original woody

I have found my daughter’s original Woody from the first Toy Story movie . He looks great, string and mechanism looks and operates great but I beleive the chip or they may call it mother board ( I am not a Tech savey kind) where his voice comes from maybe dead . I checked it and wires, battery box with a volt meter all seems good however I get nothing from the green chip (mother board ) …lost on how to fix it ,if it can be fixed ??? love to give it to my grandson (Daughter little one) which I and may anyway but hope it can be fixed . I think he would have a blast with it like his Momma did .
