I would start with a board HW check:
This how to start and display the online HW test (no service interruption):
STR HWOLTST and DSP HWOLTSTRESULT
This is how to start and display an offline HW test (there is service interruption):
STR HWTST and DSP HWTSTRESULT
There is a chance that the HEI port, HEI interface, or HEI cable is not correct and the board itself is fine.
