Thank you for writing to us!
Firstly check if you can drain all the excess power from the system .
Check if you are able to run the LCD BIST .
1. Turn the computer off.
2. Press and hold the D key while pressing the power button. This will start the Laptop LCD BIST.
3. The screen will display multiple flashing colors. Look for lines, distortion, or any other video issues you have observed.
4. The laptop will restart when the test is finished.
Kindly private message the service tag to the system .
