Hi,
I tried something similar to what you describe, but my display still refused to work. In the end I got some spare parts and started replacing parts. I then quickly found out the RAMPS was faulty. It looks like your problem might be different than mine, but if you have the possibility, it could be worthy it to try another RAMPS.
