No monitor display


First,shut down the laptop.
take out the battery and plug the laptop into the ac adapter only (no battery).
turn on the laptop.
If it boots up fine then your battery may be low, or needs charging.
if still no picture, your display may have hardware problem.

if you have a separate computer monitor lying around the house, use the video cable from that monitor and plug it into the laptop video port (usually blue or black in color) - you will see where it fits in, about the width of a quarter and flat looking. Turn the laptop on with that plugged in and see if the monitor gets any picture. give it about 10 seconds. if not, you may need to press a key combination on your laptop (usually the Fn button along with F8 or one of the "F" buttons) that will switch between your your laptop and the LCD monitor.

If it works on the monitor, your laptop LCD is defective.

If still facing same problem then, your laptop has a video card/motherboard hardware problem.

Rgb connection stopped working on laptop


Instructions
    • 1 Decide if you want to watch the television on your computer or use the TV as a larger monitor. If you want to view the contents of the TV on your laptop, you need a video card connected to to the computer. These cards can either be inserted through the express PCI card slot on the laptop, or via USB cable. Make sure the video tuner card supports component video.
    • 2 Connect the DVI-to-component cable into the DVI port if you want to use the TV as a large monitor for your laptop. However, if you have a VGA port, plug the VGA-to-component cable into the VGA port.
    • 3 Plug the RGB component cables into the component side of the DVI- or VGA-to-component cable. If you want to watch the TV on your computer, insert the RGB cables into the TV video card.
    • 4 Plug the other end of the RGB component cables into the TV. If you are using the TV as a monitor, plug the cables into the "Component In" ports. However, if you are sending the TV signal to the computer, plug the cables into the "Component Out" port (the other end of the DVI- or VGA-to-component cable that you connected to your computer in Step 2).
    • 5 Power on the TV. If you are using the TV as a computer monitor, press the "Video" button until "Component Video" appears on the screen. If you are watching TV on your computer, launch the television viewing software that came with the TV tuner card. You can now see the contents of the TV on your computer.

How do i connect compaq presario x1000 to external monitor


Hi Judy,

The Compaq Presario x1000 notebook offers connections for external displays at the rear below the screen hinge as show in the picture below:

steve_con_5.gif

Identifying the back from left to right: Ventilation slots, External VGA Port, S-Video Port, USB Port, USB Port, RJ-45 Network Jack, RJ-11 Telephone Jack, Parallel Printer Port, USB Port and 1394 (a.k.a. "Firewire") Port.

You can connect a VGA monitor to the VGA port (blue colored jack) very easily. Any analog VGA monitor should readily connect to it. Additionally, the x1000 can output its display to TV or other monitor that accepts "S-Video" signals. An "S-Video" cable will be needed to connect between the "S-Video" jacks on the notebook (next to the VGA Port) and one on the TV. It is important to note that not all TVs support both or either "S-Video" or VGA inputs. When ever the there is a choice of using S-Video or VGA on a TV or monitor, the VGA will provide the best looking picture, and should be used.

I hope this helps and good luck! Please rate my reply - thanks.

Hi

I'm not sure what you mean by VGI. I will assume you mean VGA (Analogue - D Shaped with 15 pinholes).

When pixels or line of lixels fail on a monitor, they usually fail in spots or in a vertical lines due to the design of the matrix.

Since both monitors are sharing a single cable and the graphics card is a new one, the fault automatically isolates itself to either the monitor or its VGA connector.

Check that none of the pins in the end that connects to the faulty monitor are bent and/or touching one another and shorting.

Then try changing the resolution of the graphics card itself and test the monitor's performance at various settings to see if the resolution seeting is straining against the limits of the monitors range.

Right click on open space in the desktop > properties > settings > click and hold the slider scale step by step, up and down the scaled to test the monitor > apply > ok > test for a reasonable period > reset.

Also test the monitor with a single VGA cable to another computer (even a laptop, using the Fn key + external monitor function key).

Thses tests should tell you if the monitor is failing.

I hope this helps.

No signal or network problem


Connect the monitor to another computer if possible to eliminate the monitor as the faulty hardware
Shut down the computer. Remove all cables and devices plugged into the computer. Make a note of the port into which your monitor is plugged
Remove the left side panel when facing the front of the case. Unscrew screws or manipulate latches to remove the side panel. This process varies according to the type of case you have. Please consult your manual if you are unsure of how to remove the side panel.
Attach the antistatic wrist bracelet's clip to a metal object, then ******** the bracelet.
Locate your video card. (This will be the card that contains the port with which your monitor interfaces.) Remove the slot cover screw that secures the card into the slot.
Remove any power cables that connect the video card to the power supply.
Pull the card out of the slot. Examine the gold pins to check for any damage. Reseat the card if it physically appears to be undamaged. You should hear a click once the card is secure in the slot
Screw in the slot cover screw. Attach the power cable from the power supply unit, if applicable.
Leave the case open for now. Reconnect only the monitor, power cable and any devices required to boot the computer, then restart the computer.
Shut down the computer again if you receive the "No-input Signal" error message again. Remove any cables and devices you plugged in to restart the machine.
Remove the video card with a spare or replacement by following the instructions above.
Connect necessary cables and devices to reboot the computer, then restart it.
Shut down the computer and remove cables and devices if the display still won't work.
Unplug the power supply's cables from all devices on the motherboard. Make a note of each plug-in so that you can correctly connect all devices with the new power supply.
Remove the screws that mount the power supply. Fit the new power supply into the mounting area, and screw in all screws.
Attach all required power cables to devices connected to the motherboard.
Attach the cables and devices required to start the computer. Reboot.

First, make sure that the cable you are using is plugged in tightly on both ends...if some of the pin connections get loose the colors can go a little funky.

If Cable is tight try another cable. This will eliminate the cable as your problem.
If another cable gives you the same result it is then usually either a problem with the video card in your computer or the monitor itself.

Try plugging the monitor into another computer if you can. If the monitor is OK on another computer, the problem is then probably the video card on your computer. If you have a desktop, it can be replaced usually, or another video card can be added and used if your video card is built into the motherboard.

If all of those fails, it is likely the monitor went bad. Check if it is under warranty to see if they will replace or repair. If not under warranty you may want to replace the monitor at that point.

My Lg Monitor wont show screen (Power Button Flashing)


The monitor is probably on protection.

To start unplug monitor from power and from computer and test computer with different monitor to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

  • Video cable.
  • Video adapter on PC (sometimes integrated on motherboard)
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occur are a blown capacitor on power board, faulty inverter board, faulty input board, or a fault on LCD Digital Controller board.

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

Dell C521 Where to connect monitor?


This means that you have an external video card (which is not outside the computer). This video card will be plugged into the motherboard. That message is saying that the port on the back of the computer that your monitor is plugged into is the wrong one. You need to look for another port on the back of the computer.

Here is a picture of a VGA port that you should use if you have a VGA cable to connect the monitor (Blue Ends).

Here is a picture of a DVI port that you should use if you have a DVI cable to connect the monitor (White Ends).
http://zedomax.com/blog/wp-content/uploads/2008/09/dvi.jpg

So depending on the cable and connections that are available on your computer and your monitor depends on what you have to use. I hope that wasn't too confusing. Let me know if you need more info.
