Thanks for the tips.

In the Sony's current condition, I'm not able to perform these tests. With the main board plugged into the power supply, within seconds after plugging the unit in, the standby voltage drops to .5V. This only happens with the main board plugged in otherwise, it's at 3.29V. Lightning does strange things to electronics.
