TV main board firmware labelled MST181, version 1.3.03, build date 30 August 2012, with V and HY suffixes the name leaves unexplained. Boards with an MST prefix are generally built around MStar scalers used in many budget LED TVs. The image is 2.72 MB, which does not match a standard flash capacity, so treat it as an update or partial image until verified. Before writing anything to the SPI chip, read and keep a backup of the existing contents and confirm the board marking matches.
