Re: Monitor Problem:

You may be encountering a hardware fault that numerous people appear to be having (myself included).

Get a bright torch and point it at the screen once it's 'gone blank'. Look for any text / images that you'd expect to be displayed.

You will normally see a faint display which shows that the problem is just with the backlights. Unfortunately the inverters for these are built into the power supply (Delta Electronics, model no. ADP-40AF) so you will more than likely need to replace this. It's probably easier, simpler and cheaper to buy a replacement (non-Acer) monitor!

SOURCE: Blank ACer X221W Monitor

Hi this is the way how to examine what's wrong with your LCD monitors. Power on both CPU and monitor. After it went dim and blank, you have to check if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. Like me, I can see window image using flashlight and check lamps inside. Some of them were broken and it is easily replaced. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so.

SOURCE: W1907 Monitor Goes Blank

I had the same problem. Screen would often go blank when entering or exiting a program, usually a game. Happened in both DVI and VGA modes. Pressing MENU then SELECT would sometimes be enough to bring it back (monitor would switch to inactive input, then back, the video would reappear but often re-disappear in one second). The blank screen was actually an extremely dim image. Plugging cable into known good monitor showed video signal was fine. New drivers downloaded, no help. Powering monitor off and back on would often be required.

The solution: I returned the monitor to the store and exchanged it for a new W1907. It works!

SOURCE: monitor goes black after a few seconds

1) It could be your power supply is going bad or not strong enough to keep the monitor on.
2) It could be a memory issue. Video is one of the signs that your ram is bad.
3) It could be a loose connection or the monitor itself.
I would suggest first unplugging all the connections to the monitor and pc then plug in again and restart. If it still turns off try a monitor that you know works. If you still have the problem try changing your memory sticks. It's unusual that it would be a video card/ on board video because it usually either works or it doesn't.

SOURCE: I have a Dell monitor model #1901FP when my

The solution I am about to describe refers to a backlight problem, which is most common in Dell 15,17 & 19" monitors. The symptoms are as you describe:

  • You power on the monitor, the green on/off switch illuminates and the display works for approx 1-2 seconds and then goes blank.
  • The green on/off switch stays illuminated but the screen remains blank
  • If you shine a torch into the LCD matrix you can see the display being rendered faintly
  • Switching the monitor off and then on again illuminates the display again for 1-2 seconds before going blank again
This is a backlight fault and is most likely to be caused by the failure of two of the four driver transistors used to light the lighting tubes in the LCD Matrix. This fault is easy to repair if you (or a friend) have a soldering iron and a voltmeter.

Inside the monitor there is an inverter board that acts as a power supply for the monitor and the logic necessary to control the backlights (illumination and brightness control). There are four lighting tubes, which are controlled by two lighting circuits (two lighting tubes per circuit). At the heart of the inverter board is a chip that monitors feedback from the two lighting circuits and closes the back-light circuit down if either of the lighting circuits fail, thus any component failure will exhibit the same symptoms.

The transistors which fail most often cost pence to replace (types C5706 or C5707). However, their failure in unlikely to be the cause of the problem. My first crack at fixing this fault, by replacing the transistors, resulted in them failing again within 24/48Hrs. The cause of the problem will be dry solder joints or loose connections on the high-voltage side of the circuit, usually on the backlight transformer in the effected circuit. If you re solder each of the connectors on the transformer you will save the transistors from blowing again - the transformer generates 1,400Volts for the lighting tubes and at this voltage, arcing across the a dry solder joint, will quickly destroy the transistors again.

No soldering iron? - A complete inverter board replacement is also reasonably cheap and easy repair. These are widely available.

Sorry of this is more detail than you expected but it may help others reading this article.

We are using the same monitor type.. humm it's good that i already had experience with it. No drivers needed to install this monitor, check the connection to the PC and to the monitor, make sure they are inserted properly. Sometimes when you put on the PC first and then power on the Monitor causes this problem. The best recommend resolution is 1440X990, good luck..

Check your connections to the PC. Make sure that they are nice and secure. If there is a resolution problem setting it should display the boot process and then go blank after starting the operating system.

Possible that the HV inverter or the CFL tubes are going bad / defective. I suggest to bring the unit to an authorized Acer service center for proper check-up / test & fix the problem. regards
