My mobile phone Sony LT29I suddenly turned off when chatting, and the screen didn't display, but when I pressed the virtual key, there was a vibration response, that is, the screen didn't display.

Since the machine was brushed, it didn't solve the problem. I think there is something wrong with the display. If you want to disassemble the machine, you should wipe the cable again. Generally speaking, it is useless because the display screen is broken, but the touch screen is still useful, isn't it? If it doesn't work, it is estimated that the cable may be bigger.

In this situation, there is only a great possibility of silence.
