GT2560 v3 Temp Issues

Hello all,

So I was cleaning my nozzle yesterday, my 3 year old decided to climb on me, fell and grabbed the wires on my printer as she fell.
I heard my printer restart. When I checked she'd broken the extruder thermistor wire.
I fixed this but now when I power on my printer it's telling me the bed temp is ~350 and extruder is ~110.
I've took my printer apart and disconnected everything from the board except power and USB and it still tells me the same temp readings.
Is the board fried? Is it something I can fix? I've looked over the board and I can't see anything obvious, no obviously blown components.

Any suggestions?

After doing some searching I found a post on thingiverse where a guy descibed a potential issue if the thermistor wire touches the frame it could send 24v to pin 0 of the chip and this will break the temperature sensor on the chip. I've emailed Geeetech.
