Light Coil for Apple iPhone 6S Plus 32GB

The Light Coil — or backlight inductor — on your Apple Iphone 6S Plus 32Gb is a small passive component in the backlight power circuit that stores electrical energy and releases it in a controlled, smoothed manner to drive the backlight LEDs at a stable current. Without a functioning Light Coil, the backlight circuit cannot maintain stable LED current — causing flickering, insufficient brightness, or complete backlight failure on your Apple Iphone 6S Plus 32Gb even when the Backlight IC and transistor are functional.

Both cause similar backlight symptoms — dark screen, flickering, or insufficient brightness. However a failed Light Coil typically causes audible high-frequency buzzing or coil whine alongside the visual symptoms, and the backlight may flicker at a specific frequency rather than randomly. A board-level technician can distinguish between coil and IC failure using a multimeter and oscilloscope on your Apple Iphone 6S Plus 32Gb.

Yes — the Light Coil is a passive component and is typically less expensive than the Backlight IC. Component-level repair technicians often test and replace the Light Coil first before moving to the IC in backlight repair workflows on Apple Iphone 6S Plus 32Gb, as it is the simpler and more cost-effective first step.

No. The Light Coil is a micro-SMD passive component soldered onto the Apple Iphone 6S Plus 32Gb motherboard. Replacement requires SMD soldering skills, a precision iron or hot air station, and magnification. This is a component-level repair intended for experienced board repair technicians only.

Yes — a 7-day replacement warranty against manufacturing defects is included. An unboxing video is mandatory for all warranty claims. Once soldered, the component is considered used and cannot be returned. For more information, check out SAHII's Return Policy.
