No Hotend or Bed

All I can say is, this is a really great little printer. very reliable.
Up until now, it was doing great.
My bed was not warming up, I noticed that one of the thermistor wires was no longer connected to the bed so I resoldered it, but now both my bed and extruder do not work. I may have short circuited the board. Not sure yet. The temp display in Repetier says my bed is at 272 degrees celceus . even when I disconnect the bed and thermistor from circuit board. and reboot. I’ve tried resetting the board but no help.
Another note, I can home my extruder but then no other commands work…up Z Left X etc… Bed and Hotend cold. Any thoughts out there ?
Thanks
