Hi,

First, check the linecord /power connections to the display.
If they prove out OK, then check the video connections. You may find them loose. If that's OK too, then:

You can either connect a different monitor, or add the appropriate
connector/adapter and use a TV.

Regards,

M93p suddenly the screen goes black screen


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck

Dell backlight indicators


A computer monitor has a front-mounted LED that displays its current status and flashes in the event of an error. When an error occurs, the flashing may be accompanied by an error message on the screen. If the screen does not display an error message, the problem most likely falls into one of four common categories.

Unsupported Display Mode A video card has the ability to send output to the monitor at many display resolutions and refresh rates. However, no single monitor is capable of supporting every possible display mode. When the video card sends an unsupported display mode to the monitor, the monitor shuts off to prevent damage and blinks, or displays an error message. Standby Mode b> When a monitor detects no video signal from the computer, it assumes that you have turned the computer off and enters standby mode to reduce power consumption. Dell and HP monitors display an amber light when in standby mode. The status light on an Apple monitor blinks slowly. Incorrect Power Supply Some monitors such as certain Apple Cinema and Studio displays use external power adapters. Because different power adapters may have similar connectors, these monitors are designed to detect when an incorrect power supply is connected and blink the status LED rather than attempting to turn on. In the case of an Apple display, the LED blinks in an alternating short and long pattern. b> Backlight Failure b> A flat panel LCD display has an LED or fluorescent backlight that illuminates the pixels and makes it possible to see the contents of the screen. If the backlight fails and requires replacement, the monitor is unable to display any information. In some cases, you may be able to resolve this issue by turning the monitor and computer off, disconnecting and reseating all cables. If the monitor still has a backlight issue, it requires professional service.

When I turn my PC on you can hear it come on but the screen is black.


It sounds like you might have a problem with your video card. If you turn it on and see nothing, not even the gateway logo, than you either have a video card issue or a monitor issue. Hook up the mahine to another monitor to test.

Hello, i have a slim line s7700n and i have a problem. The screen wont turn on and it displays no input signal. I dont know if its the monitor or the computer?


1. You could have a faulty video graphic card on the mother board.
2. Your display or LCD screen has a bad power supply adapter or not get power at all.
3.Your display has a bad inverter board and needs service. I cannot tell not being able t o see the devices physically.
4. A computer tech can determine this with a few simple isolation test such as disabling the video card and using a know good one in the pci or AGP slot and connecting the monitor to it.
I hope this helps. Have a good day.

Tower turns on but nothing appears on monitor


You need to follow the easy steps and get rid of it

1. Make sure your display (moniter, CRT, LCD, screen, whatever you prefer to call it) is plugged into a wall outlet or power strip and powered on. Also ensure that it is securely plugged into the back or bottom of your display. Many displays do not have removable power cords, making them more prone to shorts and other damage. Check your cable to make sure it isn't damaged.
2. Make sure the power strip or wall outlet that your display is plugged into are functioning by plugging another electrical device, such as a lamp, into it and switching it on.
3. Check the connection between your computer and your display. Make sure that it is completely plugged into both as well as fastened with the attached screws.
5. To double-check any possible cable problems, if at all possible, swap out the screen's power cord and the cable connecting your computer to your display.
6. Swapping out your display is also a good way of narrowing down the problem. If you get the same result with a different display, then you can be near positive the problem is something in your computer. If switching displays fixes it, then the culprit is a faulty display.
7. Try turning your display on and off. Does the power indicator light change? Green means On, amber means Standby, and no light means no power. If your display starts out green when it is turned on, then goes to amber, that usually means that it is not receiving any signal from your computer and therefore assumes it is not needed. The problem is most likely not with the monitor but in the computer.

E-machine was working fine last night got up and it turns on but the monitor says check cable or power but all is ok.Computer wont display anything, can anyone help?


Do a reset: Turn the computer and monitor off. Unplug the monitor video cable from the computer and unplug the monitor power cord from the wall outlet. Let it sit for 5 or 10 minutes. Plug everything back in, turn on the monitor, then start the computer. Sometimes that will work.
If you still have the same problem, try to borrow a known to be good monitor from somebody. If it works, then you know your monitor is bad.
It's also possible that your video circuitry is bad. If the monitor plugs straight into the motherboard (onboard video), then you'll need to purchase a video card and install it. Disable the onboard video first.

Dell 2400 desktop


First, check your monitor, Is the power light on and amber?
If not , monitor is dead.

If monitor light is amber, Check the power supply fans and cpu fan. See if they are operating ok.

If monitor is coming on, fans are working, I would Pull out the adapter boards that are installed, then power on the unit. If the unit displays video, then reinstall adapters back in one at a time.
Make sure you power down when ever you remove/install anything in the PC.

Monitor does not come on, but system loads, thus I need to fix the monitor issue with the dos prompt, if possible, any answers


Sorry can't fix monitors with Dos prompts these days. Try another monitor that you know works. Make sure both plugs from the monitor are plugged into 1) wall / 2) video card on computer.
If still no monitor try a new video card.
