So is the 24VDC going to both inverters?

Yes.

Here's the pic of the bottom/solder side of the power supply board. I reassembled it an took some voltage readings on the 24vdc pins that go to the inverter boards. I DO NOT have any DC voltage on any of those pins.

One thing is not clear to me is that you are saying you have dim backlights but since you do not have the switched 24V (present when PS-ON is present) so I cannot see how you will have backlights at all.
Can you please verify that again?

Yes. The two cables that are unhooked in the 2nd pic. One cable for each inverter board. If you super size the pic you can see several pins (5 per connector) labeled 24v. Since I have no 24vdc going to both inverters, I definitely have a power supply problem. Another problem I've found is someone has previously tried soldering this power board and may have done more harm than good.

The last few times I’ve tried powering on the TV I did not see any back lights. Initially I could barely see the Akai logo on startup.
