Two things send me the xtrainfo I can tell you what it means. Also look on the lower left side off the CRIPHNA board and see if resistor R176 is burnt. I have replaced 2 of these boards due to that resistor being burnt. it provides "door power" I had many calls with door faults then finally saw the burnt resistor. If it looks black or discolored poke it with an ink pen and see if the door power led flickers or goes out. Pretty expensive replacement for a very cheap part.
