Q: i have some error with my iphone 5 in black screen nothing shown

is this the original iPhone 5, or 5s? If it's the 5s do you have Apple Care still? If so calling Apple iPhone support is where to start, hopefully they can help, if not, setting up an appointment at the Genius Bar at an apple retail store is a good option too, Call the store first though and ask what your options are in terms of warranty and service. If you are having problems with the regular iPhone 5, still call Apple Care or an Apple store and see what they can do.

good luck!

K?
