3a fuse is where I assumed

There’s 12v going to the board ....so that points to bad board?

No power between j4-j10

Display has no power on a dometic rm 3663 fridge.....I’m kinda lost to what to test next here is what I have done chk 12v terminal block for pwr ✅ chk 110 ac ✅ chk 5amp fuse ✅ chk 3 amp ✅ by passed control board .......heating element heated fridge temp dropped to 33 degrees in few hours chk displayed connection and all connection for good connections am i right to think replace display circuit board?
