our Makerbuino is displaying the splash screen correctly but afterwards its just showing
random pixels. Without the SD card, the “insert SD card” screen is displayed properly.
Some background (maybe related):
Apparently when assembling the Makerbuino we did something wrong. The backlight was too dim.
Apart from that, the Makerbuino was working fine.
After about one hour of playing, the display went off. We checked the soldering and adjusted some stuff. Now the backlight is normal but we have the problem described above.
Thanks in advance,
