Check signal message when data cable unplugged. blank screen when data cable plugged

I was using this monitor fine before now when connected to my laptop the monitor doesn not display video (in monitor only mode, clone desktop mode and extended desktop mode). but if i unplug the data cable, the monitor displays the 'chech signal' message. the monitor menu buttons on the monitor (for changing contrast etc) don't work since this blank screen problem has started. the menu buttons don't work regardless of whether the data cable is plugged or not. please help! Thanks akabbob

    RE: i still have the same problem-depite fn-display command
    Thanks for your advice nfandres.
    I've tried doing that though. I don't think I made myself clear before. I only use this monitor as an external desktop on my laptop. It worked perfectly find before. I don't know why it doesn't work properly now. I know the various ways of activating external desktop (eg1) fn-display as you mentioned, or 2) sys tray> graphic icon> graphics options, or 3) Rclick desktop>properties>settings) These methods don't work anymore. the monitor doesn't even respond to activate it (ie as primary display, clone display, or extended desktop) ie that sound it usually makes when its activated. However if I unplug the data cable, and the 'check signal' box pops up on the monitor- that sound I just talked about happens. Wierd huh?.
    So if someone can help please do, so a poor guy can get his extended desktop back :(.
    PS i've tried connecting the data cable before booting, or before waking from standby/hinernation, or even when the latpop is running. But no avail.
    PPS the only difference to the monitor has been that I installed a montior shelf on top of it and placed my printer (not really that heavy that it is unsuitable for the monitor shelf). But it was operating okay after I did this. I'm certain of that.
    Any help would be much appreciated :)

    Help me. I am on my own here and I fianally get to use my desktop and try to get my desktop going again, I have not been on my tower for 6 weeks, I been using my lab top mostly when I was away, Now I am trying to hook everything and get to use my desktop again, I had my tower getting some service on it, meaning, power supply was replace. They told me that it is fine now. I came back to hook up my monitor to my tower and it is saying that there is (no signal....anolog....) I don't understand that, I recheck all my cords and it is fine. Can you please help me with this problem. I just get a blank screen but my tower has power.

    Thanks again.

    printerhater is correct. thanks friend.
    I connnected a different monitor (that i've already tested) to the laptop in question and it didn't work. Hence, the vga connector in the laptop is faulty.
    ps sorry about the poor rating initially, i don't know what happened.

This problem is most likely to be caused by a bent or broken pin on the CRT video cable at the VGA connector, OR, this could also be caused by a damaged VGA connector on the back of the laptop. If neither VGA connector is at fault, the problem could be caused a damaged (kinked) CRT data cable, or internal damage to the VGA connector on the back of the laptop, though I suspect the problem is more likely to be external, and you probably won't have to disassemble the laptop to locate the culprit...

    My advice here has been rated as "poor", which is absurd. Whether or not this advice solved the problem as described by akabbob, it is STILL valid advice, even if it did not apply to his particular problem. The fact is, broken and damaged pins within the VGA connector are USUALLY the cause of this type of problem, with a defective CRT data cable the next most likely culprit (I should know, I've been repairing CRTs since 1977, long before the arrival of the IBM PC)... the advice I posted is CORRECT, even if it didn't help akabbob. Clearly, he doesn't understand how the rating system works, but since this is the first time he has requested advice here, I guess I can't expect him to comprehend intelligent advice when it is presented to him... nfandres ALSO posted advice here, which did NOT solve akabbobs problem, but for some reason, akabbob rated that nfandres suggestion as Good, while mine was rated as Poor... since both postings are equally valid, the Poor rating I received is totally unjustified.

Is it an old monitor? Did you try plugging the monitor on another pc? Did you try plugging your laptop to another monitor that you know it works? The old monitor will just wearout. I keep old monitors and pc's around just for test purposes, so i don't have to test problem pc components on my main pc.

No signal to monitor

Check all conections between the tower and the screen, make sure all are secure, if no joy, unplug the tower and remove the side panel to see if the graphics card is in securely, maybe take the graphics card out and put it back in again to be sure. If you have another monitor or monitor cable try replacing to see if the situation improves.

Try another cable, or check the plug for bent pins. If they are all good, check that the monitor is set for VGA input (if it supports VGA and DVI) as it may be looking for a different input. Then replace the monitor. It's not common, but video processing circuitry can sometimes fail, and yours may have. New 17-inch LCD monitors are quite inexpensive now, so it would probably be more economical to replace this one than to try repairing it.

I have a samsung 17'' lcd monitor.when i power on my monitor without data cable i got a message on screen CHECK SIGNAL CABLE.when i connect data cable my lcd is going to power off.please help?

The message says that the monitor doesn't receives signal - which is normal. Since the problem appears only after you plug in the cable in means that the problem is located there - something is wrong with your pc, most likely the video card has died.

Power on - blank (black) screen

Disconnect the monitor signal cable from PC and switch on your monitor. It should show some logo with Red, Green and Blue colors with a message similar to "No signal". If so, your monitor is working fine. Sometimes if the brightness and contrast is set to zero using controls present in the monitor, it will not show up anything. check wheather somebody set your monitor brightness and contrast to zero. If so incease them. As a last try connect to different PC and check before approaching a service center. I hope this will help you out. :)
