The troubleshooting process determines where a problem exists and how to correct that problem. Hewlett-Packard monitors, like any other monitor, can go wrong for a multitude of reasons, any of which can cause calamity if you cannot see what your Computer is doing. Proper troubleshooting determines if the problem is major or minor as well as whether you should repair the problem or replace the monitor. Troubleshooting techniques differ based on the monitor's problem; the following is a general troubleshooting guideline that ranges from power problems to display issues.Troubleshoot the power connection. Using the monitor's original power cord, plug that same cord into a different outlet; check if the monitor powers on. If not, use a different power cord. If the monitor still has no power, it is not likely worth the cost to repair (unless it is still covered by Hewlett-Packard's warranty and can be repaired for free).
Troubleshoot the computer connection by connecting the monitor to the computer. If the monitor turns on but displays no image, use a different cable to make the same connection. If the monitor works with a different cable, the original cable is bad and needs to be disposed. If the monitor still does not work, the problem is in one of two places: the computer's video card or the monitor's backlight.
Connect the monitor to a different computer. If the monitor works with another computer, the problem is with the original computer's video card; if the monitor turns on but still has no display, the problem is in the monitor's backlight. This, like the instance in Step 1, is usually not worth the cost of repair unless it is covered by the HP warranty.
Troubleshoot any awkward or unbalanced colors. Use the menu button to access the color bars; adjust the red, green, and blue tints until the picture is clear. If the adjustment does not work, connect the monitor to another computer. If the monitor displays normally with another computer, the issue is in the original computer's monitor port or graphics card. If the monitor still displays odd colors on another computer, the screen is slowly malfunctioning. Again, this kind of repair is not worth its cost unless it is still covered by HP's warranty.
