    Lots of things can cause this. What OS are you using?



    When you start your computer (with the monitor turned on) is it on until it hits Windows?



    -If so, restart in Safe Mode and under Device Manager - uninstall all monitors, reboot in normal mode and Windows will reinstall what it needs. Remember to not set your resolution/refresh rates to high for the monitor you have.



    -If you have the type of video cable that can be flipped around (same connection type on both sides) - remove cable from PC/Monitor and flip and re-seat both ends.



    -Try a different power cord on the monitor (assuming you have the type that uses a standard cord).



    -If you are using any type of power strip - remove the strip from the equation and plug the power for the monitor directly in a wall outlet.

If you can try it on another unit , If it still does not work, Then the most likely culprit is a bad power supply. If you know any thing about soldering replace the capacitors they are probably bad but being that these things are being built so cheap.It could also have a bad inverter. not repairable by average dude.If you open it be careful and do not attempt unless you feel comfortable with a solder Iron.Hope this can help you Good Luck. www.IrionsTVshop.com board re builders.

    After reading the solutions put on others I regret to inform you they are a wast of time. I have been repairing for years and encountered this problem about 100 times it has always been the monitor. By your description. If you tried it on another monitor no go, What else would you expect. Two computors same results as I said, Its in the monitor. Not for a beginner. I wish I could give you a simple answer that would work for you.But EXPERIENCE tells me.Monitor

I have 2 of these monitors with the same problem. On power up the green led will light & remain on but the screen remains black. On one of the monitors the screen will light up for a few seconds then...


The inverter that turns on the back light may be bad - it's suppose to create the high voltage pulses to fire the CCFL back light lamps. Apparently the back light turns on after a few seconds however, it cannot stay on because the inverter might be bad. If you connect a known external CCFL lamp to the to the inverter output you can isolate the inverter.

The screen goes blank after 1 second display, flicks back again to the display for 1 second and back to blank, this goes on non stop. The little led next to the on/off button goes from green to yellow...


pandres, Your monitor will need troubleshooting to find out reason why the 2 "cold-cathode-fluorescent-lamps" fail to remain lighted. They provide "white light" so you can see what is on the lcd panel. Connect a "known good" monitor to your pc to prove monitor is bad. If pc is ok, then your monitor will need repair. This type problem not new and is very common for all brands of ccfl back-lit lcd monitors. Watch some video clips at YOUTUBE that show disassembly and repair of ccfl lcd monitors.

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.

Screen Goes Blank


Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.

Pavilion f1903 silver goes blank seconds after turning on.


The monitor you have has bad components on the circuit boards inside.
This is a classic problem with all LCD monitors.
I rebuild them on a daily basis so I recognize the symptoms.
I would suggest finding someone who can do component level repair on the circuit boards inside.
I also suggest not trying to repair yourself as there are many breakable components to them as well as components inside that do not like static electricity discharges.

NEC MultiSync lcd 2010 monitor blank screen


This is the common bad capacitor problem. The caps have died inside, and they can be replaced. If you have basic electronics skills, you can go in, order replacement caps, and unsolder and resolder. If you can't do it yourself, you can take it into a shop.

Here is a link to the Cap plague that explains what happens in detail. But I repair these all the time with that symptom.

DiamondPoint V71LCD Not displaying image


The LCD screen may be burned out. There's whats called an invertor board and there is an electronic ribbon strip on the LCD itself. If you look very carefully you can probably see a faint image on the screen. The LCD screen will need replacing. Before doing anything with this monitor, try it on another computer first and if you can try another monitor on your computer. Other than that, there really is nothing you can do but replace the monitor.
