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.

My samsung 940N acts like a florescent tube, tries to start and doesn't


Use the self test feature.. follow the steps..

1. Turn off both your computer and the monitor.
2. Unplug the video cable from the back of the computer.
3. Turn on the monitor.
If the monitor is functioning properly, you will see a box in the illustration below.
This box appears during normal operation if the video cable becomes disconnected or
damaged.
4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the
monitor.
If your monitor screen remains blank after using the previous procedure, check your video
controller and computer system; your monitor is functioning properly.

Warning

The Power supply inside the monitor can be hazardous and donot open the monitor while power on.

Donot work with the monitor when it is open and the power supply is on.

If there is something wrong with the input signal, a message appears on the screen or the
screen goes blank although the power indicator LED is still on. The message may indicate
that the monitor is out of scan range or that you need to check the signal cable.

Screen Goes Blank


Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

Blank screen - appears to be dead


If the screen is completely black, your screen may indeed be dead. There are a few solutions you can try before throwing in the towel though.

1) Test the monitor on another PC if you can.
2) Make sure the contrast, and brightness aren't turned all the way down.
3) Make sure the graphics card in your PC is functional. You can easily test this by connecting a known working monitor to your computer.

If these steps do not resolve the issue, and your graphics card is in good working order, you indeed have a dead monitor on your hands. It may be cheaper to buy a new monitor, than to have that one serviced.

Self-Test Feature Check (STFC) Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
  1. Turn off both your computer and the monitor.
  2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
  3. Turn on the monitor. The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
  4. Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Thanks
