Default STK413-20 amp chip problem

Should I attempt to replace a bad STK413-20 and a STK412 in a Kenwood KRF 8030 surround sound amp. Both chips were overdriven and has 18vdc at all the outputs, bad power supply? I am hesitant due to the surface mounted devices on the main board. If any of the surface devices smoked I dont feel its worth the troubleshooting effort to find and replace these. Any experiences out there?
