I had a similar problem with my Loox 720 screen and needed to be replaced. I was suggested PocketPC Tech. Total, it took one week to send the unit from Australia to the US, repaired and sent back. I strongly recommenc PocketPC techs. They will charge you $US229 for repair plus postage. Their web address is

Good luck with the repair.
