If your laptop monitor is going out, replacing the LCD Inverter or the LCD screen is a bit tedious but possible. If you are not comfortable in doing either of these, I would suggest going to a local computer repair shop.

Samsung 226bw visible flickers just after it is turned on


You may have a faulty inverter or loose power inverter connection. OR
You may have a defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

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.

Screen Flickers


Hi I've recently fixed 2 laptops with a very similar error, neither of which were Hewlett Packard Compaq's. That aside its a fairly common error and that is a loose connection. Unless you've a lot of experience in dismantling and reassembling laptops, I strongly reccomend taking it to an experienced technician.

I hope this helps

"Flickering" screen


Connect an external monitor to the laptop and power it up, if you see a clear image on an external monitor, this means your video card is OK.

If you see a dim image or flicking image on the LCD screen it means you have a backlight problem.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Backlight is acting like a bad flour. tube .. everthing else OK


Normaly the backlights have a life of around 40k hours of working.
If your monitor is 3-4 years ,the backlight tube/s could be defective.Your description seems to indicate tube aging.

It's possible to replace the tube but needs a good amount of technical skill.
Do write if you need more help,Please indicate make exact model no etc.
