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.

Flickering screen


Try an external monitor to the laptop and see if it flickers. If it does, more than likely your video card is going bad. If it does not flicker on the external monitor you probably have a loose video cable or lcd inverter cable. Go back inside and remove the 2 cables that go into the LCD Inverter that sits at the bottom of the LCD Screen, then plug them back in. Then unplug the video cable at the top behind the lcd screen, plug it back in and secure it with a piece of tape right where the two connections meet.

How do I fix the constant flickering of the screen?


Hello,

Take the lcd assembly apart, and disconnect and reconnect the ribbon cable on the back of the lcd. Also disconnect and reconnect the other end of that cable. If that doesn't fix it, disconnect and reconnect both cables that go to the inverter board (it's the small circuit board inside the lcd assembly- example in picture below). If still no good, then you probably need a new inverter board. Call HP and get a phone number for one of their parts suppliers. Inverter boards are cheap ($10-$20). Even if it doesn't fix it, it doesn't cost much to try. If still no good, then take it to a service shop.

Hope this helps!

Screen color is messed up screen is like purple tint


Try to bring it to a shop. The plexcable of your notebook is not properly attach causing it to turn purple. Use the warranty of your notebook and bring it to the shop to check or to repair.

My lcd screen on my new msi cx700 keeps flickering and going black. if i press the top corners of the screen bezel the screen returns to normal.Could this be a bad screen, backlight, inverter, something...


This may be due to the inverter board found behind your lcd panel.
Take it apart & solder the two sides of the coil found on the inverter board. This loose solder is caused by heat.

The screen is white >>>


Your inverter board is OK otherwise you will not get any light on the screen, there is only one inverter board, Check the flat ribbon cable connected to the LCD panel (locate behind the LCD panel), when this connector comes off you will get white screen.

Flickering and Shaky Screen


The LCD backlight is burning out or the LCD inverter board that controls it is going bad. Backlights are cheap. Must take apart LCD screen assembly. Inverter is a bit more expensive. Definitely fixable.
