mbsid_interconnection test problem

Hi all. I just soldered all the PCBs from Mike's shop, tested all DIN's and DOUT's, CORE - all is working fine.

But with MBSID v3 there is a problem with interconnection test.

 

During the test i only can get result for #CS pin which changes from 0 to +5v when appropriate key is pressed.

But no results from A0-A4 and D0-D7 #RES pins.

 

I thught it may be bad 74HC595, but installing new 595's was no effect at all.

Can it be PIC problem?

 

All cables and other PCB solderings was checked ten times - no errors.

All power pins shows the +12 and +5 where it must been.

 

Any idea?

 

edit: after testing separately 595's i found that all 595's are good and working with A0-A4 and #RES, but then in other place (connected to D0-D7) is not working, and when is placed - the first 595 is not working too.

 

edit2: accidentally, now is working all 595's. I think it was bad socket connection. Sometimes it need to be written about the problem, for kicking myself to solve the problem.
