Just checking if this topic is dead...

Can someone give me some ideas.
Bm54 is plain dead, doesn't communicate with navcoder, checked all voltage regulators, seems like voltages are as should.
29f400, 24c64 and 27lv010 are reprogrammed.
Could it be that c161 is dead?
Found before cold solder joints around the ground shielding - which wasnt the case for this defect.
