I’m building the jay D and I have soldered everything, I’m tryed to power it on but it is not powering on. I used a wall adapter that uses 2A and 5V dc. I checked the soldering joints and they seem alright. After plugging in the power I checked with the multimeter the 3.3v and the ground terminal on the screen and they seem to be providing 3.2v which is good, what else can I test to narrow down the issue. I am a beginner so any help would be useful.
