Samsung LED TV hit by storm power surge

Power surge shut down my cousin's Samsung UN46C6300SFXZA LED TV. Nothing visibly blown on on power board (no fuses blown, no bulging caps, no carbon or burns on front or back of board), checked components with DMM & oscilloscope's curve tracer and all seems fine. Except standby light is on, with 5v present but no other voltages at connector points (from list). Tried jumping 5VSTBY pin with Power ON/OFF pin and still no other voltages present. Does power board get a return voltage from main to turn on TV via 5V detector circuit? Doesn't seem logical that main board could be damaged before the power board, but I'm new to digital TV troubleshooting. Thanks for any and all tips.
