Is the monitor connector VGA by any chance? Check that none of the pins where you plug the cable into the PC are bent. If none are bent, ensure the graphics card is seated correctly. Loose graphics cards can cause garbled display. Try unplug the graphics card, unseat from the motherboard and re-seat.

M93p suddenly the screen goes black screen


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck

When I power on my I-Inc Ic194D, the blue does come on, after 1 or 2 secs, the screen will blink with white light and it will blink every other 1 or 2 secs. Nothing shows up. Can someone help?


Make sure the DVI or VGA cable is securely plugged into both the computer and monitor. If this doesn't work, try plugging the monitor into another computer. If it works when attached to a different computer, then the issue lies with the computer and not the monitor.
Good luck. Please rate if this was helpful.

My monitor, keeps saying it is going to sleep. VGA says no input signal, as well as DVI. And I know nothing about computers


If there is no output on the screen, check all you cables and connections and ensure they are snug and secure. If there is still a problem, it is possible your video card is to blame. As a diagnostic step, try hooking the monitor up to a different computer. Or hooking up another monitor to your computer. This will help eliminate bad cables and connections. If a different computer works on your monitor, then you most likely have a bad video card. If you monitor still will not work on any computer, then you most likely have a bad monitor.

Nothing on screen after turning on


Connect the LCD to a different (laptop? desktop?) computer, to see if the screen works at all.

Connect a different monitor to your desktop computer, to see if the video-card on your computer is working at all.
