My Display Is Not Quiet Working

by Osky4 on Sun Apr 16, 2017 11:04 pm

Hi, I have recently been putting together the monochron clock kit and I plugged everything in and changed the display contrast. When I did only random pixels in set straight lines appeared, sometimes on their own and other times in lines - this changed randomly and doesn't seem to fit time. I have added a picture below ( you can see what's happening on the far side from the solder joints). Does anyone know what's happening?

Any help is much appreciated.
Thanks a million
p.s my soldering isn't great.

Picture is fuzzy, but the soldering on the display looks like it's probably OK. Can you post some pictures of the rest of the circuit?

Here are the photos. I have combed the soldering joints and there are none touching.

1. what kind of solder are you using, can you post a pic of the label?
2. does the backlight ever turn on?

I am not sure what solder I am using (it came in a kit, I am mostly sure it is not flux infused) and the backlight does come on.

yeah the solder looks kinda rough, makes me think it could be a cold solder joint. can you pick up some electronics rosin-core solder?
