Question about Dell Dimension 4600 PC Desktop

1 Answer

No video display

Video display started blinking, then went completely blank. Now, no image despite multiple reboots. Monitor works fine when connected to different computer using same cable. Replaced video card with new one but still no image on monitor. CPU seems to power up OK but cannot get any signal to the monitor. Diagnostic lights on back panel suggest possible video card failure (A and C yellow, B and D green) but new card does not make any difference.

If the video card is built into the motherboard then try starting in safe mode and reinstalling the drivers from scratch. Download the latest drivers from the dell website. Safe mode will reduce the resolution and use a generic VGA driver. If your video card is plugged into a PCI slot try unplugging the video card and using a different slot and going through the same process. If you are still not getting any output to your monitor and you are positive the monitor is fine then you may need a new video card. To be sure, if the video card isn't embedded to the mother board, you could take it out and try it in a different computer. Hope that helps.

Asus p5lp-le no display


If it seems like the computer completed the boot process but the screen is blank, try the steps below.

The problem will either be the monitor or the video card inside the computer. Connect another monitor to the computer to isolate the problem. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays and works ok, then your original monitor is bad and the video card is good. If the Borrowed monitor does not work then the video card inside the computer is bad.

If the computer did not complete the boot process then try the steps below.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the computer is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

I have an hp pavilion dv5. When I power it on the computer starts up but the monitor doesn't come on. And then it does this series of beeps. Beep beep beep. It does that series 5 times


Before you begin
Check the following items before using the steps in this document:
•If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
•Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
•If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
•Disconnect all connected devices except the mouse, keyboard and monitor. This includes thumb drives and camera-type memory cards from card reader slots.
With the devices disconnected, restart the computer. If the computer starts and the monitor now displays a picture, a device is preventing the computer from starting. Update the BIOS to resolve this issue.
Step 1: Connect the computer to another monitor
Connect another monitor to the computer to determine which device has the problem (the monitor or the computer). This step is very important to help you determine if the problem is coming from the computer or the monitor. If necessary, temporarily connect the computer to a friends monitor for troubleshooting purposes.
After the monitor is connected, turn on the computer and the monitor. What happens?
•If the newly attached monitor does not display anything , disconnect the cable and continue at Step 2: Is the video connection damaged?
•If the newly attached monitor displays the first startup screen(s) but then goes black, there is a problem with Windows starting. Skip to step 5 .
•If the new monitor works , the original monitor or its cables are faulty. Do the following:
1.Replace the monitor power cable.
1.Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.Replace the video cable.
Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.If the monitor does not work after replacing the cables, replace or service the monitor.
Step 2: Is the video connection damaged?
Inspect the video cable and video connectors for damage. Check for sharp bends or breaks in the cable and bent or broken pins at the connectors. With the monitor and computer off, try to straighten bent pins with a small metal tube, like the tip of an empty mechanical pencil or the tip of a retracted pen.
Figure 1: Video connector
If you had to straighten any pins, reconnect the monitor making sure that the video cable is firmly connected and then turn on the computer and monitor. If the display is still blank, continue to the next step.
Step 3: Resetting and updating the BIOS
You can use these steps even though you will not be able to see anything on the monitor.
In case an item was changed in the BIOS, such as the primary display device setting, use the following steps to reset the BIOS back to its default configuration:
1.Turn on the computer and repeatedly press one of the following keyboard keys. Press the key about once every second for 5 seconds after turning the computer on.
◦For HP and Compaq computers that came with Windows 7 and Vista, press F10 .
◦For HP and Compaq computers that came with Windows XP, press F1 .
◦For Compaq Presario desktop computers built prior to 2002, press F10 .
1.Wait another 5 seconds.
1.Press the F5 key. This restores the default settings of the BIOS.
1.Press the Enter key. This accepts the changes.
1.Press the F10 key. This saves the changes.
1.Press the Enter key. This saves the changes and exits from the BIOS.
1.The monitor should display the first screens received from the computer (the logo screens). If not, find and download the latest BIOS update if one is available for your computer.
1.If a BIOS update was not available or the monitor is still blank, continue to the next step.

Boot performance monitoring error


>> Tired to reboot several times and still no video.
>> Waited until the next day and the video was working.
>> Very strange.

Sounds like overheating, either inside the monitor, or on the video-card, or inside the computer.

When it happens again, disconnect the data-cable from monitor from the desktop computer, and connect the data-cable to a laptop computer.
If the monitor works, then it's not the monitor that is the problem.

Also, when it happens again, have another monitor, and connect it, to see if the other monitor works, or if the video-card cannot "drive" either monitor.

My monitor screen is ok for awhile but suddenly turns a dull yellow color. I just bought it a few months ago.


Hi,
you must adjust the display settings in the software program that was being used to change the display setting.
  • If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
  • Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
  • If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
  • follw the another steps-
  • Replace the monitor power cable.
    1. Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    2. Replace the video cable. Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
    3. If the monitor does not work after replacing the cables, replace or service the monitor

    I had the same problem same model. The image was off center to the right and it couldn't be fixed by the auto-image adjust or the manual adjust.

    My solution was really simple, I moved a video player (RealPlayer) onto the monitor and maximized the screen, then pressed auto-adjust once. It worked.

    NO SIGNAL What do I do?


    These messages are normal when the computer truly goes into suspend mode or loses the video signal (such as when the computer is suddenly turned off).
    If the monitor displays any of these messages when the computer should be displaying video , do the following items until an image from the computer appears:

    1.
    Ensure the computer is really sending a video signal. To bring the computer out of suspend mode: move the mouse, press the spacebar, and press the suspend button on the keyboard twice (the suspend button has an icon that looks like a quarter moon).
    2.
    Ensure the video cable is connected (and connected to the correct video port).
    3.
    If you are trying to view video from a set-top box, DVD player or similar device, use its menu system to set the proper video output channel so that it matches the video connection are using. For example, if the monitor is connected to a satellite receiver via a second HDMI connection on the back of the receiver, select HDMI-2 (or similar) using the remote control for the receiver.
    4.
    Turn off the monitor using the monitor's power button and then restart the monitor.
    5.
    Cycle the power on the monitor as follows:
    1.
    Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
    2.
    Unplug the power cord.
    3.
    Wait 5 seconds.
    4.
    Plug in the power cord.
    5.
    Press the power button on the monitor to turn on the monitor.
    One of two things happens:
    1.
    The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
    2.
    The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution.
    6.
    Adjust the Windows display resolution to a setting that is compatible with the monitor:
    NOTE: The native resolution setting for your model of monitor can be found in the Monitor User Guide, the monitor's product packaging, and product specifications.
    1.
    Restart the computer and press F8 repeatedly after the first logo screen.
    2.
    Select Safe Mode .
    3.
    Windows should open showing a Windows desktop with lower resolution and fewer colors.
    4.
    In Windows Vista, click Start , Control Panel , and click Adjust Screen Resolution in Appearance and Personalization.
    In Windows XP, click Start , Settings , Control Panel and then double-click the Display icon and select the Settings tab.
    5.
    Move the slider bar until the native resolution for the monitor is set, click OK and restart the computer.
    6.
    If the native resolution is not available from the slider bar, click Advanced Settings , click List All Modes (from the Adapter tab), select the resolution, and click OK .
    If the native resolution setting is not available as a selection in Windows, you can temporarily use 1024 x 768 to complete these steps. However, you should update the graphics driver on the computer. Updating the graphics driver can provide more display resolutions to Windows; possibly including the native display resolution for the monitor.
    *
    Check for nVidia video driver updates at nVidia Home Page (in English).
    *
    Check for ATI video driver updates at ATI Home Page (in English).
    *
    Check for S3 video driver updates at S3 Graphics Home Page (in English).
    *
    Check for Intel video support and downloads, Intel Downloads (in English).
    *
    If you own an HP or Compaq computer, HP hosts video drivers and some video driver updates at the HP Software and Drivers site (in English)
    7.
    Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
    *
    If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
    *
    If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
