No HH RIDE CRASH, Help Needed

Hello, i just finished my build, and i have some issues;..First i have no sound for the eeprom's instruments...
All other works well (just have a strange sound for the hi tom...but will check later).
I m unable to check / swap eeprom, because none of the eeprom's instruments works...voltage is ok on all eeprom slot...
Is it a way (without oscilloscope) to check if the eprom's are ok?
i made the mistake to power the nava with the MUX_SH boards plugged and also the eproms plugged, seems to have some issues on my mux-sh build (some warm/little hot smell) , could be a reason to burn the eeproms? Or no interacts between them?
Thanks and sorry about silly questions...
I don t know where to search first ...
Many thanks!

Almost certain it’s the left side MUX pcb. Try pop it and test again..
