So, not being able to determine where the short was I decided to try again with new components. During the test I noticed the display scramble when the keezer compressor kicked on. I grabbed a 2.2uf 160 V cap I had and soldered it onto the uno's power jack. That seems to have taken care of the scrambling when the keezer kicks on. Now if it will stay stable I can put it in the box.
Well that didn't take long. Same issue. I'm starting to think my cheapo uno can't handle the load of powering the lcd.
