This issue points to short-circuited SCRs or thyristors on the power stage. When these components fail from heat stress or overload, they often default to a permanently closed state. This bypasses control logic and feeds raw, unregulated voltage directly to the motor output pins. You will need to desolder the power semiconductors or replace the controller board.
