Hantek DSO5072P

[Bernardo Lucas]

Hello

I have a Hantek DSO5072P oscilloscope. Initially I had a problem with the backlight that I was able to repair. At this juncture where the backlight was faulty the whole oscilloscope functioned normally. But now he has another problem after being accidentally turned off while starting. It was all uncalled and unconfigured, when I try to calibrate it always goes wrong. Can someone help me with my problem?
I think that if I did a full reset and loaded firmware again the problem was solved, but I do not know how I can do it or if it is possible.
