If it's the screen, cable to/from the screen or the motherboard since repair costs tend to run more than half the replacement laptop. I see the screen (found by google) to be 20 bucks so you must decide to try this.
While adjusting the screen the left upper side of the screen went white and rest of the laptop works perfectly fine.
The laptop is ASUS X555L, Is the screen broken ?
