Asus X550 Touchscreen Laptop Screen Replacement – Fulham SW6

This laptop had a temperamental LED screen. It worked occasionally. We suspected either a faulty screen cable or a faulty screen. We took the top lid apart and checked visually  the cable for any damage. The cable seemed to be OK. We replaced the screen and the problem disappeared. Faulty screens sometimes do have strange symptoms but it is vital to carry out step-by-step diagnosis before replacing the LCD/LED screen.
