Try setting your graphics card output to something simpler like a basic 640x480 resolution 64k colours and see if it still does it... it maybe that you have the resolution/colour depth to high for the monitor to properly handle

if it is stable at the lower setting slowly increase untill you reach a point that you and your monitor are both happy

New monitor purchased with a package with compaq desk top, but trying to use with a Acer desk top, screen comes on , but then goes completely dark after about two seconds. If switched off then on, again...


Could be a faulty monitor, or could be missing the driver information for the monitor. Usually when you first connect it will use a generic driver to start but then should automatically download and install the correct driver information for the monitor. Could also just be a faulty cable, power or VGA, HDMI, which ever you are using. Try using different cables first, then you can google search for the correct driver and manually install it.

The panel initially displays and then goes blank


johnerm, Good going John! At least YOU tried doing a swapout to another KNOWN GOOD pc to prove out that the E153FP is indeed the culprit!!! Now for the hard part. Do you have a bright flashlight? Reconnect E153FP to pc with WIN-desktop as the displayed image. then and only then turn on E153FP and note the time it takes to GO TO BLACK SCREEN. Is it 1, 2, --5,---20 seconds???? Now point at different angels about 1 inch from screen a bright flashlight to an area that "should" have a desktop "icon" showing. LOOK very closely!! If you SEE a very faint image of the desktop the units "switch-mode-power-supply" is in PARTIAL SHUTDOWN mode. (still has +5v or +3.3v to supply vga/lcd interface board) If you SEE NOTHING, then SMPS is in FULL SHUTDOWN mode. Get back to me, 12fixlouie with your SMPS flashlight evaluation and pay a visit to YOUTUBE fyi search and view video clips of "LCD monitor disassembly" and "LCD monitor repair" to see if DIY interests you! Also try www.ccl-la.com/badcaps.htm run by another tech on fixya nickname "buddymc" fyi. If this was of some help, rate this response on fixya. 12fixlouie aka louie12fix or lmistyrel @ aim.com

Lg w1934-bn blank screen after start up, power light on . same problem occurs on different computers used.


Reason 1: Wetness The number one reason why computer monitors go blank is - wetness. Believe it or not, when your computer monitor is exposed to humid air, sometimes water can condense and accumulate in the monitor. This causes the monitor to malfunction and go blank. I've had this happen to my desktop PC at least three times before. What you need to do is to leave the monitor alone for some time and allow the water to evaporate. That usually solves the problem.

Reason 2: Faulty Graphics Card The next reason why your computer monitor goes black is due to a faulty graphics card. The best way to detect this kind of problem is to connect up a new monitor to your PC, then check if you have a blank screen. If you continue to have a blank screen, then it's likely your video card is faulty.

Reason 3: Faulty RAM This one is less obvious and less common, but it can happen. You might sometimes get bad RAM modules which prevent your PC from booting up even to the basic BIOS startup screen. To detect this kind of problem is more troublesome, you might need to remove those RAM modules and insert them into another computer.

Reason 4: Loose Connections Another reason why your monitor goes blank is due to loose connections. The connection from the monitor to the mains is usually a culprit, as is the connection between the monitor and the video card. Check those connections before you declare your computer monitor as faulty.

Reason 5: A Short Circuit In The Motherboard And the final reason why your computer monitor goes blank? It's possibly because of a short circuit in the motherboard. This is the most undesirable outcome of course, as you might have to replace your entire motherboard. However, it's possible that this can happen - so keep your fingers crossed and hope it doesn't happen to you.
i think this will help.
please rate my solution.
have a nice day.

BeNQ FP71E Monitor won't display desktop


The problem seems to be with the monitor.When there is no Display,if you power-off and on again do you get a Benq Startup screen?If not the problem should be dry solder on the Invertor board.Try tapping screen lightly,if it comes on the problem is dry solder on Invertor board.
