Problem with thermistor's on Megatronics 3.0

Yesterday Pronterface ceased to see thermistors on the table and hotende. Resistance to the thermistor 99 and 100. No voltage at Pin thermistors. Engines are working well. Has anyone encountered this problem?

Megatronics 3.0 + Marlin + Arduino 1.0.5

Error in Pronterface:

"Error:Temperature heated bed switched off. MAXTEMP triggered !!
[ERROR] Error:Temperature heated bed switched off. MAXTEMP triggered !!

Errorrinter stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)
[ERROR] Errorrinter stopped due to errors. Fix the error and use M999 to restart. (Temperature is reset. Set it after restarting)"

try running your thermistor wires as far away from AC powered cables as possible? (or for that matter try to keep the away from any unnecessary wires)

They can get some cross talk causing errors like that

I try this. But there is no voltage on the pin of the thermistor. I think this board died. :-((((((
