display is the wrong color:
a. Check whether the monitor is a color or monochrome monitor.
b. Verify the video cable is properly inserted in the connector on the back of the computer.
c. Check for bent pins on the connectors.
15. If the customer has installed a video board instead of using the built-in video, make sure all
jumpers and switches are set properly on the installed video board. (See the manual for the
video board.)
16. If the monitor displays a badly scrambled image that looks to be the current screen image, then
the monitor is not synchronizing correctly.
If a video board is installed, replace it with a known good one. The video timing setting on
◊ ◊ ◊ ◊
the board may be bad.
If it is the on-board video, replace the system board.
◊ ◊ ◊ ◊
17. If a video board is installed and the built-in video is used:
a. Make sure the video board/built-in video combination is supported. Usually, two video
systems (for example, internal video and a video adapter board) cannot be used at the same
time.
b. If there is still a problem, make sure the board is seated correctly.
c. If there is still a problem, remove the video adapter board, and enable the internal video
system. Verify the problem.
18. If a message appears such as "INVALID CONFIGURATION", run the Setup Utility and press
[F2] during the boot process or boot the HP Navigator CD-ROM) to confirm the Netserver video
configuration. Make sure other accessory boards do not use the same memory addresses as
the HP video system.
19. If the problem is isolated to the built-in video system, replace the system board.
20. Once a suspect part has been found, verify it is the problem by reinstalling the part and
duplicating the error.

Configuration Problems

Symptom:
• An installed driver cannot find a PCI board
Installing a PCI board which bridges the two system PCI buses (certain adapter boards provide this feature)
can cause previously installed PCI drivers to not recognize their adapter board(s).
To resolve the configuration problem, move the PCI board that has bridging capability to a primary PCI slot.
