    I just install the LED Controller on my new machine and back light doen’t work but the contrast is fine. I bought everything but the printed parts from here. Can someone tell me how to fix it or show me where to find out about how to fix my situation… Thanks!

    Its probably the ramps board, the traces for the LCD connector are on the very edge of the board and get easily damaged. This is something I only started testing my Ramps for in the last 2 batches of boards. Sorry for the hassle, I sent you an email last night.
