Sounds like that ADC on the mega is damaged...
Try moving the bed to T2 (change the pins numbers in pins_ramps.h and move the plug)
ramps schematics [reprap.org]
lcd schematics are the same as these [www.sintron.co.uk]
#define TEMP_0_PIN 13 // Analog Input 13 #define TEMP_1_PIN 15 // Analog Input 15 #define TEMP_BED_PIN 14 // Analog Input 14

As for the "blinking" menu and the not working KILL and RESET:
Are you sure that your EXP2 cable is not somehow rotated 180 degrees on one or the other side?
Are the two 10-pin cables identical with regards to the position of the connector locks?
There are different versions of cables, controllers and adapters, as to the position of the connector locks, so that a wrong 180 deg rotation of the EXP2 cable could cause the kill, reset and encoder pins to be wrongly connected (and also the SD card would not function, as its signals are also on that connector).
Below is a schematic of the RRD smart controller, so you might want to check the connection of the EXP2 cable:
