Cockpit SX 9 LCD screen switches from main to telemetry menu

[ammo]

After switching on the TX, the display turns automatically, without touching the LCD screen, from the main menu to the telemetry menu.
This happens even without any RX connected.
The TX is working properly, I can use it normal to fly and the touch screen is working normal by touching it but switches after 20 seconds every time to telemetry!

Do you get some telemetry warnings? Could you send a video?

Dear Mr Andreas,

I had NO telemetry warnings.
This morning, the problem did not occour anymore (?).
The touch screen works properly again.
When this error repeats, I"ll inform you.

Best Regards,

Please check the corners between the plastic of the transmitter and the lcd, if there are some particles between, they could cause the behavior....

Thank you for this information.
On the first look, the screen is nice and proper, I"ll check the corners of the LCD for foreign particles.
Best regards
