Toshiba 50L1450U Won't Power on, Power Board seems ok. No light.

I just picked up this Toshiba 50L1450U to repair. It does not power on, there isn’t even a stand by light. When I check the Power Board I see no issues, the voltages match the markings and the voltages follow through to the main board connector. Is this indicative of a bad main board? I’m not even sure what to check on the main board to diagnose.
