Scott,

Try adjusting the contrast potentiometer on the T238+ board. As you go 
through the adjustment range the blocks should become
characters of info. As far as the 7805 5volt  1 amp regulator getting 
HOT. If you are running it on 13.8 vdc it will run hot.
I had the same problem. I decided to run an 8 volt regulator 7808  in 
front of the 7805 to distribute the heat, between the two devices.

Good Luck!
