@samdamji it will be difficult to find a proper panel and it will most likely cost you more than a new TV would. Remove the back from your TV and take a look at the label on the panel. Use the model number on that to search for a replacement. The only other way would be to find a TV with the same panel as yours but that is otherwise broken. Then harvest the panel from that one. To replace the actual panel is not as bad as trying to find a replacement
