First the screen "touch" capability stopped working, and then two weeks after that, the back and option buttons stopped working too. And a week after that ,there was like a screen "flickering" (I tried to recreate the problem in the attached image) when I tried to either open or close the slider.
Finally the screen stopped working anymore. I tried to connect the phone to the PC but says that windows cannot recognize the hardware. And there's one more thing: I can turn on the phone, it vibrates, but the keyboard lights seems that are not working, they are permanently off.. and when I try to Increase the volume it doesn't sound either... There is only the black screen and a backlight.
Please Help me to find out what is the problem, I'm thinking to buy a screen replacement on eBay, but some people told me that is the "flex" cable. I'm not sure if there is a fix for my phone's problem.
