I would recommend this one as your first action. In many places the POCO will conduct safety inspections free of charge. Whether or not that service drop is the homeowners responsibility or not varies (something to ask while you schedule the inspection) but if you are lucky the POCO will fix it at their own expense (eliminating the debate with the seller about who is going to pay for the fix).
