ZIP archive named after the BD9261EFV, a ROHM integrated circuit, 1.61 MB in size. The name does not say what is inside, but it most likely contains the datasheet or reference material for this chip. In TV repairs this part is commonly found in LED backlight driver circuits, so the pinout and application circuit help check boost and current control stages. Extract the files and compare the marking and package on the board with the documented part before replacing or measuring it.
