Question about NEC Mitsubishi Diamond Pro 730 (White) 17" CRT Monitor

Monitor turning itself off

Hi, I'm not sure what is wrong with my monitor. When hooked up to my own PC it works fine (hence me being able to type this message out) but when its hooked up to my parents PC (an Evesham) there are problems. Today it started doing a thing where it will boot up as normal, the PC starts and the monitor automatically turns on from standby. It starts to loads up Windows, but just as it gets past the initial loading screen, the monitor shuts itself down again. If I turn it off and on, it just keeps shutting itself off. There is no problem when it's hooked up to a different PC, just the Evesham. Any ideas? Julie

May be a problem with the desktop picture. I had one of a light at the end of a tunnel. I changed the picture to a blue sky. My problem was 17 inch lcd would shut off about 5 times. I would keep turing it back on and off then it would start working.

You may have to go to safe mode to do this, if the the monitor is turning off to fast. Most have to hit the F8 key will the system is booting. That way everything will be set to default and you will be able to maneuver around and make the change.

But before doing that, Check the refresh rate that your parents Video is set to" Example: Your pc may be able to support 85khz refresh, but your parents may only be able to use 72khz max. This is located in SETTINGS>ADVANCED>MONITOR>REFRESH Select from dropdown box a lower rate. Though be leery of 60khz refresh rate(if you're in US) which may flicker under flourescent lighting. Maybe low as 50khz for Europe for flicker.

It sounds like the problem is with the computer's video adapter settings. It is very likely that the monitor cannot handle the settings. If you boot into safe mode, can you see everything? If so, then the normal mode settings are too high. Safe mode defaults to the lowest possible settings (thats why everything will look really big) Try turning down the resolution (Right click on the desktop, select properties, go to settings tab) to the lowest possible setting, and then slowly try turn them back up again until you can find the maximum setting the monitor can handle.

SOURCE: Monitor picture fades out.

I thought my problem was originally monitor related. However since I posted, the picture disappeared altogether, and my PC wouldn't even start to bootup. Fearing my mobo may have died I removed the hardware components, cleaned then re-assembled them. After all that, it turned out that my graphics card has a tendency to become slightly unseated. Once I was aware of this problem booting up resumed normally. It seems that the problem of the fading monitor picture seems to still occur, but soon after I use the machine after 'hibernation' state, and even then it doesn't always occur if I do use hibernation. I haven't used hibernation for a little while and so far the problem has not returned

SOURCE: Multisync LCD 1700V turns on then screen goes blank and shuts off

Does the power light stay on? If so, you have an inverter problem. If the power light goes off, you have a power supply problem.

I would like to remove the OSD warning pop out "Attention" from my monitor. What I need to do to achieve this?


If you are getting a message that says something like "Check cables" " no signal detected" or something like that, it is likely that your monitor is operating correctly. I would suggest checking your cables, make sure that the computer is turned on, and if that doesn't help, check if your monitor has VGA, DVI, or HDMI inputs. I am thinking that your monitor may be trying to display from the wrong source. This is what a VGA (analog) cable looks like. VGA cables are typically blue.

Another common connection that is used is a digital HDMI (left) or DVI (right) connection. DVI cables often have white end connectors. How your PC connects to your monitor will determine the source mode you want to use on your monitor. (Obviously this is the cable view but the connection on the monitor itself will look similar.)

If none of these tips helps, I would suggest hooking the same monitor up to a different PC or laptop, and trying once again to get a the display working. Again, make sure that the connection matches the source setting on your monitor. If it works on another PC, then your computer may have a video problem.
Otherwise, if it still does not work your monitor have a problem displaying via that connection. If possible I would suggest switching to a different type of cable and re-try the above steps.

When I first turn on the monitor I get a picture for about 1 second then it goes black. If I turn the monitor off then right back on I get the same 1 second pic then black. A different monitor works fine...


Make sure you are on the correct video setting on the monitor using the menu button.
If you are hooked up to dvi you need to make sure the monitor is on the dvi component. VGA same thing.


Hope this helps

I have a new Acer desktop model Aspire X1301 and it seems to work fine except for a complete lack of sound. I have the audio wire hooked up to the rear of the tower - there are several ports to choose from...


First thing I would make sure it is plugged into the correct port. Make sure it's the one with the headphone Icon...They are usually green, but i've seen some pink ones. Physically get behind it and look. Then I would make sure the 3.5 audio plug is plugged into the monitor. I looked it up and there are 2 speakers in the monitor. Then when the PC is turned on and you are playing music, check the settings on the monitor itself...the little silver buttons in front...make sure the volume is turned up. Also, check the volume on the PC itself down by the clock. There will be a little speaker icon..make sure that it's not muted or something. Hopefully this helps ya, if not post back and we'll troubleshoot some more.

Monitor turns off by itself during normal usage.


There are a few things you can try in order to narrow the the cause. First there's the easy outside-the-PC stuff such as:

- hook up a different power cable
- hook up a different video (VGA/DVI) cable
- You can always try switching to the other type of cable (try VGA if you're on DVI and vice-versa) to see if that makes a difference, assuming your monitor as both connectors.
- try connecting same monitor (and power/video cable) to a different PC for a day and see if it turns off there as well.
- For that matter connecting a "known good" monitor to your PC to see if that monitor also acts that way on your PC.

On the software side you can disable the power management features related to the display to see if that makes any difference.

If you were to connect this to a different PC with a different VGA/DVI cable and power cable and it still did it that I would say it's probably the monitor itself (unless the PCs were identical or something and under control of the same domain policies or some craziness like that).

At some point you probably want to call the manufacturer and see if an RMA is an option. I would recommend trying some things before that though. I hope this helped!

Monitor fine with 1 PC, no RGB input after windows load on other?


Lower the resolution on the computer to 800 x 600 and then hook up that monitor see if it at least accepts that and doesn't go black. You may have to go into safe mode to do it plus then go back into regular mode.

Dell display is dark


Leave the monitor hooked up to the computer with you booted up into windows.Go into the menu on the monitor itself. There should be a button on the monitor itself that will allow you to go into its own menu. From there try to find the brightness and contrast controls and turn them up. If after you turn them up the display stays dark then your monitor is bad and it will need to be replaced.

Black screen!


lets check a couple of things. I'm sure you know that a laptop can be hooked up to a external monitor or projector, There is a button usually F5 Or close to it that will turn your monitor off and send it to the external one. In some models of toshiba this will stay in effect even when you turn it off. You can toggle this setting by holding the FN key down and pressing the appropriate "f" key. try this first before you chuck it. There also may be a problem in the bios. Let me know how it turns out. Take care..Be mucho blessed... Mark

they normally turn off like this when they aren't receiving a video signal from the pc (same as when you turn off the pc). make sure that it is connected properly, and that the video output is activated. try disconnecting from the other monitor while its on and connect the problem monitor...if it still isn't working then there may be a problem with the cable or the monitor itself. Try another VGA or DVI cable. Hope this helps
