Have you tried rebinding the Transmitter to the receiver ?
If you have the manual or check online for a manual to see what you did and may help get it working
Sorry as i have no experience with Flysky kit

No, I haven't tried again to "bind" it. My main concern is that no programs are displayed on the screen anymore. I'm going to consider buying a simpler 6-channel radio, even though it bothers me a little, or even a lot, to have a superb radio and not be able to use it.
Thank you anyway for taking the time to reply.

Your welcome mate

I tried a Google search using this format in the search box: blank screen "Flysky".

There seems to be a lot of discussion of the problem of a blank screen on various Flysky transmitters (i.e. 6 and 9 function). Here are just a two such discussions. If you run the same search, you can find quite a few more ideas:

Hi,
It seems that you have turned the LCD brightness/contrast all the way down.
To undo it, you have to blindly type it out.
For the menues see atached manual.

Hello and thank you both so much... I'll try all of this quickly and keep you posted, that's great, have a good day.

Okay, so after reading and rereading, then transcribing it onto paper to make sure I didn't forget anything, pressing the "Menu" button changes nothing (except for a brief beep?). The screen remains stubbornly green, with no display. The battery has been recharged, so that's fine. I confess I don't understand it at all. I still remember the moment I did that stupid thing: "simultaneously pressing one of the right-hand buttons, Menu or Exit, and one of the left-hand buttons, Up/Down or Plus/Minus." It will remain a mystery to my little brain.

I recommend a new transmitter.
Spend a little more money on a transmitter with a multi-protocol module, such as the Radiomaster TX16.
Then you won't need to buy new receivers.

Thank you for your reply, thank you again
