    Sweetmedium1, post the Product Number of the HP laptop. This is in a white Service Tag on the bottom of the laptop. P/N = Product Number. Is it one of the Pavilion dv2000 series, or Pavilion dv6000 series, or Pavilion dv9000 series? Just wondering because there is an issue with these series, with inadequate cooling for the graphics chipset. Graphics chipset repeatedly overheats, and the BGA surface mount, that mounts the graphics chipset to the motherboard, develops 'Cold Solder Joints'. There IS a solution, however. Post back in a Comment. Regards, joecoolvette

Reball the chipset. Have it done in professional service. Ask for warranty for this repair.

    No need to reball the GPU. The solder balls are still there. But of course you know this, right?..............

    I think this is better. From my experience this works better and keeps same simptoms to appear again. Sometimes it's just the way it is, some models have a problem with overheating and it will crash again. Mate I got your point. I am new here and I just wanted to help around. I will be more accurate in my solutions in the future. I will also check the time when questions were asked ;)

    I think you are EXCELLENT Claudiu! Check what I stated in other solution.......I respectively disagree, but I hope we can agree to disagree, lol!........Even after re-balling the problem will occur again......This, as we both know, is due to inadequate cooling for the graphics chipset (GPU).........Surface area of small metal plate on Cooling Tube, is too small.........Correction is to not only re-flow the solder connections, but to add more surface area for cooling, for the graphics chipset........This is one idea I agree with for adding surface area.......Do NOT agree with re-flowing method. (Posted in a Comment once. He stated he agreed with me........Using an SMD/BGA Rework Station is the best method......IMHO the ONLY method, unless you want temporary results.......One week, one month, on year.........Rework Station? D-O-N-E........add surface area.........Only go back in to clean, or replace Thermal Paste, in the future)...http://www.youtube.com/watch?v=JEpnqhRYG... .............Nope.......This is the way I ride........Scroll down, click on the Red - Take a few minutes to view the IR 650 demo video........(No, I do not own one........he says with a glisten in his eye.......bahahahahaha!)

PC SWITCHS ON BUT NO PICTURE


1. Check to make sure your monitor is on! Some monitors have more than one power button or switch - check to make sure they're all switched on.Check for disconnected monitor power cable connections. Your monitor might be working fine and your only problem may be a loose or unplugged monitor power cable.Note: A disconnected monitor power cable could be the cause of your problem if your monitor's power light is completely off.Check for disconnected monitor data cable connections. Again, your monitor might be turning on without a problem but no information can get to it because the cable that connects your monitor to your computer is disconnected or loose.Note: A disconnected monitor data cable could be the cause of your problem if your monitor's power light is on but is amber or yellow instead of green.Turn the monitor's brightness and contrast settings completely up. Your monitor might be showing information but you just can't see it because these display settings are too dark.Note: Most monitors today have a single onscreen interface for all settings, including brightness and contrast. If it turns out that your monitor isn't working at all then you'll likely not have access to this interface. An older monitor might have manual knobs for adjusting these settings.Test that your computer is working correctly by connecting a different monitor that you are certain is working properly to your PC. Your monitor may be working fine but your computer might not be sending information to it.If the new monitor you connected does not show anything either, proceed to Step 6.If the new monitor you connected does show information from your computer, proceed to Step 7.Important: When testing with the new monitor, make sure you use the data cable that came with it and not the one from your original monitor.Determine why your computer isn't sending information to your monitor. Since neither monitor works, you now know that the computer is not sending information to the monitor. In other words, you've proven that your computer is the reason that nothing shows up on your monitor.Chances are your original monitor is working fine.Test your original monitor with a monitor data cable that you know is working. It's possible that the monitor itself is working properly but it can't receive information from the computer because the cable that connects the monitor to the PC is no longer working.Note: If possible, test using the data cable from the monitor that you successfully tested with in Step 5. If not, purchase a replacement monitor data cable to test with.Note: The data cable on some older monitors are permanently connected to the monitor and are not replaceable. In these cases, you'll have to skip this step and proceed to Step 8 Replace the monitor.

My pc does not give display ? Why


Time Required: Testing a monitor could take from a few minutes to much longer depending on the cause of the problem Here's How:
  1. Check to make sure your monitor is on! Some monitors have more than one power button or switch - check to make sure they're all switched on.
  2. Check for disconnected monitor power cable connections. Your monitor might be working fine and your only problem may be a loose or unplugged monitor power cable. Note: A disconnected monitor power cable could be the cause of your problem if your monitor's power light is completely off.
  3. Check for disconnected monitor data cable connections. Again, your monitor might be turning on without a problem but no information can get to it because the cable that connects your monitor to your computer is disconnected or loose.
    Note: A disconnected monitor data cable could be the cause of your problem if your monitor's power light is on but is amber or yellow instead of green.
  4. Turn the monitor's brightness and contrast settings completely up. Your monitor might be showing information but you just can't see it because these display settings are too dark.
    Note: Most monitors today have a single onscreen interface for all settings, including brightness and contrast. If it turns out that your monitor isn't working at all then you'll likely not have access to this interface. An older monitor might have manual knobs for adjusting these settings.
  5. Test that your computer is working correctly by connecting a different monitor that you are certain is working properly to your PC. Your monitor may be working fine but your computer might not be sending information to it.
    • If the new monitor you connected does not show anything either, proceed to Step 6.
    • If the new monitor you connected does show information from your computer, proceed to Step 7.
    Important: When testing with the new monitor, make sure you use the data cable that came with it and not the one from your original monitor.
  6. Determine why your computer isn't sending information to your monitor. Since neither monitor works, you now know that the computer is not sending information to the monitor. In other words, you've proven that your computer is the reason that nothing shows up on your monitor.
    Chances are your original monitor is working fine.

    Note: If possible, test using the data cable from the monitor that you successfully tested with in Step 5. If not, purchase a replacement monitor data cable to test with.
    Note: The data cable on some older monitors are permanently connected to the monitor and are not replaceable. In these cases, you'll have to skip this step and proceed to Step 8.
  8. Replace the monitor.
    WARNING: A computer monitor is not a user serviceable device. In other words - do not open the monitor and attempt to repair it yourself. If you would rather have your dead monitor serviced instead of replaced then please let a professional do it.

When I turn my monitor on, the screen shows the desktop momentarily and then goes black. If I turn it off and on a couple more times, the desktop will stay on and function normally. Where is the likely...


Try the monitor on another computer, to check-out the monitor.

Does the POWER lamp on the monitor stay on when the monitor goes black? If so, then the monitor probably is OK.

Try a different monitor, to trouble-shoot the video-card.

E176FP 17" LCD Monitor: my computer will come on but the monitor won't...


Here is what you need to do to know if your monitor is defective. Plug the power cord of the monitor. Turn on the monitor. If the monitor display image for a second and then black out then the monitor is OK. If not you will need to replace it.
If the monitor is OK.. look for other possible problem. Next to it aside from checking the cable (connecting your video card to the monitor) the one to check is the video card.. the signal from the cpu will pass through the video card to your monitor. If no reaction to the monitor then its the video card.

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 JUST CONNECT A SECOND MONITOR TO MY EXISTING RADEON 7500. I ALREADY SETUP THE 2ND MONITOR ON THE DISPLAY PROPERTIES ( WINDOWS XP) I CAN SEE THE MOUSE MOVING FROM ONE MONITOR TO THE OTHER, DOES ANYBODY...


    you'll have to drag them windowed to your 2nd monitor. Windows automatically will use your primary monitor unless you use software to control where which programs will load.

    A good program to use is called Ultramon.

    HP desktop monitor problem


    hi try this ,,,
    1. Ensure the video cable is connected (and connected to the correct video port).
    2. Turn off the monitor using the monitor's power button and then restart the monitor.
    3. Cycle the power on the monitor as follows:
    4. Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
    5. Unplug the power cord.
    6. Wait 5 seconds.
    7. Plug in the power cord.
    8. 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
      3. 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.
        hope it will work for u .. little_angel
