DELL e5510: suddenly whenever I turn on my laptop it will just flash with lines that looks likes threads of clothes? then after a few seconds the screen is just black and full of colored vertical lines (...


Here is a hardware test you can run to test the video and lcd screen. That came with your laptop

Diagnostics before windows using the F12 Diagnostics
* Reboot and press F12 to enter the Boot Menu
* When the boot device list appears, highlight Diagnostics and press Enter
* The computer begins to run the Pre-boot System Assessment, a series of embedded diagnostics that perform initial testing on your system board, keyboard, hard drive, and display
* If the Pre-boot System Assessment completes successfully, you receive the message Booting Dell Diagnostic Utility Partition
* Press any key to continue
* Press any key to start the Dell Diagnostics from the Diagnostics utility partition on your hard drive
* After the Dell Diagnostics loads and the Main Menu screen appears, click the button for the option you want to run -
Express Test = Performs a quick test of devices. The test typically takes 10 to 20 minutes and requires no interaction on your part
Extended Test = Performs a thorough check of devices. The test typically takes 1 hour or more and requires you to answer questions periodically
Custom Test = Tests a specific device. You can customize the tests to be run
Symptom Tree = Allows you to select tests based on a symptom of the problem you are experiencing
* When you have finished running a test, close the screen to return to the Main Menu screen. To exit the Dell Diagnostics and reboot the computer, close the Main Menu screen


during the test it will BEEP ! it is asking you if colored bars are displayed. if the bars look ok then your screen is fine but if during anytime of this test and you see the distortion you described then its the LCD screen or LCD cable

hope that helps

Dark Grey Vertical Bar


1. try connecting laptop to an external monitor and check if this vertical dark gray bar appears. if yes it means video is the problem. you need to boot in safe mode then uninstall the video driver. boot to notmal mode then download and install the latest video driver. if still same problem then replace video card. if video is built in with motherboard you need to replace motherboard.

2. when the vertical dark gray bar did not appear in the external monitor then it means issue is with the LCD panel. Do this turn off laptop. press and hold D key then press Power button at the same time or Press and hold on the Fn key then Power button check if the test will run. Color displays full screen when you keep pressing on N key when the colors appears check the vertical dark gray bar if still exist in the test, this means LCD panel and LCD cable needs to be replaced.

Occasional colored vertical lines on the screen at startup


base on our experience.... you are looking at a possible screen problem. Is it serious? yes as the screen replacement costs almost half of the total cost of the laptop.

but no harm trying this

1. remove the screws from the LCD bezel, remove the screen
2. detach the cable and reinsert them all both the inverter and the flex cable.

inverter is the circuit usually located at the bottom of the screen and the flex cable is the ribbon that runs from the laptop to the back of the lcd.

reseat them and see if your display improves
