No worries, thanks for the tips! We're pretty sure there's an issue behind the nav's control panel...back out to shoot more wires! Have a good sleep!

This is regarding APN-241 on C-130H2. Since we've gotten the APN-241, life has been good...until now! Initial write-up is error codes M-06/M-45. We replaced every LRU and have checked for continuity in much of the system. The problem is: BIT fails (LRU6/1A12 replacement codes)...the system seems to turn on completely (power is good) but the pilot control panel cannot take control and the pilot display unit will not display anything other than the startup screen. There is a PCPPWR? notification on the pilot display. When initially pushing WX on NRCP the PCPPWR? goes out but comes back within a few seconds. Has anyone seen this problem or something similar? We've been messing with this for a few days now and I'd really like to be done with it, especially with a UEI next week!! We have also contacted Northrop Grumman tech support, they're not a whole lot of help... Any input would be greatly appreciated. Thanks!!
