Re: no signal on monitor

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.

Re: no signal on monitor

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.

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...................

Asus led monitor model vh197 shows no signal on screen and no display ,screen became dark

Good Day Dasarathi!

Please check the VGA cable if its properly connected and make sure two screws are fixed to both end connecting the monitor and the video card.

No signal comes out when there is no signal from the video card to the monitor. That is why you need to check if the VGA cable is fix to both end.

If that did not fix it, you will need to open the casing of your computer. Disconnect the video card from the motherboard. Gently clean by wiping a clean clothe over the contact surface of the video card. Then, reseat the video card properly to the slot in the motherboard. Return the casing cover and connect the VGA cable again.

Just remember doing the above procedure is only when the computer is turn off.

Turn on your PC and see if that fix it.

You will need to replace the video card if by booting the PC you will hear a series of beep codes. If no beeps then you are lucky VGA cable is the faulty one.

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 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!

The monitor says ''NO SIGNAL'' All the tower lights are on and I can hear it satrting up. What should I do?

It is telling you that there is no video signal coming from the video card. Check to see if the cable from the computer to the monitor is tightly plugged in.
If it is and you still get no signal, I'm thinking your video card has gone bad.

Gateway FPD1760TFT LCD monitor

1. turn on computer
2. monitor receives signal, it looks like its working
3. it goes through some steps and then the monitor says "no signal" and kind of stays in limbo with fans running, etc.

One possibility is that computer is looking for drivers for you video card. It could be hung up looking in the wrong places. Remove all peripheral hard drives and memory sticks. Try again.

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.
