yesterday I received my second Makerbuino (I took the first one during last MakerFaire in Rome) and started asap to assemble it.
I arrived successfully to step 12: turning on Makerbuino, the screen showed my a message telling me to adjust the contrast, like the one published at step 23 (https://makerbuino.com/wp-content/uploads/2017/08/DSC05743_800x533.png). Of course, I couldn’t d oanything since still I hadn’t soldered the push button and all the other components of chapter #4.
Then, I continued with steps in chapter #4 but, at the end (step 23) only backlights work on the screen: no message, no text, no sound.
I tried with hard reset (turning off device, inserting sd card, pushing C button, turning device on again, releasing C button and waiting for more than 30 seconds). I also tried hard reset twice times in sequence.
The LiPo battery is charged.
It’s quite frustrating.
I’m not an expert in soldering but it doesn’t look as a too bad work.
Here is some shots of my work.
Can someone give me some help or suggestion?
Thanks a lot.
