Not powering on due to lightning ⚡

Hi,

Your LG TV has been struck by lightning and damaged it. Buy a new TV

@felixsoffi you are not telling us what your TV actually does do. If the power LED lights up when you plug your TV on or hit the power button, the chances are high that this failure originates with the main board. If the power LED does not give you any sign of life, it is most likely the power board that needs to be replaced.

The best thing to do would be to remove the back cover from your LG 32LJ500U-ZB Tv and to check those boards for any damaged components. Take some well-focused pictures of those boards and post them with your Question. That way we can see what you see. Adding images to an existing question - iFixit Repair Guide

You can find the service manual for your TV on this page LG 32LJ500U-ZB Help: Learn How to Fix It Yourself. under the Documents Tab. The flowchart on page 24 shows you what to check for a no power situation.

Let us know what you find out.
