I have just finished step 12 and I think I did everything right.
The problem is that my screen does not light up every time i flip the switch. Sometimes i find sweet spot wher it works everytime (comepletly normal, it says adjust contrast),but if i move it and try turning the screen on it isnt working.
I tried resoldering batery and checked everything 3 times.
Should i just go on with building or what?
