@jumpman_5656 teh very first thing you want to do is to rule out everything else. Disconnect everything from the back of your TV. Cable/Sat box/ Firestick/ Game console/DVD? BR everything has to come off. The unplug the TV. Hold the power button down for about a minute. Plug one input source back into the TV. preferably a local source like game console or DVD player. Then plug the TV in. Now try to power it on. Works? great situation resolved. Does not work? Bad. Time to remove the cover and have a look at the board. since you have no sign of live the number one suspect is always the power board. That is the board where the power connects to. Of course you do want to unplug your TV when you remove the back. Do not touch anything on those boards yet. Take a couple of good pictures of how the boards are situated on your TV and pictures of each individual board. That might help us to closer identify what is going on with it. 在已经存在的问题里加入图片
Check your outlet and the power cable before you take it apart. Just making sure your outlet works.

Unplug it, and leave it unplugged for at least 5 minutes. Then plug it back in.
