I have the same issue with the heated bed controller... just put in line with an ammeter and is pulling 5.66A which is right for 11.8 volts to the FET and 2.0 ohms for the bed but its liquifying the solder on the base of the board.... too hot i think!!
My LCD worked fine as long as i had megatronics V2.0 selected on the configuration.h think its option 701.
