Make sure your monitor cable is screwed in on both ends. It is possible that your cable was damaged during moving, check for bent or missing pins on both ends of the plug.

Dell 2407 Can't get rid of "No S-video input signal" message on screen. How do I get rid of this?


Your S-Video connection is referring to a round plug for a TV input signal. Most computers will not have this connection unless you have a TV based video card. If your using a TV 'monitor' as your computer's video device, their will either be a button on the monitor or your remote to allow you to choose the input signal. If you are using a VGA or HDMI or DVI cable as the connector between the two devices, most likely, the light is referring to one of these, as its video source. You will need to match the cable & monitor source detected to get a usable picture output.

Good luck.
Toby.

Monitor stopped working - says No signal


Hi Paul,

This problem is often the result of a loose video cable connection on the computer or an incorrect video signal selection. Most monitors use a cable with "VGA" connector on the end that mates to the computer video port. Other modern computers make use of an HDMI (like the ones used to connect a TV to a BluRay Disk player) or DVI connector instead - either way if it is loose you will get the same "No Signal" message on screen. Make sure these connectors are making good contact with the port on the computer by seating them fully (or better yet - remove and reinsert). In the case of the VGA connector, most have two screws to hold them in the port - you should make sure both are threaded all the way in. You do not need to crank them down, finger-tight is more than enough.

Many newer - flat screen types in particular - do not have the video cable permanently attached. Instead, they use the same cord and connector arrangement found on the computer. It is possible that the connector has become loosened on the monitor end - especially if the monitor is moved / adjusted frequently. You should check the connections at the rear of the monitor just as you checked at the computer, too.

When satisfied that the connections at the computer and monitor are good, check the monitor again. If the message is still present, the monitor may be able to select between an analog input and a digital input via a menu item accessible from the monitor. Check your monitor manual for instructions to change inputs if unsure. If you are using the "standard VGA cable" (the one with the two screws) you should select the analog input. If you're using an HDMI cable, you should select the digital input. If you're using an DVI connector the input may be either analog or digital. When making a change, wait 5 to 10 seconds between toggling between the analog / digital selections to allow the monitor to sync the signal for proper display.

If you're still unable to display the desktop, it is possible that that someone has changed the BIOS options to select a different video card (if more than one is installed) or that the cable is defective.

I hope this helps and good luck!

I have a synaps monitor model mt9bbk. The screan will go black and power led will flash.


Display Power management is being triggered because no input signal was detected. Verify that the video source is connected and on. (Computer, notebook, etc).
- Try another computer or laptop that you know is working properly.
- Do you see any change on the screen if the display cord is completely disconnected (often a "Test" or "Check Cable" message appears). - Inspect the signal cable from the monitor - worn? Any places where the cable was bent to an extremely small (acute) angle? (less than 75 degrees?) Try gently moving the cable around at either end and see if you get a partial signal on the screen (while connected to the computer). If you do, the signal cable is damaged, if possible replace it. try: www.monoprice.com

Screen will not stay on, getting message no input signal


The message input signal means no signal is being feed to the monitor.
Check the cable use to connect the monitor to the video card.. fix and secure the connection.
If the computer is reading and you know its working, check the video card.
Turn off the CPU disconnect the video card from the motherboard and reconnect.
Try to open your CPU and see if it reacts with your monitor. If nothing happens replace your video card

When i press the power button to turn off monitor, i get a power button lockout message. how do i unlock the power button


I did not see anything regarding to the Power locked out function, may be it's time to call HP. Please post back what you find out from HP.
I look at HP WEBSITE: http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01632269&tmp_track_link=ot_recdoc/c01643091/en_us/c01632269/loc:1&lc=en&dlc=en&cc=us&product=3770762


Locking OSD settings
When the OSD is locked, settings cannot be changed in the OSD menu. The OSD functionality is enabled or disabled by pressing the Menu button and holding it for 10 seconds. Upon disabling the OSD, an OSD Lock-out message is displayed for 10 seconds. When the OSD is locked and an OSD menu button is pressed, the OSD Lock-out message is displayed for an additional 10 seconds. When the OSD is locked, pressing the OSD menu button for 10 seconds unlocks the OSD and displays the main menu. Identifying monitor conditions
Special messages display on the monitor screen for the following monitor conditions:
  • Input Signal Out of Range : Indicates the monitor does not support the input signal because the resolution and/or refresh rate are set higher than the monitor supports. Recommended refresh rates are as follows:
    • For the w1858 monitor: 1366 x 768 @ 60 Hz.
    • For the w2338h monitor: 1920 x 1080 @ 60 Hz.
  • Monitor Going to Sleep : Indicates the screen display is entering a sleep mode.
  • Check Video Cable : Indicates a video input cable is not properly connected to the computer or monitor.
  • OSD Lock-out : When the OSD is locked, the warning message OSD Lock displays for 10 seconds.
  • No Input Signal : Indicates the monitor is not receiving a video signal from the computer on the monitor video input connector. Check whether the computer or input signal source is off or in the power-save mode.
  • Auto Adjustment in Progress : Indicates the auto-adjustment function is active and in process.

I show on monitor "no signal" Check Signal Cable


Check that the "data" cable between your computer and your monitor is tightly connected at each end.

Connect the VGA-output port from a laptop computer to the monitor, to see if the monitor works when connected to a different computer.

Connect a different monitor to the VGA-output port on your computer, to see if that monitor works.

Failing all the above, the video-card on your computer is the problem, and needs to be replaced.

NO SIGNAL INPUT - message


Hi Rick,
Most common cause of this error is when the video signal cables are knocked off rendering the connection from the monitor to the CPU loose. Turn off the PC and secure all connections. Have you had your computer moved or repaired where you need to remove connections? Some PCs have more than one video cards (video output) and you may have connected it in the wrong video port. You can isolate the problem further by connecting your CPU to a known working monitor (office, freind's, neighbor, 2nd home PC). The other way is to isolate the problem is to connect your problematic monitor to a known working PC and see if video will be displayed. If video is present, your CPU's video card has gone bad or the contacts are not seated properly in the slot. Best Regards
