JCID S35C Motherboard Test LCD for iPhone 13 to 15 Plus

Testing a repaired board on the customer's own screen puts that screen at risk, and keeping a spare display for every model gets expensive. The JCID S35C is a single test LCD that connects to six iPhone models through converter cables.

The S35C is a motherboard test screen from JCID for the iPhone 13, 13 mini, 14, 14 Plus, 15 and 15 Plus. It connects directly to the logic board, lights up a real iOS interface and responds to touch. The package includes the S35C screen and six converter FPCs, one for each model.

When the S35C pays off

• Telling a damaged screen from a faulty board when there's no image.

• Testing a board after repair without risking the customer's display.

• Checking touch faults that may come from the board.

• Recovering data from a phone whose screen is broken.

Model coverage

It covers the standard and mini or Plus models only; the Pro and Pro Max versions aren't listed. Match the converter FPC to the board before connecting it, as each one is model-specific.

Handle the converters gently, since repeated plugging is what wears them out. Keep the S35C protected in a case between uses, and disconnect power before swapping converters.
