I saw badly burned boards several times in that model and the 7603.
It's been a few years since I have worked on one, but I don't remember those big caps being a problem. Those plastic discs appear to bulge sometimes, but the caps themselves aren't bulged underneath. You can take that plastic disc off the top of the cap and look without hurting anything.
I know the Philips/Magnavox of that era did have bad caps, but it usually wasn't the big ones. It was usually the 1000uf, 2200uf, 220uf, etc, medium-sized ones.

Unfortunately, those two large ones failed. Very low readings on both, bottom bulging as well as top. They even messed up the plastic rear panel for the tv but you can't see it with out close examination. One of v the c as rattles when you shake it. I'll check the transformer as well. All my other caps look good.
