Explanation

When the power LED is on but the screen is blank, the issue could be the monitor itself or the video signal from the computer. The best next step in troubleshooting is to test with a known-good monitor (A). This quickly isolates whether the problem is the monitor or the PC's video output. Checking warranty (B) is not a troubleshooting step. Replacing the power cord (C) is irrelevant since the power LED is already on, confirming power delivery works. Swapping the video card (D) is too invasive before simpler tests are done - always follow the principle of least invasive steps first.
