Dave, when some of the functions on our Thomas Payne furniture didn't work I looked at all of the Molex type plugs underneath. I found that on some of them the pins had pushed in, or out, and we're not making contact.
You will need to pull each plug and inspect each half.
I was able to push the contacts back in place. They are supposed to be held in place by little barbs.
Let us know what your final fix was.
Peace
Dave
