I tried all three drivers inside LE and no power on dvb-t2 coaxial input.
Did you measure that there is 0V DC on the coax, or are you just guessing? If the latter, what do you base this on?
This is important because if the voltage is present, but there is a bad signal or ablolutely no signal at all, then the whole thing leads to a dead end, and we are trying to trace a non-existent error. If you don't mind, I'd like to avoid that for obvious reasons...

With CE each driver has power on dvb-t2 coaxial input, also when I restore CE backup on LE dvb-t2 coaxial input had power.
I cannot understand your whole procedure in this way...
When you restore the CE backup on LE, do you restore it together with TvHeadend? I mean with the complete add-on and its settings?
^ This is quite important information, because now I don't even know whether you are using the CE's or LE's TvHeadend binary.
According to the signs, the problem is not caused by the driver, because it is integrated in the image. However the TvHeadend binary is not!
By the way, you didn't write which TvHeadend you use, v4.2 or v4.3? And are you absolutely sure that you managed to set exactly the same settings in TvHeadend during the clean installation as during CE? (Especially whether the settings of the multiplexes match.)
I need specific information, because this way I'm just groping in the dark. I don't mind if you write a short novel, I just ask that it have tangible information content, some logs, screenshots, whatever...
