Hello!
If anyone has knownlegde about the DSO138, help would be much appreciated!
My problem is that it wont turn on. It's presoldered, so it's right out of the box. When i apply my 9V DC power supply it's just black screen, nothing happends. The thing is that this is the second one i receive from the company i ordered from. The first one also did not turn on. I tried 3 different supplies, all 9V but one with 150mA one with 200mA and one with 400mA. The supplier doesn't know anything about it and cant help. Am i doing something wrong? because as far as i can tell from tutorials and things i read, it's suppose to turn on when applied with a power supply.
Thanks!
