Thomas T Henrico , NC July 29, 2023 The grounding pin was pulled out of the plug for the power cord I replaced the power cord. Four screws to remove the panel in the back, one screw for the grounding wire, and reattached the connector on the power cord. Reattached the panel and the four screws. So easy, a caveman could do it. Do-It-Yourself Rating: Repair Time Estimate: Less than 15 minutes
