The 7-8yr old Samsung SmartTV is shows "Samsung SmartTV" logo when powering on and then reboots again. I showed to a technician and he said main board is corrupted. I read online and seems that main board is corrupted. But the other technician said software issue. I am not sure what to do. As new board is not available and not sure if its repairable. I came to know about universal board. This one - https://www.faritha.com/products/lcd-led-tv-board-45-inch-tp-v56-pb801-combo-board-with-remote Not sure if this will work or not. Any help would be appreciated. Thank you.
