It was a NO-GO regarding the PFD configuration module test this morning. After all that work, the new chip replacement apparently was not the answer to the error message. So what's next. Disassemble the panel again & this time swap out the 4-pin connection harness. The wiring of the module is tiny & subject to fault. So, this is going to take some time...
The upside..? Well, at least I am now better understanding how to remove & replace avionic components in a fairly efficient manner.
