I would suggest you to connect an external monitor and check if you face the same issue. You may try the following steps.

Check in BIOS:

• Power off the computer
• Restart the computer, tap 'F2' key on the Dell logo 4-5 times
• Once you are on the BIOS screen, check if you face the same issue

Alternately, run the LCD BIST. To run the LCD BIST (Built in Self-test):

• Power off the computer
• Press and hold the 'D' key on the keyboard while pressing the power button, then release both at the same time.
• This will initiate A grey screen, then Red, then Blue, then Green, then White
• Please check for the green vertical lines

Please reply if you have any questions.

Thank you. I get it. But the topic has not remove ... I check and write the result. ... and then be able to remove topic.
