Questions and answers about computer monitors.
Question: My HP m8000e desktop computer with 2048MB RAM and 300GB hard drive, seems to have a serious problem I worry about. When I start my computer, the monitor goes blank for more than 60 seconds. Why is that?
Answer: This is a very common problem, it can be caused by more than one thing.
First, make sure your monitor power cord is plugged into a working grounded AC outlet. Power up the monitor and be sure the power light is on, indicating that the monitor is receiving power.
Second, Make sure the monitor is firmly connected to your computer.
If you have a KVM switch, make sure the switch is correctly set to your computer You might need to connect the monitor directly to your computer to make sure the KVM switch is not damaged.
Make sure the computer is not in power save mode by pressing any key on your keyboard. You can also try to reboot your computer by pressing reset or the power button on your computer for more than 4 seconds.
Make sure your video card has enought power and if it needs to be connected to your power supply. Please refer to your graphics card manual.
If you have more than one video card, or multiple monitor outputs, try to connect your monitor to a different output and wait a few seconds. If you are using hdmi or dvi, you might need to restart your computer manually a few times by pressing the power button on your computer to make it work.
Make sure all cards, memory, hard drive and all cables connected to them are seated firmly.
Try to reset your bios (this will erase all user defined bios settings and go
back to factory set defaults). Refer to your motherboard manual how to do this.
Question: I have a E173fp 17 inch flat panel LCD monitor from Dell. I think many of my friends have the same problem as I do with the exact same Dell flat panel as I have. When the system is switched on, the monitor lights up for a second and then it switches off immediately. But the green light is always on. I have rebooted the system, I have tried to remove the monitor cable and plug it back in. When I do this, the monitor turns off and on. I have tried to alter the power features, the resolution of the monitor, downloaded updated drivers from Dell and viewed Dells troubleshooting advice on the cd that came with the monitor. Nothing have been resolved and I still have a problem. I am lost. I need this monitor to work for me. What should I do?
Answer: The problem might be a fault detection circuit in most of the flat panel screens to
shut down the circuits if some problem occurs. One of the greatest things, which
cause this kind of problem, is imbalance in the inverter outputs. This kind of
imbalance in the Dell systems occurs due to the failure of bulbs. Also more
frequent failure of one of the inverter branch circuits paves way to such
problems. Apart from this bad solder connection, weak capacitors, blown fuses or
shorted transistors also can be the reason for this kind of crisis. Replacement
of these parts will be the better solution for this problem. Start to replace
the inverter circuit first, go with the replacement of the bulbs second and
video circuit last.
Question: My monitor, a Dell SE177FP sometimes displays a number of upright color lines. There are changes in the color of the vertical lines that appear as well. It changes into pink, greenish or black. Sometimes the image jumps and the image gets blurry. There are not any buttons to press on the monitor that will help, except the power button. I have tried to resolve the issue using a Dell troubleshooting wizard. That wizard displayed some images on the screen. But I could not see any of the images really, the color lines started to appear. I need to know where to go from here.
Answer: The issue you are having should be easily resolved. It does not sound like your LCD screen has turned bad or started to malfunction. You can check the monitor by connecting it to another computer. If the monitor does not appear to have any display problems then you most likely have an issue with your computer and need to troubleshoot it and not your monitor. If the monitor still does not display the image correctly, pull the VGA cable off your computer and check for any damaged or bent pins. If there is any damaged or bent pins, the display may not work very well. If the cable is damaged in any way, replace it and your problem should go away.
