ZIP archive of 3.69 MB whose name points to a TV model LT-50N640SD with the CV9202H mainboard; the suffix bsm is not explained. The contents are not listed, but such packs typically hold a firmware dump or service files for the main board. Before using it, open the archive and identify each file and its target chip. When reprogramming a TV board flash, read and back up the original memory first, and make sure the dump size matches the chip capacity and the board marking matches CV9202H.
