TSUM scaler firmware for the LG W1941S monitor in its single-LVDS panel variant, version V102, checksum 4FD9, date code 090922. The name makes clear this build is for main boards driving a single-channel LVDS panel, so it must not be mixed with the dual-LVDS release. It is flashed to the main board SPI memory with an external programmer to cure no-picture or boot faults. Dump and keep the original chip first and check the panel interface on the actual set before writing.
