USB firmware package for the MXA_4500S universal TV main board, set for a Full HD panel and a 680 mA backlight current. The RAR is about 854 MB and should be unpacked before use. Typically the files are copied to a USB stick and loaded through the board's update routine. A wrong backlight current setting can overdrive the LED strips, so check your panel's rated current and resolution first. Confirm the board marking matches, and keep the original software available if you can.
