Well you have stumped me, I cannot think of anything else.

It would be very, very rare that 2 circuit boards would have the exact same fault.

I am going to put this into the tech section may be I missed something or someone else has run into this and knows the fix.

You are welcome

This one was a bit of a hair puller for a while.

I am very happy to see that your perseverance was rewarded with success.

And thanks for getting back to us. Now when others search for a similar problem they will see what actually worked instead of just suggestions about what could be the cause.
