Sounds like a loose connection somewhere. find a local computer repair shop. Often those guys can diagnose a common problem just by glancing at the symptoms. GeekSquad is great but costs lots.

I am sure that the issue is related to the cable that connects to the LCD Display or the LCD Backlight.
There should be some connection shortage because of which the LCD flickers few times as stated by dan231.
I Recommend you to get the Notebook examined as soon as possible before something really goes wrong...

SOURCE: i have a fujitsu lifebook N6460 the screen flickers and goes out

Sounds like you back light or LCD inverter is going out, If you don't hear a whine then it is just the LCD screen, if you hear that whine then it is the inverter. An inverter will run 40-60 dolloars as opposed to and LCD screen which usually start around 100 and go up...

Hope this helps, if so please rate my solution accordingly.

Since it seems as though you dont move it very much you might be able to hook an external monitor up to it and using the Fn+F5 button swap it to use the external monitor untill you can get it repaired.

SOURCE: bottom half of screen sometimes black or bad video

Probably you have to change your resolution settings and what type of operating system are you using?? or you have to get your computer checked out by a professional to be safe.

SOURCE: Screen Flicker and goes black

Hello,

I had this issue with my r700 last week. It can be resolved without any hardware changes/fixes (if you have the same issue which it does sound like).

Samsung are aware of this issue and have released a firmware upgrade for the system BIOS in order to implement a resolution to this monitor flicker problem.

Resources
Visit the following webpage -
http://www.samsung.com/uk/support/download/supportDown.do?group=&type=notebookcomputers&subtype=rseries&model_nm=NP-R700&disp_nm=NP-R700&language=&cate_type=all&dType=D&mType=FM&vType=&prd_ia_cd=05010400&model_cd=&menu=download

Instructions
1.download the file listed
2.double click on the file once downloaded to install the update

Additional
Something you and other r700 users may find useful is that the r700 is known as the np-r700 on the Samsung website-there are lots of useful downloads and guides available there.

Hi, i noticed that when I unplugged my HP the screen stopped flickering. I then re-plugged in the power, when to the Nvidia control settings, to PowerMizer, and changed 'ac outlet' to Maximum Power Saving.

Not the world's greatest solution, but hey, working laptop now.

Cheers,
Andy.

You need to replace the screen. Look for a replacement on ebay.

It could be 1 of 2 things, either your monitor is going out on you, or your graphics adapter is going bad. Depending on how long ago you purchased it, and from whom, I would contact Dell service to find out if they can return it, or give you any suggestion.

When it flickers, can you still see the text when the screen goes dark?
May have to use a bright flashlight set right on the display to see
the text on the screen beside where the light sits.
That will tell you if it's the backlight.

You can also look at a grazing angle into one of the edges to see if the
backlight is flickering when the display does.
When it's cold, does it start with a slight pinkish color? That can be
a sign of backlight going bad.
Anything interesting happen when you flex the cable by moving the screen?

I'm not saying it's impossible, but I've never seen software cause
consistent screen flicker. And if the vga port doesn't flicker, sw is
even less likely the problem.

If you bet the odds, you'd bet on a bad display cable.
Won't hurt to try replugging it.

If that doesn't help, then your monitor may be dying....

Sounds like a loose connection at the inverter board. Laptops use an inverter to step up voltage to drive fluorescent tube(s). The problem could be at the inverter or at the tubes.

MD96015 Monitor problem


Sounds like you may have a bad LCD backlight or inverter. When the screen is dark, take it into a dark area and see if you can see the screen dimly showing. Or, shine a flash light on the screen and see if you can make out anything showing up.
Try this and let me know what you find.
