Works like a charm and requires very little work and effort.

I may try to somehow get the power button to stay depressed, thanks for the suggestions guys.

Soldered pin 2 and 25 to the power contacts on the remote and put it fairly close to the remote sensor on the tv. When the pc boots it polls the lpt port which in turn powers on the tv. I have the lpt port disabled within windows because it will poll when windows starts. I run a shutdown script to enable and disable the lpt port which powers off the tv. It wasn't really that hard and is pretty reliable.

That sounds convoluted. Why not just go from the LPT port to a relay for the TV's power switch? (Or an optoisolator.) No need to involve an IR remote in the process.

I was nervous working inside the tv and wasn't really interested in soldering to the board. I'm sure there are a ton of different options to get the same results. I picked the approach I was most comfortable with.
