OK So I replaced the capacitor that I had read elsewhere that was supposedly the problem and it still is acting up, so I tried powering on the TV without the main board hooked up to the TV like you suggested and it wouldn't even power on or even attempt to power on without the mainboard hooked up.

Here's a picture of the TV's mainboard posted below. Is the big black square heatsink in the middle of the mainboard the main chip you were talking about? If so then I don't see how I could reflow the solder on that chip because of it being surface mounted plus the heatsink would probably destroy the chip if I hit it with a blast from the heatgun.
