Common LCD screen display problems Creative IT can resolve
Laptop LCD screen has a faint image or is very dark
If there is a very faint image it is possible that the Compaq Presario CQ56 laptop's LCD screen lid close control switch is stuck in the closed position. In this mode the backlight stays off, even with the LCD lid open. The good news is that you may not need LCD screen replacement as this fault is often due to a faulty inverter which can be easily repaired or replaced.
Laptop LCD screen is solid white colour or garbled
This indicates that you have a problem with the Compaq Presario CQ56 laptop’s LCD screen or the LCD cable connection.
Identical vertical lines all over the LCD screen as soon as it is turned on
These lines can be red, blue, or white and may appear as fine lines or wider bands. They are usually due to a faulty ribbon that connects internal the LCD panel
Horizontal lines appear on the screen
When horizontal lines appear on the laptop screen the fault may be poor connection between video cable and LCD screen, a faulty video cable or LCD screen failure.
Half the screen shows no image or appears black
The screen is defective and LCD screen replacement is often the only solution for this.
When this occurs it is likely that the backlight of your Compaq Presario CQ56 laptop’s LCD screen is faulty and needs replacing.
Diagnosing and repairing LCD screen faults
The most reliable way to diagnose display issues is to connect the Compaq Presario CQ56 laptop to an external monitor. If the external monitor image is fine, then the fault lies with the Compaq Presario CQ56 laptop’s LCD screen itself or some component related to it such as a backlight, inverter or video cable. Depending on the fault, repairing the defective component or LCD screen replacement will resolve the problem.
When the same display defect appears on both monitors – Compaq Presario CQ56 laptop’s LCD screen and external screen - then it is almost certainly due to a defective graphics chip. On some laptops the graphics chip is integrated into the motherboard, on other models it’s a separate module. Creative IT tries to repair or replace motherboard components whenever possible as it is more cost effective than replacing the entire Compaq Presario CQ56 motherboard.
Creative IT’s graphics chip repair technicians are highly trained and able to carry out mainboard component repair on your Compaq Presario CQ56 laptop. Overheating can eventually loosen the graphics chip connection to the motherboard of your Compaq Presario CQ56 laptop.
