Hello,

My SD1 is recently experiencing the well-known display problem. I live in Mexico. The ketron dealer is in a far city and it is *VERY DIFFICULT* for me to go there (I had a car accident 3 years ago and I have brain damage, I'm seriously disabled).

Me and my father are electrical engineers, so I think it could be easy to resove this problem. I just need directions about what to do.

Thanks in advance,
Guillermo.
