Hey Trash!
I've got some bad news for you. I was reading about interference generated at 14.318MHz - and noticed that it's very common around NTSC equipment. Why, you ask, is this important?
14318180Hz is exactly four times 3579545Hz - the NTSC Chrominance encoding reference. (two signals that are 90° out of phase, but I digress...)
The good news? You don't have to desolder that can.
The bad news? You need to look elsewhere for how the card generates the vertical synchronisation signal - that can is just a colour timing reference thingy. You might find some manner of phase-locked-loop circuitry on the card to interpolate a higher frequency from the 14.318MHz - that could be a starting point.
Let us know how you go, if I can think of anything regarding this I'll be sure to pipe up.
