Capacitor is going bad in powersupply.Leaky!

  • Anonymous Sep 11, 2007

    Caps are usually round with 2-3 legs and they usaually say something like a number and then uf,pf,mf, and then some type of voltage like 16v,50,100,250v etc. So if you are not familiar with this then it will be hard if not impossible to help you fix. You will also have to solder the bad cap out and put in good one. If you can not do this then you may need to take to technician.

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.

Thumbs up
Thanks

Dim monitar with flickering screen

Hello,

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: www.ccl-la.com/badcaps.htm 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.

Buddy

System problem

Try another monitor.  If that doesn't work reinstall your video drivers with control panel system device manager.

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

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.

LCD goes dim within 1-2 minutes

You could have a bad "inverter" or flourescent backlight tube, or a problem in your power supply.The only way to isolate the problem is to check each component in sequence.If your hard disk and DVD / CD drive are still working when your screen goes dark, then I'd say it's the "inverter". You'll have to take it to a repair shop.

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.
