And the video of the sound that seems to come from the wifi chip when the lcd is not connected. https://youtu.be/7Iz90MyGRSo
I will support any informations / photos if needed.
My problem seems to be quite similar to this problem: https://github.com/kiteretro/Circuit-Sword/issues/68 .
I followed the instructions here on github(https://github.com/kiteretro/Circuit-Sword/wiki) to build/test the circuit sword. At the point, where I have burned the image (https://github.com/kiteretro/Circuit-Sword/releases) using win32 disk imager, it wont boot. I also tried multiple sd cards - Same problem.
The PGOOD LED does not light up when the sd card is inserted and I power on the system. All the other did light up in the previous testing steps acording to the manual. The Screen Backlight goes on but it stayes black / shows no picture.
Another thing I noticed: there is a buzzing sound that seems to come from the wifi module when the lcd is not connected.
Ive ssen that you told other people to look at the sd card slot. I havent seen anything that looks likeout of place / not soldered correctly but I dont have that much experience with soldering so Im not sure if thats correct. I hope that these infos help but I will provide images and a video as soon as im back home from work.
