I have used my Sony Ericsson x10 mini for 4 months in total. It is now on repairs for 2 times. And the conclusion of repairs has come with the phone that it has been subjected to impact or fall injuries and that the motherboard is damaged. Something I don’t understand some of the phone has not fallen or been beaten because I have hardly used it. And it says that it is not to fix. What is strange is that the phone turns on and Keyboard light, but the screen is totally black. Someone who had a similar experience with the same phone? Please help
