BB Torch :: Screen Goes Weird When Keyboard Is Out?

I am new to this forum and I have got a huge problem. A week ago, my bb Torch started to act weird when I needed The keyboard. The screen went black, or The screen got mirrored. but everything still worked when The keyboard was not sliced open. Yesterday, my bb just went black when i opened The keyboard and this time, the screen stayed black. I think there is something wrong with the software on the chip that controles the visual for the screen. Because even when i had mirrored view, it still responded on the touchscreen, but the things you saw just didnt match with What you touched. What can I do? I bought my bb online, so i cant go back to the store.
