Flickering screen on laptop - HP Computers & Internet

    Fn42,



    when the screen flickers do you mean it goes from being on to off so to speak, and if so when the screen is "off" can you see anything on the screen if you say shine a torch up to it.



    If this is the case it could be a problem with the backlight on the panel.



    Regards

most likely a loose connection if it is flickering.. if there are red squiggly lines usually means driver issue.. and if there are blue banding lines, typically means the chip is overheating/desoldering.

Upper sise of screen flickering problem


Technology b> A laptop's display assembly consists of an LCD panel, an inverter board and a backlight lamp. The inverter board supplies power to the lamp which lights up the LCD screen as it generates images. Light from the lamp is then uniformly distributed over the panel to create images. b> Cause b> Flickering is commonly caused by a damaged or malfunctioning inverter. Because a faulty inverter is not able to supply adequate power to the backlight lamp, the screen goes dim each time the backlight loses power. In some cases, flickering may also be caused by a faulty connection between the inverter and backlight lamp. Diagnosis b> Resolving a laptop screen's flickering problem entails correctly diagnosing the problem and replacing the faulty component. You may diagnose the problem by hooking up the laptop to an external display unit, such as a projector. If the external display has the same display problem as the laptop's LCD screen, it is indicative of a motherboard or video card problem. If the external unit displays bright, crisp images, the problem is probably caused by the backlight or inverter. b> Solution b> You may repair a laptop screen's flickering problem by replacing the inverter board or backlight. Order parts from a trusted supplier and replace the component by referring to your product documentation.

The screen flickers periodically without any reason. If i giggle the screen or pull the screen down the up it staops.


Hi

The flickering happens because the flex of your laptop is getting weak.

The flex connects the screen of a laptop to the motherboard it is through it that data is passed to the screen.

It is found in all laptops and the more you open and close the laptop,it gets weaker and weaker.

The best thing to do to stop the flickering is to change the flex.You can also loose the laptop,remove the flex and fix it back properly but that may not stop the flickering permanently.

Note;if you cant loose the laptop yourself please get an expert to do it for you

Thank you for visiting fixya

Acer Laptop Screen Flickering


The flickering screen indicates that it is a backlight problem with either a faulty inverter or inverter connection problem. The inverter is usually located at the bottom edge of the LCD screen, and may have one or two connectors (one for the video info. and one for the inverter power or a combined connector) attached to the motherboard under the case near the top edge of the keyboard near the hinges. Reseating these connectors may solve your problem.

My laptop screen is flickering


That could be ths connector that connect the LCD to the Motherboard in the laptop. Ive seen something similiar wherein i took down the screen, cleaned up the connectors and it worked like new...... for a few weeks then it went back and started he flickering again. We finally fixed the problem by replacing the screen. Apparently the connector behind the screen was giving trouble. Have someone check the cable from your LCD to the board but I think you might need to fix the connector or replace the LCD screen. Regards, babb
