Others might post a different method, but in the event that someone doesn't have a step-by-step instruction, there is always a service manual available on samsungparts.com.
Hope that helps.
I need instructions on how to remove and install the left side inverter board in my Samsung 46" TV. I have determined that it is a bad board because I only get audio. Believe me I have checked everything. Also, if I put a hair dryer blowing warm air onto the board the TV produces a picture when turned on after only a few minutes of warming up the board.
