Hi @vagabond_savant ,
Disconnect the power cord from the TV or the TV power cord from the wall outlet depending on your situation.
Press and hold the TV Power button for 30 seconds to dissipate any residual power left in the TV.
Ensure TV is not situated where you have to walk across carpet or similar floor covering to work on it. This will generate static electricity in your body, which could damage some components in the TV if you accidentally touch them during the course of the repair.
If you have a static free path to the TV repair area, grab hold of the kitchen tap or spout to discharge any static electricity in your body. Half joking when I say this but some people generate more static than others.
You might think that I'm more interested in the TV than you, but the TV is in more danger of damage from you than you are from it at this point
When removing / replacing pcb handle by the edges of the boards and not place palms / fingers across components.
Above all stay focused on what you are doing, keep a screw count or put them safely aside in a container, if you drop one into the TV find it as you don't want loose metal floating around in the back of the TV.
Study the type of cable connectors that you have to disconnect so that you don't pull the cables out the wrong way and damage the connector on the board.
You'll be fine.
Good luck with the repair
