LE55B650T2WXXH mainboard swap issues

I bought 10 years ago 2 B650 series (37" and 55"), the mainboard of my 55" is dead yesterday and I used the mainboard from my 37".
The tv runs but I don't have sounds with all HDMI if I use 1080p, it works only with a 720p source.

Is there special settings in the service menu I have to enable or I need to use an other motherboard?

BTW, my plan is to buy a new motherboard for the 55", I found a lot of BN94-02583P but I want to be sure it is the good one ...
