What should you do first if the LCD panel of a Dell™ Inspiron™ is suspected to be faulty?

In troubleshooting a suspected faulty LCD panel on a Dell Inspiron, running the Enhanced Pre-boot System Assessment (ePSA) is a logical first step. The ePSA is a built-in diagnostic tool that can help identify hardware issues before making any physical changes or replacements. By running this diagnostic test, you can quickly determine whether the problem lies with the LCD or if there are other underlying issues, such as problems with the graphics card or system memory.

This approach is beneficial because it allows for a non-invasive assessment of the components, helping to avoid unnecessary replacements and ensuring that your diagnosis is based on reliable data. If the ePSA indicates a fault with the LCD or related components, you can then proceed with further troubleshooting or replacing the affected hardware. This methodical approach reduces the risk of misdiagnosing the issue and ensures that you take steps based on accurate information about the system's condition.
