    Are you sure you plugged it into the right video socket on the back of the computer? There might be more than one.

Make sure the cable is plugged into the video in. Shut down the computer and unplug it. Unplug you monitor again and also check conections by removing the cable make sure no pins are bent on the monitor or the conection to the computer. Plug all back in. Turn the monitor on first and then the computer. I hope this helps. If not let me know I will need so more info. Good Luck.

Monitor says "No Signal" when trying to wake it up


I had that problem awhile ago, but the issue was a loose connection.

If you test your PC with another good working monitor/cable and still receive a no signal message, then the problem is with your PC.
The solution could be as simple as dust inside the unit interfering with the signal, and needs to be blown out, or try removing the power cord and hold-in the 'on button' for about 30 seconds to a minute; then reconnect the power cord and turn it back on.

Other solutions: open up your PC and take out and put back in the video card; remove the ram memory strips, rub the end gold colored strips on a clean cloth and put them back; or maybe you have a bad video card.

Why is my monitor shuts down after just using it a few minutes?


This could be signal cross-talk from touching wires. Separate the wires in back.

My Acer S200hl monitor suddenly has horizontal white lines on the screen. It gradually fades from very severe lines on the right side to virtually unnoticalbe lines on the left. Any ideas?


It's dying. Pretty much simply that, something electrical or electronic (connections from panel to panel edge connectors, connection to circuit board, or internal to a panel matrix chip). Very likely unserviceable, if under warranty, take it back for service. Only other thing, check connector under back of monitor (if it has a connector at both ends). It's an Acer monitor, they aren't terribly durable, so if it's more than 2 or 3 years old, it's probably on it's way to deadville.

I cannot get my Dell E173FP out of Powersave. I switch on the computer, but nothing appears on the monitor screen. I press the menu select on the front of the monitor and it says "In Power Save mode,...


Hi Ron,

It sounds like the monitor is not receiving a signal, or that the signal is one that it can't display (wrong screen resolution etc).

Can you make sure the monitor cable is securely plugged in at the monitor and the PC?

Do you have another PC you can try with that monitor?

Do you have an spare monitor cable you can try?

Is this the only monitor connected to your PC or are you using is as a second monitor?

I'm happy to try and help you solve this.

Kind regards,

Chris

Samsung Monitor 192N light turns green when powered on then goes out after few seconds


this usually means the monitor is not getting a signal
  • i would check the hdmi/dvi/vga cable connections dirk_s.jpg
    both on the back of the pc and on the back of the monitor.

  • if the connections are tight, and plugged in well, maybe try and connect it to a second computer or laptop.
    • If it works the problem probably lies with your gfx card in your computer (verify this by trying another monitor on it)
  • If it doesn't work on those i would try and replace the aforementioned cable (usually pretty cheap)
  • if the problem still persists the monitor would probably need to be replaced as its defective.

Error message on Syncmaster- check signal cable


sounds like it might be a graphics card. if u have an old graphics or vidio card, open the case and remove your card then install the old one. if it works now youll know your card is bad. If u have an old video card and an open pci slot install it and move the monitor cable to the old video card plugin. if it works now same thing your graphics card is bad. to know which card to remove just remember which one the monitor is plugged into.

No signal on monitor


You probably have 2 monitor connections. you have a standard one, and one that is through a graphics card at the bottom of your tower. Check for that second connection and switch the plug.. that should solve it.

Monitor has no picture


Yes! :)

Your monitor is not the problem. Check all the connections from the back of the monitor, to the computer.

"No Signal Analog" means your monitor is working perfectly, however is not receiving signal from the computer.

Didnt find any loose cables?
Try unplugging everything. Leave it unplugged for at least 5 minutes. You need to give the system time to drain all the excess power.

Again your monitor is fine, blue light > No signal > orange light is totally normal for your montior.
