Message on monitor screen= "No Connection - Connect Signal Cable"
After turning off the computer and cleaning out the dust in the CPU, we reconnected everything and now the monitor is giving us the above message. We cannot find our manual. What do we need to do to get the monitor up and running again? We would like to use it in digital mode. Thanks.

Re: Message on monitor screen= "No Connection - Connect...
This message is pretty standard and translates into: "I'm fine but your cable or video card isn't."
You may have dislodged the video card while cleaning or possibly bent one of the fine pins of the video connector.
Check the seating of the video card, pulling it up slightly and pushing fimly back into the slot (sometimes the contacts aren't contacting) and then the video output connector.
Pull the latter and examine it carefully for bent pins, not missing ones since not all pin positions are used and those may be empty.

Can you observe any LED lights on the monitor panel when you try to turn it on. If no then check your power cables. If you can see the LED lights but screen does not show try to unplug the VGA/HDMI cable and clean it by blowing air through the plug and then reconnect it. Also try to turn on the monitor without connecting it to the monitor as this will verify if the monitor is OK because if it is it should display a message to check the input signal or no input signal is detected. If it does and you are still not having a display then the problem is probably in your CPU and more specifically in the VGA card.
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
disconnect signal cable if monitor show massage no signal check signal cable then monitor is ok then open cpu check whether dust is in ram then clean the dust and again fit the ram the problem will be solved if not then disconnect ram listen beep and if contineus beep comes then motherboard is ok if no beep then motherboard is faulty replace it
You first take post( power on self test) connect power cord & disconnect signal cable you will see massage no signal check siganl cable then problem will be in cpu this problem may be solved by cleaning dust in cpu if montor shows no display then problem will in monitor open it check o/p of smps if not disolder path of eht if o/p comes then eht is faulty replace it
Take the post (power on self test) disconnect vga cable and connect power cable if monitor shows no signal check signal cable massage then monitor is ok fault is in cpu. open it and clean the dust
by vaccum cleaner you will get the display again
hi, there is some loose contact in the connection. Take out the cable end from the VGA socket and check the pins inside the socket for any bend inside the socket. Reconnect it, tight the connector with the socket bolts. If not solved, try for any loose solder or wire breake.
If screen says "Signal cable not connected " all the time till power led switches to Amber chances are monitor is ok and problem is with graphic card or cpu.Connect to Known working CPU and confirm that monitor is the problem.
If same problem persists on another working cpu after changing signal cable,the interface board in the monitor could be defective.
This problem may arise from monitor as well as from cpu.
First of all check it by unplugging the VGA monitor cable.
This will display the "Check Signal Cable" depending on the model of the monitor. But a message will appear rolling on the screen, if it is not a very old monitor.
If the message is appearing OK and green light is continuously on, that means ur monitor is working fine.
The problem may be with VGA cable or with the booting of CPU and probably the RAM. Recommended solution is to reconnect the RAM and then try, if u think u can do. Otherwise call a hardware engineer.
If there is no message and still the light is turning green and yellow. That means the problem is definintely in the monitor.
