Diagnose A Dv5000 Laptop Screen

The Pavilion DV5000 is a PC laptop computer model manufactured by Hewlett-Packard. Its LCD screen is powered by a back-light and a screen inverter board. Over time, it is possible for your laptop screen to become damaged or even to fail. Pinpointing the exact problem with the screen will help you determine if you can repair it yourself. Even users with moderate computer knowledge can use these steps to diagnose a screen problem.


Instructions


With a Dark Screen


1. Turn on your laptop, using a wall outlet power supply rather than the laptop's battery. If the screen is completely dark for no reason, or if the images on the screen are pixelated or smeared, there could be a problem with the screen.


If the screen shows pixelated/color-smeared images, a screen replacement may be required. But if the screen is dark, proceed to the next step.


2. A dark screen usually means a bad inverter. To examine this possibility, turn off the computer and unplug it. Use a Phillips screwdriver to remove all the screws on the plastic frame around the LCD screen.


3. Pry the plastic frame off the unit to expose the rectangular inverter board mounted below the screen.


4. Unplug the cables that attach to the ends of the inverter board and remove the screw holding the inverter board in place.


5. Remove the inverter board and replace it with a new one (available from a computer supply or electronics store). Replace the cables and screw. Inform the store you are looking for an LCD screen for a DV5000 laptop. Provide the user manual and model number if possible. If a larger retailer does not have your screen, you may be able to find one from a local PC laptop repair shop.


6. Replace the bracket screws, plug the inverter wires back in and replace the screen frame. Power on your computer in order to test the screen.


With a Pixelated Screen


7. Turn off your computer and remove the screen frame to expose the inverter board.


8. Unplug the cables that connect to the ends of the inverter board.


9. Remove the screws from the brackets on either side of the screen and tilt the screen forward to expose the ribbon cable behind the screen.


10. Unplug the ribbon cable that connects to the back of the screen and remove the screen from the brackets.


11. Fit a new screen between the brackets and plug the ribbon cable into the port at the back of it.


12. Replace the bracket screws, inverter cables and screen frame. Power on your computer and test your LCD screen.
