help: the screen of touch pro does not work

[semimoon99]

The screen is black, not wet & not dropping.When it is connected to the computer,I can see the mobile works properly by the screen of computer.I think that perhaps the interface line is loose.So I want to take it apart to repair it, but it seems too hard to do. Do anyone have the instruction to do this ? or pictures, or videos, pls hand a direction to me , thanks a lot !
By the way, I'm from China, my English is poor.
