SOURCE: CHECK SIGNAL CABLE

Typically this happens when the resolution of the display is out of range of the monitor. Normally this is when the resolution is too high. Have you changed the resolution settings? Also, not to be crass, but if there a video card in the system, be sure that you are connected to the correct VGA connector. With an extra card in the system, the onboard VGA connector is not used.

Keep us posted,
Dan

SOURCE: Just acquired a TCO 99 monitor but the DC12v 3.0A

brucemeyer, Are you missing the Whole "lay on the floor black box switch mode power supply" thing, and not just "a cable"? Gee, those monitors aren't very good without their DC voltage source!!
You could always use a car battery, but then all you need to do is figure out where positive and negative plugs into the monitor. Remember This IF you get it Wrong, you could DESTROY the monitor forever!!!! The best bet for you will be to contact Taxan service and get a recommended substitute SMPS brick supply. Hmmm???? I wonder where the original went? I'm louie12fix on fixya or lmistyrel@ aol.com
Bye for now.

SOURCE: monitor says: no signal input check video cable .

Sounds a bit bland but either the monitor has failed or the video card

Only test is to plug your monitor into another system and see if it comes to life

If it does then your video card has expired.

If it is part of the motherboard then the easiest option is to buy a replacement which plugs into the AGP slot

They are dirt cheap unless you are into gaming when the sky's the limit

SOURCE: check signal cable

Check if the monitor is not working by connecting this monitor to another computer.

If the monitor woks on another pc, then the pc is the issue and not the monitor.

If monitor doesnt work on the other pc, then it's the monitor that needs replacing.

I hope this helps you :)

Power went off no monitor is giving check cable error


If you're seeing a "Check Cable" message on the monitor - it's working. If this message appears, it means the monitor isn't receiving a signal from the computer. Cable could be loose, or video circuit has failed.

How to repair lg flatron monitor tco fail problem & no signal


Have you tried plugging in your monitor to a different system unit? If by doing this solves yourproblem, then i would assume a graphicscardproblem, or maybe a contactproblemof it to the main board. Then, you can trycleaningthe graphiccardcontact. If this didn't work, you probably have a faultycard. Or you may try plugging in a known good monitor to your system unit? If after doing so resolves theproblem, then theproblemis on the monitor. Signal cables of monitors are the common cause of it, you may try movingthe cablewhile connected to your pc. Replacethe cableif possible.

When my computer says check signal cable what does it mean?


Your monitor is telling you that it thinks it is not receiving a video signal from the computer. You need to verify which of three components is not working, the computer, the cable, or the monitor.

The first thing to do, obviously, is to check that the cable connecting the computer to monitor is good. You will need some extra components to do the checking. I'm going to assume that the cable is detachable at both ends.
First you can try replacing the cable with different one. If the replacement cable works, then it's the cable.
Secondly, you can try different monitor. If you connect this in place of the first monitor, and it works, it's a faulty monitor (needs repairing or replacing).
Third try a different computer with the original cable and monitor, if it all works it looks like the video on your PC has malfunctioned. (This might also be your conclusion if a system comprising a different cable and monitor fails to work with the original PC)
You might just be able to verify the cable by testing the connectivity of all the wires in the cable with a meter, if you knew the pin out of the cable at both ends.
If you find out the computer is getting a signal out, there could be many causes for that, each having its own solution (or not as the case may be)

My 61in rca scenium is saying unuseable signal and there is no sound or picture


For whichever input the monitor is currently set to (i.e. Input 1, HDMI 2, etc.) it is telling you that the signal it is receiving is unusable. The question first is the monitor set to the input you truly wish to use?

If it is, then check the cabling between the monitor and the source device (cable/satellite box, game box, etc.) If you believe it the source is working, try swapping the cable or using a different input.

If that fails, try hooking up the source to another monitor and seeing if it works there. If you have a long cable run, try higher quality cables, the video signal can degrade over long runs (> 25').

It sounds like the monitor is receive *a* signal, just not one with enough data to be useable. Probably a bad cable.

Monitor is OK but when turned on the screen is black with a little square that has a message "Dell, No input signal". How can you repair this.


Monitor is not getting signal - picture from pc. Did this ever work or is this new pc? Is PC running? Does it do more than just blow fans? Like hard drive spinning up etc.. Check your video cable connections. Turn off monitor and pc first. Remove and re plug both ends of the video cable. Look for bent pins in plug ends before re pluging. Try a different cable if possible. If not fixed, you may need a new video card. Is this a pc that was working and suddenly failed? Either the pc is not running, or the video card is failed.

Princeton vl 1918 monitor on screen it says check cable no signal. how do you obtain signal?


You need to verify to find out if it is the monitor is bad or the PC is not sending the video signal to the monitor. Try another monitor with the PC, if you still have the problem then you need to fix the PC, if it works OK then it is the monitor problem.

Signal cable not connected


what do you mean? You are getting that message when you switch on? Have you checked the signal cable between your PC and your monitor? If you cable is connected properly and you are still getting that onscreen message, it means your monitor main board has failed, and if its out of warranty, its time to get a new one, because few repair shops will touch them, and when they do, it is not cheap.
