A few days ago I had a very similar situation. Lightning. Tv now just clicks. I have the rear cover off and do not have any bulged or leaking caps. Checking voltage as it clicks on each cap. Don’t know what to do from here. UN46B6000 When I unplug the harness going to the main board I see the backlight turn on and clicking stops. Clicking returns once plugged in. Back of TV:

@usasquint this again sounds like a main board issue. If you disconnect to the cable from the power supply to the main board, check to see if your backlight comes on and stays on. Post some images of all of your boards with your question. That way we cans see what you see. Use this guide Adding images to an existing question for that. I am more leaning toward bad IC’s and/or relays than capacitors.
