Jumper T8SG V2 Plus strange problem

I have had very strange occurrence which so far I have not been able to resolve.

It just happened, the following are the symptoms that I have noticed so far.

On Main Page

Trim RV:- Works correctly when pulling down

Trim RV:- on short up activates a timer. Left enter arrow stops timer

Right enter arrow starts time. Timer has been set off Throttle stick as countdown

No timers reset switches have been allocated

Trim RV:- on long up activates GPS

Trim RH:- On short to the left is normal

Trim RH:- On long to left activates both LH Aileron Trim and Up throttle trim together

Trim RH :- to the right cycles thru the Main Menu

Trim LV:- will travel both up and down on short press and long press

Trim LH:- seems normal

To try to fix this I have flashed the Nightly Build that I have been using, and transferred all the models back and the problem remains

I hope someone has an idea about this one it does seem strange.

Cheers

I realize that my post is very long winded and probably difficult to understand.
It is hard to describe the symptoms with words

It would probably be easier to analyze with a video.

Attached is a video which hopefully shows my problem.

To me it appears to be a Transmitter Hardware failure.

Yes, it seems consistent with a problem with one or more of the button matrix connections. Check the processor pins for shorts or poor solder joints.
