Plugged it in with the back off, the smoke is coming from burning on the board about 6 inches above the power supply.

@knarf1 well sounds like one or a couple of components went up in smoke. Unplug the set and do not use it until you identified the issue. Let us know exactly what model your TV is. Remove the back of your set and take a close look at the boards to see if you can identify which component(s) have gone up in smoke. Post some good images with your question so we can see what you see. Use this guide for that.

Looks like multiple failure here.

Burned capacitor and possibly bad IC. You can either replace the complete power board or try to find a schematic to replace the individual parts. We still do not know what model your TV is. Repalcement power supply is available at places like this and many more.
