Hi @toxxic_carress ,
If you have a DMM (digital multimeter) or you know anybody who has one and who knows how to use it, use its’ Ohmmeter function check that the fuse and the surge suppressor on the Power board are OK.
You’ll need to remove the Power board from the TV to test the fuse and the suppressor
Here’s an image showing where the fuse (red box) and the suppressor (red arrow) are located on the Power board.
