The TR signal in power supply adapter is the synchronization with the AC network.  I would like to power scope from a LiPo battery. Is it necessary ?

Probably not, but read here

Hello the R136/R137 and R236/R237 are not 12,2K Ohms. It's 50Ohms (PCB view: https://youtu.be/Mmx7eo9STXE?t=1972) In my DSO2D15 its also 50 Ohms. Its mistake in schematic or in my device?

I have no idea. I have drawn up the schematics 2 years ago by tracing the signals on the PCB and dotting down the values. Never checked if the schematics make any sense. Not going to open it up again to check either.

If your scope is working it is working and I would not bother with it. The schematics are just there for simple reference for someone who wants to reverse engineer it in some way and get some idea about the setup. It is not an original schematic from the manufacturer.
