PS-1 smoke boards can be repaired. As long as you did cook the PCB so bad that traces disappeared or burned the fiber. If you put a picture up, may have the top board assembly. Worst case is the stack can be removed from the bad PCB if it is damaged. Swedged and reinstalled in another. Epoxy is your friend, if really damaged. Normally though, just rebuild the unit. I can do it if your not sure what is wrong and some of the electronic parts are damaged. G

The motor works fine when tested independently of the board, so the board has to be the issue. I can't tell which component

of the board failed, but some of the solder points in the right picture look burned. Maybe that has something to do with it.
