This is a fault with the display driver. The only possiblity is to check if there is any loose connection in the lines leading from the mainboard to the display through the hinges.
If by checking the line disappears then the fault is confirmed as this harness can be defective.
otherwise the drive IC can be faulty.

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
