This topic describes the causes of blank displays that occur during an installation.
During the installation process, you will see some blank displays. Some of these are predictable and the instructions give an approximate amount of time when there appears to be no installation activity. Other blank displays are less predictable because of unique situations on your system. If the processor light is blinking or reference codes are changing, the installation process is active. If the processor light goes out, the attention light turns on, and a reference code appears on the control panel, go to Troubleshooting software installation problems and follow the instructions.
