First, it is normal for the Nokia phone display to go blank during an update.
However, it may be that the PC update application Nokia Suite has lost contact with your Nokia phone and the phone display is suspended.
Do the following:
If there is still no response, take your Nokia device to your nearest Nokia Care point. If the device is within its warranty period, Nokia will repair the device under the usual warranty terms and conditions.
Note: If the Nokia device is not within its warranty period, Nokia is not liable for any loss as defined within the End-User Software Agreement.
Try the following troubleshooting tips:
Charging times differ between charging models. USB charging is limited by the maximum current output of the USB device, and may take longer than charging with conventional chargers.
Note: all batteries including high-quality batteries like Nokia's will eventually lose power retention capacity. If it is time to replace your battery with a new one, be sure to purchase an original Nokia battery from an authorized Nokia dealer.
You need to have the Nokia Suite application installed on your PC.
To download and install Nokia Suite, visit your local Nokia website www.nokia.com/nokiasuite.
Once you have Nokia Suite installed on your computer, please do the following:

From 2013, the new Nokia Asha/S40 phones do not support Nokia Suite or PC suite. Instead, they use the Nokia Connectivity Cable Driver.
Here are the steps to take in this scenario:
The blinking closed envelope icon indicates the SIM card message memory is full.
Select Menu > Messaging > Options > (View folders > Options) > SIM messages and delete one or more SMS messages.
Note 1: Class 2 messages (for example, service messages from operators) are stored in the SIM card message memory. Once the SIM card message memory is full, Class 2 messages can't be received.
Note 2: You have used a Nokia S40 product before. In S40 products the SIM card message memory is filled before the device message memory. If you insert a SIM card with full message memory to another device, a blinking message icon appears on the display of your Nokia device.
Note 3: Other reason could be that there is not enough free memory available on the device to store the new message. To release a space go to Messaging > Inbox and remove unnecessary messages
If you are unable to test your phone or it still keeps switching off, please bring it to the nearest Nokia Care point for inspection.
These simple steps can help in a majority of cases.
