Flickering white screen; at wit's end

Too funny. Alright, another thing I noticed was a lack of solder on the screen points (https://imgur.com/zxihvJZ).

Most of the connections look like they are not soldered properly (too little solder). My concern with these is that the connection is insufficient. The SDO/MISO GPIO connection has a good amount of exposed wire that it is also at high risk of shorting by being bent and making contact with the wire or pad for LED. Although I'd recommend eliminating as much exposed wire as possible, most of them look like they could benefit by just having a bit of solder to fill the gaps. Heat the pad and apply the solder to the other side of the pad and it should flow right into the hole.

I had the same thing with my screen. I think it might be out-of-batteries
