Hello.
I also have this issue. The scope is 1,5y old and is very little used. Re-connecting the keyboard cable did nothing.
Please advise how to solve this.

Check this thread on EEVblog, someone had a similar problem and fix it by re-soldering some ICs on the keypad board: https://www.eevblog.com/forum/testgear/hantek-dso5102p-(5202p-firmware)-stuck-on-auto-set/

Problem is U2 on front panel board. Try reflowing decoupling caps on both 74HC4051 mux/demux chips and pins 1 and 2 of U2 (rotary encoder signal pins). My scope DSO5102P now works (mostly).
