Introduction
HDMI ports are essential for connecting televisions to devices such as set-top boxes, gaming consoles, streaming devices, laptops, and home theater systems. When an HDMI port becomes damaged or stops functioning correctly, users may experience signal loss, display problems, or complete connection failure. Many customers contact a Sansui TV Service Center when their television cannot detect connected devices or displays intermittent HDMI-related issues.
Professional diagnosis helps determine whether the problem is caused by the HDMI port itself, the connected device, the cable, or an internal television component.
