Hi, I turn on the external power A and I have the PFD1 the rest of screens are in black. I can´t see the voltge on the BAT display, I don't know what's wrong 

copy/paste this from the FAQ. If you go to AerosoftOne > library > A330.... Get Support

 

The procedure below worked for me.

 

 

Blank screens usually indicate that Aerosoft One Utilities is not running on your system. To resolve this issue, follow the steps in one of the sections below.

[Recommended] Reinstall Aerosoft One Utilities and the Aircraft

1. Restart your PC and then launch Aerosoft One.
2. Go to Library > Dependencies > Installed and uninstall the Aerosoft One MSFS Utilities.
3. Go to Library > Microsoft Flight Simulator > Installed Add-ons and uninstall the A330.
4. Go to Library > Microsoft Flight Simulator > Available Add-ons and re-install the A330 (this will also automatically re-install the Aerosoft One MSFS Utilities).
5. The aerosoft-aircraft-a333-pw shortcut/folder and aerosoft-one-msfs-utilities folder should now exist in your <MSFS Packages>\Community folder. Launch MSFS and check if the A330 is now working.

 
Manually start Aerosoft One Utilities

1. Restart your PC and then open the folder <MSFS Packages>\Community\aerosoft-one-msfs-utilities\utilities.
2. Double-click on Aerosoft One MSFS Utilities.exe (the application will start without creating any visible windows).
3. Launch MSFS and check if the A330 is working now.

 
Manually start Aerosoft One Utilities as an Administrator

1. Restart your PC and then open the folder <MSFS Packages>\Community\aerosoft-one-msfs-utilities\utilities.
2. Right-click on Aerosoft One MSFS Utilities.exe and then click Run as administrator (the application will start without creating any visible windows).
3. Launch MSFS and check if the A330 is working now.
