LCD's are made up of lines that project an image on the screen. These lines constantly move, sometimes up and down, and sometimes side to side...this causes a flicker often seen on older LCD monitor's.

How do you fix your HP laptop monitor that flickers?
AnswerI dropped my HP laptop and broke the factory screen. I plugged the computer in to an external monitor and it checked good functionally. I ordered and replaced the LCD screen only to be annoyed by an intermittent flicker of the new screen. It took a while to figure it out but I solved the problem. I have the HP G71-340US Notebook (17" screen). Once dissassembled the screen has a rail assembly on both the right and left side that it mounts to. There are 4 screw holes on each rail but the computer only comes with 2 screws on each rail mounting to the screen. My mistake was that I installed the top 2 screws in the top holes and the bottom 2 screws in the holes DIRECTLY ABOVE the bottom holes. There is a wiring strip that runs along the bottom of the screen and if it touches the housing it will cause interference/flicker. All I did was remove the two bottom screws and install them in the very BOTTOM holes to lift the screen off of the screen housing. No more flicker! Makes me wonder if maybe some of the laptops off of the shelves might need to be checked. A lot of issues about HP and flickering screens on google. Hope this helps.

Why your computer screen flickers and goes black?
My monitor flickered, informed me to check connection, and then went black. If you unplug the monitor from the computer and it goes black then it's not the computer or malware....it's the monitor going out. I bought a new monitor and everything is working fine again.
