either the eggs is screwed up, power it from your power supply; or the smaller ribbon cable is not aligned correctly, it needs to be positioned all the way to the right if the screen is facing up....
OMG. I couldn't figure out what was wrong after I mounted my screen to my dash. I tryed reseating every cable and checking every solder point, I had nothing. Then I finally came online here (I should have done that first) and I read the tip above. I didn't realize that the width of the ribbon cable on the back of the buttons PCB wasn't as wide as the socket it goes into. Well somehow everytime I plugged the ribbon cable back in it was slightly to the left. After reading the tip I aligned it to the right and voila! Everything powered right up like nothing was wrong. I yelled 'YES!' really loud and everyone in my house came to see what was up in my room, lol.
So the point is, even if you re-seat the cables, see if they have any play left and right as well as in and out. That may be the key to your problems.
Thanks Studmonk3y!
