[Solved] GearBest Screen Doesn't Power On
Posted: Sun Nov 05, 2017 1:23 am
I was trying to test my GearBest screen before starting on my build and I can't seem to get any output whatsoever.
I haven't done the 5V mod yet. I have a 12V Molex power supply and wanted to test with that first.
I connected the video to PP24 on my Pi 3 and the 12V and ground coming from the power supply. I think I have the display connected properly (snug fit in connector), and when I test the 3.3V and ground through holes on the controller board I get a proper reading, meaning the controller board's getting power. I also tested PP24's voltage and I got the same reading on the connector of the controller board
About the only thing I didn't test thoroughly was my Pi's composite out as I don't have any displays that would take composite video.
I'm also using input 1 on the display (white wire), but I assumed any wire would work with the screen switching if it needed to?
Thanks. Here's a picture of my controller board and display. Nothing's been modified yet.
