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.

It is probably a GPU overheat issue where the BGA chip has desoldered itself.
Reballing the GPU should fix it.

Dell Inspirion Laptop Screen Randomly Flickers, Then Blacks Out


not to get to concerned just yet, a few tips, when you press on the top of the laptop case by the screen area in the back of the laptop do you notice the screen flickering off? and when you let go dose it come back on? if so this can be a faulty wire or bad inverter, they are actually both very simple to fix and relatively cheap fixes.

Dell LCD monitor has flashing lines, color distortion; random


I'm not an expert but I will give you a couple suggestion, who knows might help might not. It's worth shot.
First open your internet explorer, when webpage comes up, go to the top of you screen and click Tools, Internet Options, Advanced, scrool down under the list marked Browsing, put a check in the box next to "Use smooth scrolling." And try it again.
The next thing is try you other cord, it could be your video card.
If it works good on the other computer, chances are, The comupter is the problem.
If the computer has Windows XP on it you could try a restore point.
Go to Start button, Click All Programs, Accessories, System Tools, System Restore, Click on one of the Dates that would be, before you remember having the problem, click next, let the computer reboot. And, see what happens then.
Hope that helps some...

Screen flickers for about 20-30 seconds sporadically


Try looking at the LCD screen at a sharp angle to see if ghost-like video can be seen during the 'off' time of the flicker.  If video is still present even though not that visible, then either the backlight or its power supply are failing. The color problem could also be caused by a backlight lamp that is not ionizing completely.

Screen seems to dim and there is flickering while watching


This is both a common and fairly easy repair in this unit. Remove the back, but not all of the back needs to be removed to access the power supply area and locate the power supply board. You might find that all three E919,E920,E921 of the 35v/680uf caps in the upper left of the PS board are bowed and/or vented. Replace all three of them even if they test good...
Next, esr the remaining caps. Last one we did here in the shop there were 16 total that we replaced, many were orange in color but I don't have any notes on their value. The orange color of the cap is a lesser temp range we used 105 degree or better as replacements. Some we used a higher rated cap (higher voltage) same uf rating. Gave it a greater reliability.
Good Luck!
