Space PI Touch issue

Hello!
Faced with the problem of using a dryer. At first, I began to notice that if the device is hot, then the two left buttons of the sensor do not work. But when the dryer cooled down, everything worked fine.
But today the cold dryer refused to work at all. The two left buttons (up and gear) do not respond. Press down and turn on/off - they work.

Now I can’t turn on the dryer because of this problem.
I checked the touchscreen signal with an oscilloscope - when the buttons are touched, the signal at the screen output closes to ground (that is, the screen is working). Then everything is connected to the main board, probably the problem is somewhere there.

Has anyone encountered such problems? Perhaps there are ways to control the dryer without using a touch?

Thank you
