GTN750Xi not starting up when launching MSFS2020 and C414AW

[jnaslund]

Hi,

Had a problem with my PC and changed power board to fix it. It's been U/S for about 5 days.

Now when i run MSFS2020 and load up the Cessna 414AW, i can see the GTN750Xi panels as normal but they are completely black.
I have done all TDS updates i can think of but it's still no joy. 
GTN750Xi not starting up when launching MSFS2020 and C414AW.

Previously during starting MSFS2020 i could see a popup for TDS750Xi that disappeared. I think that is the root cause. For some reason TDS750Xi does not start together with MSFS2020.

Incidentally, after been U/S and i got my PC back up running again, i got some new Norton warnings that i have never seen before. Turns out that Norton has updated their software during the 5 days my PC was broken.

I have checked all quarantined files and none of the TDS files are there.
I checked the Norton firewall settings and this is what i see:
GTI                           Allow
GTN Xi Series trainer   Allow
GTNXi Flight Sim EXE  Allow
TDSGPS Manager       Allow

Not sure what to do. Need help!

Merry Christmas / Jan

Hello Jan,

As a first step, please reinstall the TDS GTNXi for MSFS 2020 from the TDS GPS Manager.
Then, with MSFS closed, start the TDS GTNXi from the desktop shortcut and click on the GTN750 Xi button, does the screen light up?

If it does not, then please send us via email this log file from My Documents: TDSGTNXiExeLog.txt
support@tdssim.com

Not to worry, we will get this issue sorted.
