Yaesu FTDX1200 Serial/CAT Port Died

I bought my Yaesu FTDX1200 new from Ham Radio Outlet in Atlanta in 2017.  I've had a great time operating the rig. I've never really run into any issues with it.  The rig has been connected via serial cable to a PC for rig control nearly the entire time I've had it.  One day, I opened my Ham Radio Deluxe software to find the error message "failed to read frequency".  I went through a lot of troubleshooting.  I tried another cable, a USB to serial converter, another PC, resetting the radio to defaults, etc...nothing restored the functionality. 

I contacted Yaesu and informed them of the problem.  The person that replied to my email was surprisingly vague.  I asked if the rig was under warranty.  They replied and asked for the serial number.  When I provided the serial number, they replied with another vague email and didn't tell me anything about the warranty.  I emailed a few questions and they replied with a one line message that didn't answer my questions.  At one point, I actually told them I was shocked at their lack of customer service. 

Eventually I got enough information to process a warranty repair.  I packaged up the rig (leaving a big mess in my shack), triple boxed it, and shipped it off to Yaesu in California.  I received a message saying they received it and then another a few weeks later saying it was going to be on the way home.  Once it was home, I opened it up and began setting it up.  Everything has been working fine again.  The thing that was odd was there was no mention of what repairs were made.  I'm sure they had to repair or replace something, but there is no documentation of it.

In any case, I'm glad the rig is home and back to normal.  The repair process with Yaesu was a little strange, but perhaps I was just having some anxiety about it. Overall the process was easy enough.  Hopefully, there won't be any further issues.  Per Yaesu, the rig warranty is 3 years from the purchase date...
