Raw 4.00 MB BIN dump labelled SUPRA 55 with a 1920x1080 resolution, most likely firmware for a Supra 55-inch TV main board with a Full HD panel, though the name gives no board number or chip. Such dumps are written to the SPI flash with a programmer when a set is stuck in standby or boot loops. Confirm the main board model and panel resolution match, read the original chip first, and check that the flash capacity equals the 4 MB image size.
