Why Won’t My Dell Monitor Turn On At All?
If your Dell monitor refuses to turn on, the first thing to check is the power cord. Ensure it’s securely plugged into both the monitor and the power source. Also, verify that the power source is functioning properly. If you’re using a surge protector, try plugging the monitor directly into the wall outlet. If the issue persists, it’s possible that the power button or internal components might be faulty.
