Just wait, i've posted him your problem. He should answer within 24 hours, maybe faster. Image you can attach as an attachement or upload to any ftp server and post link to the image in img tags.
Well i've got the answer. At the moment he can't help you, but maybe in future it will be possible to resurrect your main board. Just search for Xperia SP with broken LCD and swap main board - that is the cheapest and fastest way to fix your phone at the moment.
