I think I might have it figured out. The wire connector going into the IR sensor board has some of that oily stuff in it, and it's conductive. With the harness removed from the TV and nothing connected I should see OL when probing different wires, but instead I'm seeing between 1MΩ and 20MΩ. I'm going to clean it up and see what difference it makes.

Solved! It was the conductive goo that dripped into the connector. Pulled all the wires out of the connector and cleaned everything real good, now it works perfectly again.

I just knew it had something to do with that goo.

So, there were 3 bad resistors on the key control board. One was a 20k, two were 3k. I was able to find a 20k on another board. Couldn't find any and 3k resistors, but I did have some 1.5k through hole resistors. As you can see from the pictures, I made it work with what I had. My girl will be quite happy to get this back tomorrow. The only bad thing is she wants to keep the 32" Seiki I loaned her. I should have seen that coming.
