Questions about this item

How is the 402WG LCD ribbon cable routed through the 15.6 Latitude E5520 hinge assembly?

Thread the flat flex cable along the hinge channel with the gold contacts facing the motherboard connector, then seat it fully before locking the ZIF latch — skipping the latch click is the step most people miss.

When will the 402WG ribbon cable on a 15.6 Latitude E5520 typically need replacement?

Replace it if the display flickers, shows vertical lines or loses backlight after repeated lid cycles — those symptoms mean the flex traces have fatigued from hinge movement.
