You'll need to check the cable connections and the computer that it is attached to. The monitor may be going into standby mode because the computer went into Suspended/Hibernate mode. Try restarting the computer. If you're unable to do this, try a hard power off and then try to turn it back on.

Hi there. My monitor has been working fine up to yesterday. I have all connections plugged in and i turn on the monitor and then the ACER sign comes up and then it says No Signal. and then the blue light...


Your monitor is fine, the problem lies with your computer. Your monitor is not receiving the POST signal from your computer. I suggest you remove your computers graphics card and plug your monitor cable into onboard graphics, then power up and see if the monitor gets a signal. If it does then it means that your graphics card has stopped working. If you still don't get signal then I suggest you take your PC to your local computer shop and get a qualified technition to have a look at it just in case the motherboard is damaged. You can also try out your monitor on another system just to be sure.

I just got a used syncmaster 203b monitor. I hooked it up and all I get is a black screen. I downloaded Driver whiz and hooked it up again. Still a black screen. Still get a black screen the blue light is...


Make sure that your computer unit is working. Sometimes we suspect that it is a monitor problem but usually, it is a frozen CPU set.

When you turn on the monitor, it should light the blue led and after a while, when it does not receive signal from the CPU, it will turn orange. If that is the case, the monitor is functioning well.

So what could be the problem?

Make sure that you hooked the monitor to the right VGA port. If you have an internal VGA port (built in with the motherboard) and you also have an external Video Card, you should hook it to the external VGA port and not the internal one since it is overridden by default.

Do you hear the "short beep" sound when you boot your PC? That signals a good video system. If you don't hear that beep sound (provided your PC's speakers are okay), you should open your CPU case and try to remove your memory modules (RAM). Clean the pins with an eraser and put it on.

Now, your computer should work fine and so with your monitor.

Blank Screen


Common problem in monitors are bad caps in the power supply, that is the first place to check, look for bad caps with bulging top/bottom, see example of failed VIEWSONIC monitors due to bad caps here (worst case will be bad lamps): http://s807.photobucket.com/home/budm/allalbums
Post back what you see so we can help you further.

Not able to turn it on. for no apparent reason the screen was black after setting overnight. The pilot light was on. tapped the space bar a couple of times thinking the computer would wake up and desk top...


I have the same monitor & just had same problem. Did you find a solution to your problem? This is the second time my monitor has done this. The first time I had problem i unplugged it and disconnected it from pc. Plugged it into power source and blue pilot light came on then went off. I did see the LG logo on screen before it shut down. After several times doing this and pressing the power switch repeatedly it seemed to reset and recognized it was not receiving a signal and indicated this. I then reconnected monitor to pc and all appeared to work fine for several days. Now I again have same problem after sitting over night.

Just turn the monitor off and on,,it should cure the problem,,also,,,tap the space bar on your laptop,,,,also,,you may want to change your settings on your laptop to prevent it going into sleep mode, or standby state,,which is what is causing this problem with your monitor.

no signal indicates a couple things... i suspect your computer isn't even booting up. reboot the computer while tapping the F8 key.... you should see writing on the screen... boot to safe mode. after it sucessfully boots up... reboot again... should be fine.

I hooked up my new acer p191w to my dell laptop 1525.HELP!


Not sure what the problem is, but I would suggest pressing the Fn+F5? There is a function key that toggles from dual screen, just the laptop screen or just the monitor. Hope that helps..
