Re: monitor says no signal
This could be a multitude of things. Firstly, check the connections from your computer to your monitor, unplug them and plug them back in, make sure the thumb screws that connect your monitor to your computer and nice and tight but dont use a tool to tighten them, hand tight is good enough.
If that doesnt work, then check that your graphics car hasnt been unseated from its slot, TURN OFF THE POWER to your pc, open the case and look at the graphics card inside. Push it straight back against the slot and that might help.Try connecting the monitor to another computer, although I dont think its a monitor problem. or borrow a monitor from another computer and try it. If that doesnt help then you can try a different graphics card, if you dont have one they are readily available from most major electorincs stores, or even most supermarkets with an electronics dept. Now if you do all this and it doesnt fix it then you will need to find a tech to have a look at it, Like I said at the beggining it could be a multitude of sins, a hardware error stopping the computer from booting and that requires a little technical knowledge

In regards to your issue with your monitor: For a monitor to display "no signal input" there is likely a problem with the monitor making a connection to your input source (yes I know duh). First and easiest thing to fix this is to check your cables going between your computer and monitor, if your computer and monitor start out working and then fail to communicate, there is a good chance that the cable might be coming loose just enough that the connection fails. I might suggest that if you have, as you say another computer, that you try swapping monitors to check where the problem lies.
Is it a desktop computer? If it is, check the video cable in the back of the monitor, a blue video cable means analog input and a white video cable means it's a digital input. You may have a digital input and all you need is to press the button on the monitor that has a little monitor symbol and see if it switches input types. If you have the blue cable connected to the monitor and you still get no signal then you may have a bad video card.
Please check the cable that connects the monitor to the video card. Reseat the cable, the issue might be a loose connection. You can also try a known good monitor to isolate if it's the video card or monitor that is causing the problem. Something is preventing the monitor from receiving signals from the video card, hence the "no signal" message.
The monitor is telling you that it's NOT receiving a signal from the video card connected to your computer. Check the cable that goes from Monitor to Computer. Make sure it's secure. If it's secure, I would recommend you re-seating the video card, just make sure you remove power from the computer and you ground yourself. If you are not comfortable doing this, then I would recommend visiting a local mom and pop computer shop and have the technician take a quick look, should only take about 5 minutes for a decent tech to diagnose the cause.
Welcome to Fixya Support I am Michelle, and i will be assisting you regarding the issue
Please unplug and replug the monitor cable that connects to the cpu. a loose connection/ bent broken pins of the connector itself usually causes such an error message to come up.
Take a look at the back of the monitor there must be a cable which is connected at the back of your computer tower.
If you take a look at the back of your computer tower you will see that cable has a big plug with two screws on the top of it. It could be blue in color or may be grey. ( The name of that cable is Video cable )
Now what you have to do is to take that cable out of the computer. Now switch on the computer.
If you see a message on the screen saying " NO INPUT SIGNAL " :- That means your monitor is fine. If it does not shows that. Then your monitor is bad.
Remember the power cable of the monitor should be connected while doing the above steps.
Now incase you can see the "NO INPUT SIGNAL " message on the screen. Even then the problem persist.
It might be possible that the Video cable has gone bad. You need to consult a hardware technician for your monitor.
It is likely not a problem with the monitor, because the lights indicate that the monitor is turned on.
It may be a video card problem. Do you know if you have a video card, or if it is integrated graphics? Check all of the connections from the monitor to the computer. If you can connect the monitor to another computer and it works, then it is definitely your computer.
Very, very unlikely, but it could be that you're using a damaged cable. If you have another one on hand, try it. If not, don't go and buy one because this likely isn't the problem.
Another thing you could try is turning the computer off, unplugging the power cable (going to your computer), and hold the power button for about 30 seconds. Then plug it in again and power it up.
