My monitor will dim itself and I have to reset it so I can view the screen. some days, like today it will go dim every 15-20 minutes even when I am typing.

This sounds to me to be a problem with the CFL tubes, soon they will stop working altogether and your diplay will be very dim, or may not come up at all. In which case if under warranty return it, if not you may need to replace the CFL tubes.

Asus Monitor boes blank and comes back after power recycle

1. You can see images on the screen for a few minutes. That means there is nothing wrong with your computer.

2. When your screen goes blank, if you disconnect and then reconnect the monitor, it shows fine again for a few minutes before going blank (or dim) again. That means the problem is not with you video card.

3. It always shows the image after reconnection for exactly a few minutes before going blank again. yes? this means that there is nothing wrong with your cable.

Conclusion: Sorry, but you do not have many options. I bleieve that the problem is with your monitor that's going bad. Its far cheaper to get it replaced than to repair it.

Dim monitar with flickering screen


The problem can be caused by 1 of 2 things either your power supply is going out or the backlight bulbs are going out. The most likely cause is the power supply. If you are willing to do a little soldering you should be able to do the repair. If you go to our web site at: We have a section on monitor repair. Look under the Samsung 930B it is the same as your monitor.
If you don't want to do it yourself we do offer a repair service, email me if you are in need of that.

I hope this helps.

Dim monitor

5 years old, lamps are good for about 50 000 to 60 000 hours of life you would have to do the math based on average number of hours per week/month and see where your are, several things to check initially are inside look for blown capacitors, you can find images all over the net Google "blown capacitor image" and you will see what to look for.
Next could be inverter failure as they get old and work pretty hard. Last the ccfl lamps may be dieing of old age like the florescent lamps in buildings, they get burnt at each of the ends and have a hard time lighting up.
let me know what you find.

Sumsung 930b goes dim,and flickers after about 3 min.

This sounds like the inverter has gone bad. If the bulb were bad only, you would see a faint image on the screen with a flashlight.

The problem is on this monitor, it will probably cost about $100 or so to take it to a shop to get it fixed, and that is nearing the cost of a new monitor.

If you are a little bit handy, and can disassemble the monitor, you can replace the inverter. The hardest thing about this, is getting the monitor faceplate open. Just use something firm and softer, such as a nylon spudger (this is something you can find online) or you can carefully use a thin scredriver. You just have to be careful, those cases are really tight.

Here is a good guide for general ideas on how it is done.

Monitor Randomly Turns Black

I have exactly the same problem with my Benq FP71E+ ..

What i found is a temp fix is this :

When monitor dims and goes black i turn it off , hit the bottom left side (near the BENQ logo) turn it on again and it works ..

This works every time for me . But after a while it switches off again , could be 5 minutes could be 5 hours . Its random

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.

Monitor has shadows from left to right

Try changing the cable that connects the monitor to the computer, that might improve things slightly, but because you said that it works for the first 15 minutes I'm skeptical that the cable has anything to do with it.

The monitor is near the end of it's life. There's not much that can be done.

Monitor problem: screen goes black, then comes in scrambled

It sounds like this one needs component-level troubleshooting, probably in the power supply section. One or more backlights may be going out, too.
