Even if the ESR has not went bad yet, they can still be leaky as I have learned is often the case when at operating voltages.

Understand I'm coming at this from being an audio guy... common wisdom in audio land is that electrolytics are always suspect after a couple decades, film types are usually good, ceramics can go either way, and PIO types are also usually good. Is there something about higher operating voltages in a TV set that makes PIOs suspect? I'm not saying you shouldn't check them, or even that that is wrong, I'm trying to learn here.
