I just removed my old main board from 40C6510 and tried to replace with 55C6710. After installing the new board, no picture at all. Only sounds come and backlight. Any suggestion how to make it work?
Edit: Seems LAN works too. It get DHCP...
Edit2: Issue fixed. Please close.

lvds wasn't connected well... Just replug the cable and all is OK. I can confirm that board from 55C6710 works well on my 40C6510. Now have to root the device...
