Hi I have the a2a Comanche in msfs 2024 and the tds 750 screen is blank and black. When I switch to dual gns only the bottom 430 is working and not the 530 which is also black. Please help me get the tds 750 to show, it just says in gauge mode but not anything on the screen
Have enabled in msfs 2024
And the wasm module shows in community folder
But screen in still blank

Hello,
We are sorry to hear of the issues, we are here to help.
Does the TDS GTNXi Pro function in other aircraft?
With MSFS closed, please start the TDS GTNXi Pro from the desktop shortcut and click on the GTN750Xi button, does the screen light up?
Not to worry, we will find a solution.

Hello,
As the TDS GTNXi Pro works in the default C172, then it seems that the issue is not with the TDS GTNXi Pro itself, as well as the 530 not being powered on.
For the A2A Comanche, please check for electrical/avionics power and make sure to turn on all switches, as well as to reset the aircraft in case of failures.
You can, as well, update(check) for the latest version. In case this does not help, we suggest going to A2A for support.
