Well I finished recapping the TV and went to power it on and I heard the sound of what sounded like the high voltage coming up but instead of it being only for a few seconds it was for the whole duration of the warmup time and there was no audio, and then I saw smoke.

That's when realized that I installed the wrong value of capacitor in place of C3B which is the filter capacitor for the output transformer, which was supposed to be a 10 MFD 450VDC capacitor, and instead I put a 100 MFD 63 VDC capacitor in its place, which that capacitor is supposed to be filtering the 270V line going into the output transformer.
So because I put the wrong capacitor in, the 100MFD 63VDC capacitor couldn't handle the 270V going into the capacitor which was basically overloading the capacitor and causing it to vent (thankfully I shut it off before it vented.)

And Unfortunately I don't have a 10MFD 450VDC capacitor in my stash like I thought I did (well I do but its an old Sprague "Atoms" capacitor that is really large and it wouldn't fit very easily in the already tight space under the TV chassis), so I'm going to have to order one.
