If you don't have experience working with electronics, it would probably be better to just pass on "free" TVs. A video isn't going to cut it. IMO, you need some classes and experience using repair and test equipment and a lot of instruction on safety inside of a device. It could take some deep diving and expensive test gear to figure out what's amiss. The last thing you want to do is swap out a lot of parts and either have it still not work or - even worse - have it power up only to exhibit some other problem, such as intense burn-in, busted ports or what have you.
Half of the flat panels I own were bought for next-to-nothing and needed little more than a firmware update or a power connector replacement. I've replaced the power board on one Vizio that was dying, but I could tell exactly what was wrong by the set's behavior. That's from experience. Prices on new TVs have fallen to the point it's just as easy to replace one rather than spend the money and time to fix an old one. Granted, that doesn't apply to plasmas, but unless you know the condition of the set before it quit and have someone who has experience troubleshooting electronics, I'd leave 'em be.
Walking the fine line between jaw-dropping and a plain ol' yawn.
