Hi there, today I built my MAKERbuino, oh boy, what a trip! I loved the experience as this is the first time I did such a thing with soldering and that many components. I only messed with breadboards before this.
Everything works fine except for my screen: don’t have backlight. I already triple checked for bad soldering points but got nothing wrong. I have a multimeter but Im such a noob that I dont know how to use it with this PCB.
Can you guys please give me a hand, with some method for checking the screen ? How do I use the multimeter: black cable goes to ground…but where on the PCB is ground for that?
Another thing is that I have everything soldered so I can’t remove the screen board…can I detach the screen from it’s breakboard without actually breaking it? I tried to move it out but it doesnt go off easly so Im afraid to break something as games and sound works fine.
One note: I accidentally messed the microcontroller socket so I had to solder it directly.
