Main 12v PWR to GND will be just a few kohm due to bias resistors, for example the path through R13,14,15,16 in the upper left of the schematic.
PA-PWR to GND resistance will gradually increase (not decline) as C157 charges up, Q15 is off with no power applied and the current has nowhere else to go.
Your board is probably just fine.

measured resistance between positive and negative at PWR 1 about 3.13 KOhm
measured resistance between positive and negative at PA-PWR 1 about 40 MOhms, then declines
measured resistance between positive terminal at PWR 1 and positive terminal at PA-PWR 1 about 15 MOhms then declines
measure resistance between negative terminal at PWR 1 and PA-PWR 1? ? 0 ohms
