    Have the same problem. When hooked up via DVI the monitor shows the bios and bootup screen and then says "no signal". I can mess with the power cord and get it to work but it will intermittently say no signal even when showing a signal. Just ordered new DVI dual link cables hopefully that solves the problem.

I had similar problem. I unplugged power cord to LCD, and re-plugged cord back. It solved the problem. Kind of cold-reset for LCD. I used DVI.

As I write to some other question:
Run your system in 'Safe Mode'. Go to Display settings and set lowest possible resolution. Then restart computer and run windows again in normal mode. Should have normal screen. If this will not work - then under safe mode uninstall graphic card. Then run windows with standard ones and in LOWEST possible resolution install drivers again. I have had it many times and it made swear first time.

Monitor no signal acer M1640


Check the cable at the back of the monitor and at the back of the computer. If the cables are in tight and you still get the no signal error message you either have a bad monitor or a bad video card in the computer.

Try plugging another monitor into the computer (borrow one from a friend, neighbor or family member if you don't have one). If the monitor does the same thing and shows a no signal message like your original monitor, then the Video Card in the computer is bad. If the monitors works, then your original monitor is bad.

I am currently on my laptop because when I turn on my desktop, the monitor (ViewSonic VX2235wm) powers on with a message that says No Signal Digital and then turns off. Any suggestions?


hi; your monitor has no problem, its your cpu. Try to hook your monitor to your laptop,and change the display setting to your LCD monitor. If LCD has displaying no signal mean signal coming form the Video card of your CPU try to visualize if you hearing some beeps into from CPU, some motherboard has beep codes if there's an error or failure to your CPU, 1 beep means its good system test. if you don't hear any beeps, try to check first your Video Card marmeto12_21.jpg if you have Spare try to replace it, try to reset all the connectors even Memory card to its slot. reset means pull the connectors and place it back again, also check the power supply of cpu if still functioning good.but you can test it by multi volt meter. if nothing happens check your motherboard most common failure is bloating capacitor, and overheating chipset. thanks....................hope this helps...................

The computer should beep ONCE when starting-up.
More than one BEEP implies either that the video-card is not responding, or that it is not fully "seated" in its slot.

Try a different video-card in your desktop.

It saids i have no signal


If your monitor says no signal, that means your computer video card is not putting out a signal to the monitor. Either that or you didn't turn the computer on.

Since you got the message, that means the monitor is probably good. You need to check the cables and the computer video output. Perhaps the video card has gone bad.

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 power on my pc,the monitor power indicator lights green but about 3s later it goes brown.the monitor screen remains unchanged as to when the computer was powered off.my email is...


You are not getting a video signal to the monitor. The fact that it is green initially shows it's working. When it turns orange, that's an indicator that it is getting no signal from the computer. So the next thing to check is if your computer is actually booting up or if your video card is going bad.
Do you normally hear a beep when the computer starts? Do you hear it now? If the answer is yes and no, then your computer is not starting up. To troubleshoot, I would suggest opening the case and disconnecting everything but the video, CPU, and memory. See if it starts. (you should get a message about no boot device if this happens)
If still no video, you have a hardware problem most probably related to the video card.

Signal has gone


If the monitor comes on and displays a message like "no input signal" or something similar, it's working properly but there is nothing coming from the computer. People often think that the computer is working and the monitor is at fault, when in fact the computer isn't starting up.

When you turn on the computer, do you hear the normal sounds of the power supply fan running and the hard drive spinning? Most computers will give a beep when they turn on and the motherboard finishes some startup checks. Do you hear that? Do you ever hear the normal startup sounds that mean Windows is actually running?

If you are convinced the computer is starting and booting into Windows, I would suggest you borrow a known good monitor to use as a test. If it works, that obviously means yours is bad. In most cases there's nothing you can do to repair a monitor yourself beyond checking for loose connections, bent pins in the signal cable plug, or a damaged cable.

If a known good monitor still has no image, the computer is at fault. Either the video card or integrated video isn't working, or the computer isn't actually starting up. In any case, that's where you would need to start looking for the cause.

Hope this helps you along the way to solving the problem. Thanks fo using Fixya!

When i turn my monitor on it is saying that no signal or cable is not connected but ihave evrything connected


The monitor will display that message until the computer starts and outputs a valid signal to the monitor.
If the computer is on and you still get that message, then you may have a bad video card/video circuit or a bad cable between the computer and monitor.

No display (black) - power light is amber color


The video signal is not reaching your monitor, check the pins on the connector from the monitor to the computer, then check the video card:

Turn off your computer, unplg the power, and then take out the video card. Wait 5 minutes and then put the card back into the computer and turn it on. For onboard video; turn off the computer, unplug the power, then hold down the power button on the front for 5-10 seconds, then plug back in and turn on.

Make sure the video card is snug in the AGP/PCI slot. If this is built-in video, try borrowing a video card from another computer and install it in this one. If the borrowed card works, then replace you card. If video is built in, then you can disble the onboard video and use the new card without having to replace your motherboard.

No any video signal from the video card


When you power on your computer do you hear any system beeps from the PC speaker? When the computer is turned on it will run through a system check and one of the things it checks for is the presence of a working video card. One beep typically means everything checked out ok and your graphics card is working and it will continue to boot. If you are getting past that initial test I would next look at the monitor and see if it can handle the signal that is being sent to it. Are you not getting any of the boot up text display?
