Firmware for an LG 43-inch television fitted with the TP.MS3463S.PB765 main board, supplied in a 9.19 MB RAR archive. The TP.MS series boards are universal TV mainboards based on MStar chipsets, and the PB code usually denotes the panel or configuration. The dump is used to reflash the board's SPI flash when the set is stuck on logo, boot-looping or has no picture. Back up the existing chip first, confirm the board and panel match, and check the image size equals the flash chip capacity.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
