In this video, I repair a broken TV antenna / RF connector port directly on the motherboard using a simple, budget-friendly DIY method.

Instead of waiting for an expensive replacement connector or replacing the entire TV board, I modify an inexpensive antenna extension cable and solder it straight to the grounding and signal points. This creates a flexible "pigtail" connection that makes wall-mounting much easier without risking breaking the port again.

Whether your TV antenna port snapped off during wall mounting or broke from tension, this step-by-step repair guide walks you through the teardown, diagnosing connection points with a multimeter, and soldering under the microscope.
