RAR archive of firmware material labelled COF details for a Sunny branded unit, with BSL in the name, which most likely refers to a television panel or board variant. The name gives no model number, so the exact contents can only be confirmed after extraction. COF usually means chip-on-film, the driver tapes bonded to an LCD panel, so the pack may relate to panel timing or T-con data. Before writing anything to a chip, compare the board and panel codes against your set and keep a copy of the original contents.
