HELP!!!! SCREEN PROBLEM

Post by coolcrawler » Tue Sep 04, 2018 6:23 pm

Well I finally got my screen in, soldered it to the board with as much precision as possible. I tripled checked my connections, and made sure there was no shorts. I fired it up (not literally fired it up, that would be bad) and it booted up to the "Loading" screen. after a few minutes the screen went white. I was like "Okay, Wermy said that it would take forever to boot"; so I waited, and waited. After 15 minutes, I decided that something was wrond. But Upon inspection I couldn't tell what. My screen was fine, I have a good raspberry pi, so whats up? Please, please help me.

Check all continuity on the LCD board test pads to the actual GPIO on the pi. If you're using a battery be sure it's fully charged, I've had power issues when the battery is not fully charged.

Don't contact me about obtaining my board files (as you will not get them). If my Boards or PCB Kits are sold out, they will be restocked as soon as I can get them and there is demand for them. You can join the mailing list on my Website to be notified when they are available.

Yep. Im using a power supply and made sure all of the connections are connected between the screen board and the GPIO Pins.

In attempt to making my screen work, I ended up runing my screen board. I am not exactly sure if I "ruined" it, but I messed it up pretty good. I for dure lifted a pad and bridged a few connections. I tried using solder wick, but that still didn't help. If anyone thinks that this might be salvageable, lease contact me with suggestions.

You can just push the solder from the pin of the LCD ribbon to those exposed traces or use a tiny wire and why are you making new threads about the same subject? keep it in one place.
