The screen flickers, have to reboot it

Sometimes in the middle of any process my screen just went crazy, the contents flickers - they scroll over and over the screen. The only way to solve it is to reboot it. A friend indicated that the resolution might be the issue. However, after I reduced the resolution it still happens, just less frequently.

Start by checking Dell's support site for updated video drivers, then uninstall the drivers for the screen from the device manager, then reboot. It will find and reinstall them. If this doesn't cure it, then this is going to be a hardware issue. Start by checking the screen connections, they sometimes work loose. If the connections are good and the problem persists, it's going to be the inverter or screen, and unfortunately, replacement is your only option.

What could cause my VIDEO CARD to fail?


This could be a simple failure of your video card. However, I had this happen and found out it was a heat sink that had come loose from my motherboard. (Heat sinks are the aluminum blocks, with fins, on top of CPUs on your motherboard, or on advanced graphic cards.)

1. Power up the phone (of course)
2. Once the main screen has appeared press the "cube" button.
3. Select the blue and silver cog icon (Settings) at bottom right of screen
4. Select the General Settings Icon, third option down (displayed as a puzzle and cog icon)
5. Scroll down to the last but one option. (Samsung TouchWiz UI is the final option).
6. Three Arabic options are displayed. Select the middle option (English).
7. Select the Arabic option at the bottom left of screen (if the following message doesn't appear then I got it mixed up and it should have been the right).
8. You should get an English message asking if you are sure you want to change the setting.
9. Phone reboots and bingo it should be English.

My NC-10 screen just went crazy. I can tap on the


You may have a defective CCFL backlight, it may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickers 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 replace the CCFL lamp.
To determine if the video card or the LCD is faulty, 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. It could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out, this is the most likely case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.
