I have completed the assembly instructions and have done some initial debugging. But so far no luck:
- Some LED lights are on when connected to power
- once the screen flashed for a second
- reset button tested
- removed also the memory card
Did again a visual inspection of all the soldering points, they look ok for my inexperienced eyes.
Now I am wondering what todo next. I have a Multimeter but not no idea how to use it.
Any tips would be much appreciated!
