Monitor won't turn on

My dell lcd monitor won't turn on. There are no lights. It's just dead. It worked fine until I moved, and had to disconnect everything.
I plugged in a different monitor which is working fine.
Is there anything I can do ?
Thanks for your help.

    Thanks for the responses. Dshack, unfortunately this monitor is well out of warranty.

Depending on when you bought the monitor, and the warranty...

I would suggest contacting Dell for an RMA. If you bought it in-store it's possible they will let you RMA it. Also, if it is something simpler, it may be worth taking it in to a computer repair store and letting them take ten minutes to look at it. Most will not charge to simply look at something - if it's something they can't figure out, and thus cannot repair, you will need to contact Dell.

I would start searching for the papers that came with your computer, specifically warranty papers.

Hello,

If there is no power indicator to the monitor, then maybe please verify the inside fuse, maybe got busted. else consult the nearest repair center.

You should be able to just press the main system unit power button to wake up your 'sleeping' computer which will then resume your Windows desktop and bring you back to the Login panel if you have a password set for your account.

Tip

Monitor LCD Screen Replacement With A Laptop Screen


This tip is for the typical PC tech with a shop full of dead laptops and monitors, looking to make an extra Monitor for bench testing malfunctioning PC's. Maybe you're a tinkerer and just have some spare parts laying around, and want to make something cool and easy. Either way, this tip is a fun way to make old dead parts work for you, rather than sitting in a corner gathering dust.

Replacing a Laptop screen is pretty easy if you take it slow.
LCD Monitor screens are actually easy to replace too, if you are careful not to crack anything getting one out and in again.

This tip doesn't address any of the typical replacement methods.
What this does is show you how to use a laptop screen in a standard Desktop LCD monitor.

Having already disassembled your Desktop monitor, and determining that one or both of your backlights is dead, you will most likely begin searching for sources of a new one. Before you do that, try testing both backlights in the dead monitor screen first by hooking them, one at a time to an inverter in a working laptop to verify that both are dead.

Most of the time, you will discover that only one light is dead, and this is where the fun begins.

At this point, you have a few choices to make.

1. Extract a working backlight from a cracked LCD, we all have a few of those lying around somewhere in just about any PC tech area.
2. With the extracted backlight in hand and the old LCD screen still attached to the monitors electronics, remove either of the sets of wires going to one of your backlights, leaving one still attached.
3. Now you can attach the light you extracted to the empty socket your original screens light attached to, while leaving the other one still attached.
4, Now, turn on the monitor and wait for the extracted backlight to come on, if it doesn't switch it with the other light socket plugged to your screen, and plug the opposite light wire back in.

This will do 2 things for you. First, it will be a quick test of your inverter, and second it will verify that you do or don't have at least one working backlight still functioning in your monitor.

Remember that with most LCD monitors, just one backlight can provide enough illumination for your screen to show a very crisp picture.
The problem appears though, when we decide that our existing LCD is dead because we dont see it light up.

The solution for this is to simply disconnect the dead light wire from the existing inverter plug leading to the LCD screen, then replacing that with a working light from the cracked screen without disassembling the LCD screen itself. If you did everything right, your old dead screen will be working as it should. Be sure you swap the backlight connecting wires so that your Bright/Dim controls work as they did before.

You see, most dual light inverters work the same as a standard twin tube household flourescent light. When one goes out, they both eventually stop working. So, adding that second light completes the circuit, then swapping light socket connectors turns your backup light tube into the primary light, instead of the secondary.

Now, if THAT trick didn't work, you can move on to the Laptop LCD trick, which is pretty much what you did before, except that the Laptop LCD usually only has 1 light tube. So for this to work, you can complete the lighting circuit by simply adding your spare backlight tube to the second open backlight connector, then installing the LCD to your monitor.

Many of these Laptop LCD screens are the same height and width as comparable Desktop screens, but they are also thinner, and will have to be glued or taped to the frame from the inside. Everything else connects exactly as the original screen, but may need to have wire added to the Laptop backlight wire so it reaches the power source.

I figured this tip was worth posting, since I just did this trick with a 15" polaroid HDTV/HDMI/HiDef Television/Monitor combo.
The model I have died a few months after it was bought new from Walmart, and the customer just didn't feel like paying $129 for a new screen.
Being the packrat I am, I just couldn't bear throwing it away, figuring that some day I would find a matching screen. As you can see, I got tired of waiting. The pictures of my project are below.

dc79966.jpg2e21d78.jpg

That bright line of light isn't the flash from my Camera, it's the flourescent light tube from a broken LCD screen placed on top of the steel housing.
The incidental effect of that light is that my back wall is a nice nitelite, and hooking up new components is a lot easier. Yes I could have blacked it out, but I think I like the added light behind the TV.

I hope this Tip comes in handy for you.

When i turn on computer only the power on light displays and nothing on the monitor. at first thought it was the mkonitor, but hookrd up to others and same prob. help please!


  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.
  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.

Orange lights on monitor buttons


unplug the monitor from the computer then turn on the monitor and check if theres any monitor self test. its like diff colors moving around the screen if you see those then it means your monitor is working fine.
check the video cable. try to use a known good video cable and if it worked then you have to check the video card.
or plug your monitor to a diff system.

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.

Dell computer monitor wont come on when I turn


When you turn on most dell monitors they come on with a yellow light, then turn green when the monitor and video source synch. If your light is not turning from yellow to green, your monitor is either dead or not getting a signal from the video source it's plugged into. Verify in your BIOS settings that you have selected to output video through an installed card and not from the motherboard source. If the BIOS settings are correct, your monitor has died. If the light is turning green after you turn the computer on, press the menu button on the monitor and adjust the brightness/contrast until you have a picture. If you don't see anything when the menu button is pressed, then again your monitor is likely dead.
