WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Test all power and data leads that attach to your hard drive IDE,SATA the leads from your (motherboard to your hard drive) make sure they have secure dust free connections and are not faulty if its a 40 pin flat ribbon type it will be the first to fail make sure all leads that are attached to your drives dvd\cd and floppy have secure connections and are not faulty even something as small as a faulty electrical fan and its lead can cause you problems computers need all power and data to continue through every working device and to have an end so any faulty leads will end up with a computer error Check your RAM. The RAM is located in the middle of the motherboard. There are tabs that you can push to release the RAM. Remove it and put it back in place until the tabs pop out. Loose RAM can cause your computer not to start properly where you want to see a video signal. Make sure your graphics card is securely seated with no dust built up or in the socket if you remove your graphics check the socket to make sure its dust free Restart your computer then reinstall it this should activate found new hardware wizard Check the vga lead for secure dust free connection or try another vga lead. also If you have used a desktop computer or have a dual-monitor setup, you have likely seen the "No-input Signal" error message on your computer monitor. The error message may point to a number of culprits. Accordingly, the solutions run from simple to complex. Prior to attempting advanced troubleshooting methods, check the connection first. Power off the computer and the monitor. Remove the cable that connects the monitor with the computer, then reseat it. Try a different port, if possible, then reboot the computer. 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. http://en.allexperts.com/q/PC-hardware-CPU-1023/input-signal.htm

Connect a different monitor and check if it shows the same thing. If it does, then I suggest that you update the driver. If it's not going to fix it, then you might want to have the video card replaced or resetted. It could also be a problem with the data cord. If you don't see the problem with the other monitor, then you would need to replace the current monitor that you are using.David

Probably a bad power supply or an exhausted backlight source, or both. You can pry apart the monitor shell and look at the power supply board for bulged capacitor(s). Just replace all the large ones if even one is bulged. You need soldering tools to do this job.

Sound like you lost one of your colors (red, green, or blue). You can try an autosync function on the monitor, if there is one, or autocolor adjust, or something similar. But it sounds like the monitor LCD panel might be defective beyond repair. Youn can check your color levels. SOmetimes one will drop to zero for no reason. Try running your finger (pushing lightly on the LCD) around the edge of the monitor screen. Sometimes a transistor just gets stuck and you can close it back up. Keep track of where your finger is when the picture is correct, and home in on the exact spot. Then, just massage that area with your finger until the display looks right. That doesn't always work, but it's worth a try.

CRT and LCD will look different when compared side by side. Is your CRT calibrated, or are they right in the sense that they are what you are used to? Also Anyway, you can adjust the colors and light levels from the menu on your screen, and depending on your operating system and graphics adapter you should be able to make adjustments there, too. For windows XP, right click your desktop and select properties->Settings->Advanced. There might be a color management tab. Also, there might be software to help you do this already installed. Look for a program group with the name of your Graphics adapter manufacturer. Very often ATI or nVidia.
