Laptop screen flickering CQ50-110US

Please explain the events that lead up to your screen flickering ... in detail, from the time you turn the laptop on. Does the splash screen flicker?

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.

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.

Hello there,
The reason the screen flickers is simply because the module of the laptop is faulty. The module is what connects the screen to the main board, it is like a flex for the screen. Once you can have it replaced, the screen will stop flickering.

First you will need to determine if there is a problem with the laptop screen or the video card.

Plug in an external monitor to your laptop and use your laptop, if the screen on the external monitor flickers the same way your laptop screen flickered then there is a problem with the video card and you will need to repair your laptop. This is considered a major repair because the video card on the laptop is usually embedded into the motherboard and will be expensive to replace.


If the screen does not flicker then the connection from your laptop to your laptop LCD display might be loose. You will need to remove the cover of your laptop and make sure the connection is firm, as well as make sure there is no damage on the connector or wires.

Hope this helps.

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

flickers..sounds like a problem deeper than the screen..what kind of pc laptop are you using. and please provide the model number?

Hardware, sound like the cable that attach to LCD panel was losing...

Sounds like the driver board for the backlight is going bad...is there a spot on the screen part of the case ( usually at the bottom) that feels much warmer than the rest?
