Touched up all display board connections and now I get two lines on the right side of the display.
Jim, so something was wrong in this area. Maybe you fixed not all. A missing connection is bad and also some unwanted connection between pins. Such an unwanted connection between neighbour pins may produce what you see.
Please check resistance between neighbour pins starting from LCD pin 3 up to pin 15 (2 - 4, 4 - 5, ..., 14 - 15). The value should be very high. Check the display board alone and connected to the mainboard.
Not only a short but also a higher resistance could bring problems. (And if you will find a problem I guess it's around pin 7 ... pin 14).
