Common TV Symptoms Fixed

A faulty Wi-Fi/Bluetooth module can cause missing wireless networks, intermittent Wi-Fi connections, or Bluetooth pairing failures. These symptoms can also result from network settings, software, cables, or other components. Confirm the module is faulty before replacing it.

Fitment & Ordering Guidelines

Verify the white-sticker part number BN59-01407A, board number WCA731M, full TV model suffix, and version code against the original module and TV label. Do not order by screen size or model family alone.

Unplug the TV before servicing, use ESD protection, and handle the module by its edges. Avoid touching contacts and disconnect cables carefully. Use a qualified technician if you are unfamiliar with TV repair.
