Check your battery in your computer, it should read 3Volts, if it don't you need to replace it. If it is fine, then your monitor don't work.

Can i upgrade my old monitor to a new acer 19" Acer Monitor


Hi Ricky,
In most situations you won't need any special connections, as most LCD screens have the same VGA interface sockets and cables as your older screen.
Let me know if I can be of any further assistance.
Best wishes,

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.

Will my hp pavilion a 420n support a 19" flat screen monitor


Hello,

I have to assume you are currently using the larger size called a tube type monitor and would like to have an LCD or flat screen type monitor connected to your computer.

To connect to new LCD flat screen monitor to your computer would be exactly the same connection as what you are currently using.

The only problem you could run into is the connector itself. Some of the flat screen LCD monitors do not have the older style connector called VGA, usually blue called DB15, because it has 15 pin connector. They may have only have the newer style called a DVI type. Some do have both types.

Please be sure the LCD you want has the older style DB15 connector to connect to the rear blue VGA input of your compter.

Good Luck

M5640 power comes on no video. changed motherboard and power supply


I assume you are using the integrated video, (on board). With a new power supply and motherboard you have eliminated all but the monitor. Try a different monitor. I have also seen a case where a computer tower worked fine in one setup with a flat screen, but when hooked up to an older CRT monitor it would not display because of the resolution settings.

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.
  7. 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.
  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.

Display problem with Dell Inspiron 537


If it displays nothing at all through the boot process it's either the cable or the VGA card. It may be that the computer has gone into hibernate as it was left on overnight. Try pressing and holding the powerr button.

24" DOA Soyo Monitor


What size monitor were you using before? If you were using a smaller monitor and everything was fine maybe this new monitor is out of range for the graphics card. I've found that not all graphics cards, especially older ones, will not run a monitor as large as 24 inches. If you can, connect this new 24 inch monitor to a computer with a more powerful graphics card. If it works then you will know that the problem is with your computer. Also connect your old monitor and go into control panel and see what range and resolution your graphics card will support. You may need a more powerful card to run the new monitor.
