I have a LG 55LM8600 that stopped powering up after a storm. From previous experience and reference another post (link below) for the same issue, I replaced the power supply board and main board, but still no luck, same symptoms. I have not checked voltages etc. as I was ok with throwing boards at it based on the information at hand. Any other suggestions on what this could be?
