How do you fix no signal message on monitor?

Answer 1

It sounds like the cable has become loose. Try plugging it back in. If that doesn't help, then the cable itself may have become faulty, it may need to be replaced. Another possibility is the video card may have worn out and needs to be replaced. Another possibilty is that a button on the monitor may have been accidently pressed.

Answer 2

• Check (exchange) your VGA cable.
• Check the output mode

(on a laptop Ctrl + F8 is the standard way to cycle through outputs from internal screen to external output and or both)

Answer 3

This means that the monitor is not detecting any video signal coming from the computer. This can be caused by a number of things such as a loose cable, bad video port on either the monitor or the computer motherboard (or discrete video card), bad video cable, the computer is turned off, the video port you are trying to use is disabled or otherwise not functional, etc. If you happen to be using a Keyboard/Video/Mouse (abbreviated to KVM) switch, then you could have the switch set to the wrong port to see the video output of the computer in question. You might also have the monitor set to look for video from the computer on the wrong cable (for example, you are using a DVI cable between the computer and the monitor but you have selected VGA as the input source that the monitor expects).

If you are unsure how to verify each of these factors, get in touch with a local computer repair service and see if they can provide you some assistance. If you happen to be in the northeast Kansas area, feel free to drop me a line and I will be glad to have my store provide you assistance.
