HI, the SM tells;The rejection of communication by controller during start up possible cause Blue back display.
(possibility: defection of Panel board, controller board, connection cable, etc,...
was it a a white or grey background on the display?
did you upgrade with cf with door open; if Yes= > did the machine displayed every part of F/W ok or NOT FOUND.
my solution => HDD externally format, reload FW problem should be solved.
second solution= > did you took aout the display? => wrong cable in wrong connector in display pcb (One cable can go in to connectors)!!
please feedback!

upgrade the firmware. There was a case of defective Main Memory DIMM (SDRAM), so this might also be a

possible cause.

MEASURES:

- Check the contact between panel DIMM / socket. (Reseat DIMM)
- Upgrade the firmware or replace Panel DIMM. (Be sure to check FW combinations)
- Upgrade the firmware or replace Main DIMM. (Be sure to check FW combinations)
- Replace Main Memory DIMM (SDRAM).

This error may show up when there is poor contact between the Panel DIMM and it’s socket, or failing to
upgrade the firmware. There was a case of defective Main Memory DIMM (SDRAM), so this might also be a

possible cause.

MEASURES:

- Check the contact between panel DIMM / socket. (Reseat DIMM)
- Upgrade the firmware or replace Panel DIMM. (Be sure to check FW combinations)
- Upgrade the firmware or replace Main DIMM. (Be sure to check FW combinations)
- Replace Main Memory DIMM (SDRAM).
