The only concern I have is the 3-pin screw terminals being used with the breadboard - their pins are quite a thick gauge and you might find that pushing them into a breadboard can damage the breadboard or create an intermittent connection fault.
I was using a pre-pixel version at the time of that tutorial, but that shouldn’t affect anything. Perhaps the last effort would be to try a fresh image of raspbian? If that doesn’t work, shoot us an email and we can go from there.
Hi Sam. was the first thing i did. Thought i might have broke something. There is a lot of chatter regarding this issue. I have added lines to the config.txt file as some of the raspberry forum’s suggest.
