Try to check battery voltage or any component overheating, I had something similar problem with a v3 firmware version unit and it was in fact a battery problem. I had the unit replaced.

Panchez:
Change battery, same result, not overheating any elements, processors and ADC heat around 37-38C, other element are cold.  :-[

Try a factory reset through the menu like this: press MENU button then choose SET option, while on SET menu option  long press AUTO button until you hear a bip or read a message on screen. after that turn off the scope and back on. test it.

Did you contact Zeweeii as I suggest previously? See if they send you a firmware for you to flash. Try it also through your seller. If you don't insist they won't care just like most of Chinese sellers.

Panchez:
I washed off the flux on the display cable. Nothing has changed.
I reset it to factory settings several times.

There is progress, I couldn't find anywhere in the instructions how to save the device settings after turning it off. I watched video reviews, I saw it there. I saved the settings from the menu by pressing save. It has been working for 35 minutes without freezing, without sending a signal, while I'm busy I can only observe, closer to the evening I will check everything and write.
Perhaps there was garbage in the eprom.

No one has responded to the letters yet
