HiSense 55H7B/Sharp LC-55N7000U main boards interchangeable?

[DXseekerMO]

I recently ordered a main board #189557 for a HiSense 55H7B and was sent a main board for a Sharp LC-55N7000U #192209. I sent it back and asked for the right board. They turned around and sent me back the Sharp main board saying it was the same as the HiSense #189557.

Am I missing something here? Does anyone know if this is maybe a dual-use board with the HiSense firmware upon it and I just need to call it up from the service menu or something?

Thanks in advance.

You would need the Sharp remote at the very least.

I have a remote for a Sharp that does work. Is there HiSense firmware in there that you know of?
