The screens starts to blink.


You're probably correct, but it could be the video card is set to the wrong resolution for the monitor. You should check that first. Monitors usually just pry apart, but the force required and the hideous cracking sounds deter many amateur would-be monitor techs.

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

Everytime i start up computer a sigal appears saying "no video input"


I'm assuming after a few minutes, it does get a signal from your computer and all works? It does take about 30s +/- 90s for a computer to generate an output video signal so if your monitor comes on first, before the computer can send a video signal, then you'll see that message. You should see the same message if you shut down your PC and leave the monitor on.

HCM Monitor has no display. When monitor started it becomes on but no display.All the function LED Becomes on.


Try disconnecting the monitor from the video connection.
Disconnect the power source and allow to set for several minutes.
Plug in the power source only and see if you recv. a no signal message on screen.
If not, you most likely have a bad display board or back light problem.
If you do recv. the message, you have a problem with your video card.

Monitor screen begins as computer is booting up and then screen goes black. Message says there is no signal.


If the power light dims or changes color after the no signal message comes up, that means the monitor went to sleep.
While the monitor is plugged in and on and the computer is also on, Try unplugging the VGA cable from the monitor. wait 30 seconds and then plug it back in o see if the power button light comes back to normal color and the screen flashes on.
If not, then the monitor is not getting a signal from the computer.
If using a desktop computer,Try a different cord or try the monitor on another computer.
If using a laptop, you need to activate the laptop to use an external monitor. That can be done through the display settings, OR, most laptops have a shortcut key feature which usually involves pushing the Fn key and one of the F keys at the same time. The F key may say CRT/lcd or have a picture of a monitor and a screen.
If the power light does light back up and still no picture, There may be an internal issue on the monitor

How to remove "no composite inpute signal"


If you have the same problem with both monitors, it sounds like a display card setting or problem.
The chances of you having the same problem with different units is 1- 50.
Try the monitors on a different PC and get back to me.

Syncmaster 203B LCD not working with Vista 64


I would first recommend reseting the bios, if the monitor still is black then it may be a problem with the graphics card

When I boot my PC up I get a blank screen and a message saying no signal then the screen goes into standby mode


OK, it's gonna be one of these 3 things :

1. The cable linking your CPU to your monitor might not be properly plugged or has been damaged. You should hence ensure that the connection between the two devices has been properly done and that the cable’s state is fine. 

2. You might be facing a problem with your monitor if the CPU makes a single beep error sound when you switch on the system. You can check whether the problem comes from your monitor by testing it on another CPU. If you still have “No Signal” error displayed including the error beep, I would strongly suggest you to try to get your monitor fixed by a competent technician or to get a new monitor. 

3. If you receive several error beeps when starting the computer, this might be linked to a graphic card dysfunction. You can refer to the motherboard notice or check that the connection has been properly set

Turn on the monitor the screen says "out of range" in a small window and turns off


Lower down resoluction and color quality to minimum on your pc, using 'display properties' in Windows. Connect the monitor back to pc with minimal settings. If it works is done.
If it still does not work there is a major problem with the monitor. In this case It should be opened and tested inside following schematics. In this case you may need to take the monitor to a service in your area.
