Sanyo DP42848 No Sound/Picture not the inverters

Re: Sanyo DP42848 No Sound/Picture not the inverters

I found a BL_ON that runs to the Main Inverter board, but it comes from the Main Board, and not the Power Board. I'm guessing it's the right one, as the only other things that come close are a BL_SW and a BL_ADJ which are all connected at the same place on the wiring diagram.

What should it test as if it's working?

For a bit more clarification, the wiring diagram shows 5 points on the K8L where the BL_ON is located, but the K8L on my mainboard has a plug with 5 holes, but only 2 of which actually has a wire coming out of it. I've checked all the versions of the service manual listed above and its the same in each.
