You will lose saved numbers and message. https://www.google.com/search?q=vista+390+phone+factory+reset ..

A 9116 N has a power brick that needs tone plugged in to it. They are usually a black power brick. Without the brick there is no display If you are referring to no caller I'd. That is a function that you have to ask for from your provider. A blank screen usuall has a funny weak ring also. If you have a grey power supply look at the voltage on the brick if it say that there is ACvoltage output. It is not the correct one. You need to have a DC voltage output on that type of phone
