Magnavox FP5230 repair

I just got this Magnavox FP5230 television off of Freecycle. I figured it'd be nice for awhile, and get me more involved in home electronics. I did some stuff with electronics in college, but apparantly not enough to scare me away from it. I wanted to share my thoughts on what I'm getting into, and I hoped you guys could make sure my head's on right to do this; you might even answer some of my questions.The original owners had the television inspected, and they were told "the board" is fried, due to the voltage regulator attached to it. They were told this is somewhat common for that model. The parts should still be readily available, and I'd be looking at $400 if I had a tech do the parts and pay for labor. I was hoping to muck with it myself though. Is there a diagnostics procedure specific to those components I could take to second what was told? I don't know the techs these people chose, so I want to try and independently verify.What I have done so far is hooked up an external input. I managed to get audio out of it, but no video at all. Nothing comes up when I push the "menu" button. So it looks like I'm not getting anything on the screen at all.I'm assuming "the board" is the "video processor board" that I see coming up on google. Where do I look for the part number for that and the voltage regulator?Regarding the voltage regulator, is there anything further upstream I should be checking? I don't know where they kept the television, but I'd assume the thing just got too hot after years of use. That sounds common enough of a problem, but I wonder if instead there'd be a component that could trigger that regulator, and that I should be replacing it too/instead.

Ah yes, the infamous Chevy 268 Cubic Inch V-8 for the Monza. Definitely a design nightmare from the mid-70's! Most owners just left that last spark plug in there and did not change it till it caused a misfire condition...

I had a '70 Impala with a bad heater core. I futzed and futzed trying to figure out how to get that *last* bolt out. I finally gave up and consulted the official manual at a friendly dealer.

Official method: *DRILL* the bolt out from the inside...or else remove the inner and outer right fenders.

Guess which method I chose....
