TAC 32 1921 fault - 08/24/18 06:14 PM
TAC 32: After a recent power bump we found all the ( BAD) leds lit on the IOD board. The CPUA board lcd is still usable. It appears that the cpua and Ido boards are not communicating. The error code list indicates a 1921 fault and that one or both boards may be bad. I Just thought I’d touch base here before throughing in the towel. Any help or thoughts would be appreciated. Thanks

You can use an XE2 if that helps in your search.
