Problem loading firmware

StuartAndrewsStuartAndrews
in Repetier-Firmware
I am trying to load Repetier firmware on two Arduino mega ramps 1.4 main boards with Reprap Smart Controllers.
I have tried loading 1.0.4 and 0.92.9 firmware.
Both appear to successfully load and I get a steady green LED on the main board.
However, all I get is an empty backlit screen.
One printer is fully built and has a power supply and I tried loading the firmware with no success.
As a double check I have just tried the second Arduino off the machine and got the same result.
I have successfully built another machine and these two are clones of the first.
I had no major problems loading the firmware in the very first machine.
Any hints at what I am doing wrong now.

    I have cured it....  I reduced the contrast on the pot, and low and behold the screen displays the text now!!!!

    well one of the boards seems to work okay... the other now has text on the display....  However, it appears to be constantly cycling through the start-up and the green LED is flashing at the same rate.
    Have I damaged the board in some way????

    Do you have something like Repetier-Server installed that might try to reconnect constantly and fails, but still causes the reset?
