Replace the sub board on a Samsung Galaxy Tab S11 (SM-X730, Wi-Fi model) with this genuine Samsung service pack part, code GH82-38302A. This is an original Samsung component supplied brand new — the lower interconnect board (sub PBA) that links the mainboard to the tablet's lower assembly, carrying the charging and data path along with connector interfaces.

Sub board faults are a frequent cause of charging and connection problems that persist after a flex or port check — commonly following liquid ingress, board corrosion, or damage from a previous repair. Replacing the sub board restores the connection path with a straightforward board swap rather than component-level rework.

Common Faults Resolved

• Not charging or intermittent charging with a known-good charging assembly
• No USB data connection or accessory detection
• Connection faults after liquid damage or corrosion
• Faults introduced during a previous repair
• Intermittent connection between the mainboard and lower assembly

• Diagnose first: confirm the fault sits with the sub board rather than the flex, battery, or mainboard before replacing.
• Disconnect the battery before fitment to prevent short circuits.
• Board connectors are delicate — seat the board-to-board connectors carefully and do not force them.
• Replacement adhesive required to reseal the device after fitment.
• Bench-test before sealing — verify charging and data function before reassembly.
