c.ship the monitor back to the manufacturer with a written description of the problem\

my answer is a

Right

Your answer is correct. The next step you should take is to check that all the cables between components are securely attached. Here is how you should go about doing it:

1. First, make sure your computer is turned off.
2. Trace all the cables connecting your monitor to the computer. Check that each cable is firmly connected at both ends - where it connects to the monitor and where it connects to the computer.
3. If any of the cables are loose, disconnect them and reconnect them securely.
4. In addition to the video cable, also check the power cord of the monitor and ensure that it is firmly plugged into a working power outlet.
5. Once you have checked all the cables and ensured that they are securely attached, power on your computer and check if the display appears on the monitor.

If after this process the display still does not appear, you may need to troubleshoot further or seek assistance from a professional technician. The other options listed (b, c) are not necessary at this stage as they involve potential hardware issues within the monitor itself, which you should only consider if the cable connections are secure.
