Its fixed, sorta.
I reinstalled the batteries and hit the ctc button, and again all the pixels lit up and I couldn't read a thing. I then just continued to hold down the CTC button. Both the screen and the buttons flashed on and off several times and then bam, the screen was back to normal.
I think I will still call Lionel and have it sent it for a warranty repair. The battery charger stopped working several months ago.
