Help with possible short - won't display SD card files
I accidentally touched a wire (one of the thermistor wires, I believe) with the metal tip of a tool a couple weeks ago when I was removing an extruder blob. There was a spark. Printer now powers on and off normally and the display still works, however when I insert an SD card it looks like it is trying to read it and then it shows the startup screen and then goes back to the basic LCD info screen. No error message about the card, and it does this no matter what SD card I put in. I am sure I shorted something but I don't know what, so I am unsure how to repair. Any guidance?
