Cannot see Screen contents

When I turn the monitor one I can see the screen contents for about 1 second before it goes black. If I turn the monitor off and back on, I can again see the contents for about one second.

    I have the same problem with a Westinghouse LCM 20v5 flat panel LCD monitor. Initially after hibernation, the screen would show for 1-second, then go black. I kept the screen on during hibernation and that worked for a few days, now I cannot get the monitor to recover, even after re-boot.

    Same problem with the L2046NV. Stays bright for a second and then goes dark.

    if you keep pressing the power button on and off eventually it stays on until it is turned off or hibernates again

I fixed it! It's the power supply board.

The Westinghouse LCM 22w2 has bad capacitors on the yellow power supply board. This is a common problem plaguing motherboards and LCD flatpanels that use capacitors from Taiwan. If you know how to solder, or know somebody that can, it's actually a pretty easy fix. Take out the yellow circuit board on the inside, write down the specifications for each of the capacitors (the cylindrical things) go to the electronics supply store and get the replacement capacitors. You can go over the voltage specification (not under), but keep the capacitance value matching. Replace one at a time. Go to www.badcaps.net for advice, tutorials and training on doing this. *You really should replace all the capacitors*, but the very large one next to the power plug I did leave on the board because I couldn't find a match. To my delight, it was working as new!

I saved a ton of money fixing this, it's definitely worth learning how to solder to do this.

Why does screen go black after a few seconds


Hope this helps.... Your monitor has an inverter issue. You know it's an inverter problem when:
1. Your monitor starts normally and displays the startup/desktop screen for a while.
2. Then it suddenly goes off, leaving a blank (black) screen or a very dim display.

To fix this black screen problem, change the inverter board (based on your monitor brand).

Black screen


• 1) TAKE OUT YOUR LAPTOP BATTERY
• 2) REMOVE YOUR AC ADAPTOR CORD, that's the wall power, remove it.
• 3) NOW HOLD DOWN THE POWER BUTTON FOR 30 SECONDS.

That will drain any static electricity that has built up on your laptop system board and many times fixes the problem of a black screen. After the 30 seconds re-connect your laptop to the wall power and hit the power button normally and see if the laptop comes back up.

Replace your battery.
Restart!

Screen turns on 1 second then turns black


With a known working monitor try it on the computer. If the monitor stays on then you know the original monitor is bad. If the monitor goes off after 1 second again, then you know that the video card is bad.

Used as second monitor suddenly stared to go dark


If the screen is lighting up for a fraction of a second when you turn on & then goes dark, this indicates a fault either with the backlights on the screen or the inverter part of the monitor. You can check the backlights if you have access to a backlight tester, you need to remove the rear cover & connect the backlight cables into the tester, if this checks ok then look for a problem on the inverter board, checking the capacitors for any signs of distress.

Monitor goes blank less than a second after turning on.


I start my computer and turn it on, and everything looks fine for about 1/4 of a second and then it goes black while leaving the power light green. I can only see the screen again after turning it off and on, but that's only for another 1/4 second. What's up?
I got my rosewill flatscreen as a hand me down from my father. I've had it for several years now. Was working fine until a month ago. When I turn the computer on the screen goes black after 1/4 of a saecond. I have to turn it off and on anywhere from 10 to 20 times before it stays on. I have checked all plugs to the computer and outlets. I have absolutely no idea whats causing this.

Black screen


How old is the computer? Make sure that the power light comes onto the monitor when you plug it in, should be orange and then turn green when video card syncs with it when PC is turned on. If you are getting black screen when PC is powered on:
1. Bad video card
2. Bad video cable
3. Bad monitor
1Solution: Try using a different monitor attached to this same PC and see if it works. If it does, then its the monitor, its cable, or its power supply. If it doesn't work, then its the video card or the video cable coming from monitor.
