Regarding caps - the do go bad and did go bad even when I used to work on these when they were only a few years old.
My first step when suspecting a crappy *electrolytic* was to get out a heat gun (careful) or a hair dryer (safer) and warm up the board. If the picture stabilized or even corrected itself, I'd drag out the ESR meter and have at it once the board cooled off. With the schematic, you can limit yourself to the areas around the jungle having to do with video and sync.
