    Old tantalum capacitors sometimes short and explode. Probably nothing wrong with the board. If supply voltages are correct, just install a new capacitor. Maybe it would be a good idea to replace all tantalum caps.

    That explains why my schematic shows C45 as a 22pF

    Get 35V caps when ordering.
