Basic Checks:
•Run the monitor
•While diagnosing the problem, connect the monitor power cable directly to a known working electrical outlet to ensure that the monitor turns on. Do not connect it to a power protection device, UPS, power strip, or extension cord.
•Ensure that the monitor power cable is firmly connected, verifying that the power cable is adequately connected at the monitor and to the electrical outlet.
•Test the electrical outlet: ensure that the electrical outlet is working by testing it with a different device such as a lamp.
•Test the power cable: swap the power cables between the computer and the monitor to see whether the problem symptoms change.
