Circuit sword issue at assembly
Posted: Sat Nov 30, 2019 11:16 am
I'll try and be as thorough as possible. I have been assembling by circuit sword over the passed few weeks. As of today I got a block of time I could hopefully finish it. Got up to step 12 of kites guide. But the screen remained black. The backlight turned on but no images were displayed for the tester mode. Did some digging on the forum for people with similar issues. One guy had solder that had bridged some of the connections on the screen ribbon connector. So I checked there and it didn't really look like I had any bridges. Even took pictures with my phone so I could zoom in super close and exam the pins. Then I checked the same connectors on the pi connector. Doesn't seem to be an issue either.
So then I noticed the 'pgood' LED doesn't light up. So I tried something kite mentioned to another person in his thread. I held down the power button for 5 seconds, with the battery and usb-c cable disconnected, plugged usb-c began in and looked to see if there "PON" light would flash three times. While plugging the cable in, before completely getting it in, the "pgood" light flagged 3 times. But once the cable was fully seated, it stayed off and the "PON" LED never made any flashes.
The fpc cable is oriented correctly and has no damage. The screen itself seems fine as does it's cable.
Any suggestions? Pictures included for reference.
