Why doesn't the screen light up after the flip of the mobile phone, and the keyboard light lights up at any time?

There are three cases of the mobile phone that has just been dropped, "1", which may be the virtual welding of the cable interface of the mobile phone, and welding is enough, from 10 to 15 yuan!

"2", the cable has been damaged, but the phone you just bought will not be disconnected so easily. If it's a cable, just change it. 15 yuan!

"3", the screen is broken, it is necessary to change the screen. 20 yuan will do!

But what kind of problem still depends on the situation of your mobile phone, just check it, there must be one of these three situations! * Prices are for reference only, because prices vary from place to place!
