BIOS firmware for the Toshiba Satellite L755 built on the Quanta BLB platform, motherboard DA0BLBMB6E0, in a 1.71 MB rar. Writing this image to the SPI flash with a programmer can recover boards with corrupted firmware that power on without display. Quanta uses the DA0 prefix followed by project and revision characters, so compare the full code on your board, as related BLB boards differ. Read and save the existing chip contents first, and confirm the image size matches the chip before writing.
