Here is a picture of the main board on this. I am hoping one of the empty sets of terminals allows for recovery options. I would like to get this receiver going again so I can finish testing it.

I see an empty 4 pin connector in the main board under the 4 pin U15 IC. Maybe you could jtag from there. Looks pretty similar to others. I think the MicroHd have something similar and people have jtag thru there.
