I was updating my system the next thing i saw was blank white screen but now i doesnt come up again even the white screen. What can cause such problem?
MacBook Pro, iOS 9.0.1
Hello i have tried all that you said still nothing happen the problem is that the screen is blank even if something popup i may not be able to see it because is blank no light nothing showing in the screen
When you power up the MBP and hear a chime, then it may be beneficial to attache a monitor to the MBP and try what has been suggested. If not, then the best option is an appointment at an Apple store genius bar or a repair facility. I sense there are hardware problems with your MBP.

Guide me on how to connect monitor to the system
It depends upon what connections there may be available, both on the MBP and the monitor:
