I got up this morning and decided to do an autopsy on the TV to make sure it was the same problem I had read about online. As you can see the behemoth's insides.
If you click on these pictures, you'll get a better picture, but below the back of the tube there are several metal "walls" where the capacitor is located.
Here is the culprit. Again, if you click on the picture, you'll get a much better view, but #2 is the capacitor that has gone bad and is sparking. You can see in this picture that #1 has burn marks on it from the sparking #2 has done. I hope this is easier to fix than it looks like it is going to be.
