UNSOLVED
Screen flashes white
I was on my laptop when I started playing a game and the screen starts flashing white. So I close the game, doesn't stop flashing. I log off my side and it doesn't stop flashing. I restart the computer and it doesn't stop flashing. I hook it up to an external monitor and that does not flash but the screen on the laptop still does. I run the LCD test with the Fn button first and I say no on the display it gives me code 2000-0334. I run it again and do not answer it gives me code 2000-0334. I shut it off and turn it on with the "D" held and it flashes colors but it still blinks white. All the tests on the dell website for diognostics I have run say there is nothing wrong. Please help me fix this.

Hi slombardo,
The 0334 error is a user reported error - see this link - http://dell.to/1IuETMX
What is the exact system model? What is the OS installed on the system? Were there any bluescreens / system crashes before the issue started? Did the system overheat at any point?
When you press the D + Power button, do you see the screen changing solid random colors at first, before it begins to flash white again? You say the display on the external monitor works fine. Please confirm this. If the display on the external monitor works fine and if you DO NOT see the screen changing solid colors on D+power button, then the LCD on the system is faulty.
Based on the description of the issue you have initially reported, I would suspect both the motherboard and LCD might have failed. However, if you are able to diagnose the exact problem by following the steps above, then you might be able to isolate the issue to either the motherboard or the LCD.
Keep us updated.
