Hi Guillermo,

This problem is happening to almost all SD1's (at least the 'early ones')

Ketron is replacing the display and makes tiny modifications to the connectors on the board where it is mounted on.
In my case I got a complete board including display..... FOR FREE. Perfect service because my SD1 is > 2.5 years old.

So I recommend : Ask your dealer to contact Ketron for free replacement.
