Try updating the firmware via MIDI-OX or Dmitri's update tool.

And all connections between Amtega and LCD are correct.
I checked the voltage values on my LCD. LCD is highlighted. The voltage between pin 15 and 16 is 4V, voltage between pin 1 and 2 is 0V

And connections are ok.
I second that. If there is 0V between pins 1 and 2 then there is a problem either in the connecting cables or on the board.dmitri wrote:If there is no 5V there connections are definitely not ok.
