19876-2 PD controller firmware

Hi everyone, I have a motherboard from a DELL Precision 5760 laptop, part number 19876-2. One of the PD controllers died. I bought a new one in China and installed it, but now the board won't boot, even though the PD controller switches to 20V mode. Is there a way to restore the PD controller firmware? Is there a miniprog for flashing Cypress?
