Light Coil 3X3 For TECNO Infinix 10Pcs

Backlight complaints are one of the most common jobs that land on a GSM bench, and more often than not the fault traces back to a worn or dry-jointed boost coil rather than the LED strip itself. This 3×3 Light Coil is built for exactly that repair point. It sits in the backlight boost circuit and helps step up voltage to drive the display's LED array, so when a phone shows a black screen with sound and vibration working, or the display flickers and dims under load, this coil is one of the first suspects on the board. You get 10 pieces in this pack, which matters more than it sounds. Backlight coils are tiny, they get lost easily during reballing or board cleaning, and running out mid-repair means stopping a job to source one piece. Keeping a stocked pack on your bench means you go straight from diagnosis to fix without a parts run. The 3×3 size is shared across a wide range of boards. Technicians working on Tecno and Infinix devices will recognize this coil from backlight boost circuits, and the same footprint turns up on Huawei, Xiaomi, and Samsung boards as well. Because Transsion brands (Tecno, Infinix, Itel) frequently reuse board layouts across budget and mid-range models, this coil covers a large share of the dead-backlight jobs you'll see coming through a typical Pakistani repair shop. On the bench, the failure pattern is usually one of two things: either the coil has a cold solder joint from age or heat cycling, causing an intermittent backlight that comes and goes when you flex the board, or the coil itself has degraded and the backlight stays completely dark even though the display shows a picture under flashlight (a sign the panel and driver are fine, and the fault is upstream in the boost line). Reflowing or swapping this coil resolves both cases in most boards where the backlight IC and LED strip test good. Handling is straightforward with a hot air station and fine tweezers. The 3×3 pad size means you don't need an oversized nozzle, and reflow temperature stays low enough that you won't disturb neighboring components if your airflow is controlled. For technicians running a UFS or eMMC-heavy bench alongside hardware repair, this is a quick component-level fix that doesn't require chip-off work or data risk, which makes it a fast, low-risk repair to offer customers.This pack fits naturally into any board-level repair kit. Pair it with a hot air rework station for the actual reflow, a PCB holder to keep the board steady during work, and a microscope if you're working on smaller multi-layer boards where solder joints are hard to inspect by eye. Technicians who regularly service Tecno and Infinix devices, or run a general mobile repair shop where these brands make up a large share of walk-in traffic, will find this a practical stock item rather than a one-off purchase.Because backlight faults are recurring across a technician's daily workload, keeping this coil in stock reduces turnaround time on one of the most frequent complaints you'll hear from customers: "screen is on but I can't see anything."
