When a TV, or monitor really, is over ten years old, even functional caps do not have the *ahem* capacity they did when new. Without the AC modulation they provide for, at the tolerances required across the circuit, you can get all kinds of undesirable results. And when I consider any television I come across today, or in the past few years that I've been looking out more for that matter, are at least or almost that old, absolutely, a cap replacement is in order. Some of the nicest, newest CRTs of various brands are victim to some of the crappiest, cheapest capacitors, all kinds of electronic products made from around 2003 to 2008 suffered this, and those most desirable CRTs happen to have a good cross section in that timeframe. If you have a service manual it's simpler with a parts list, but even an amateur can look up the rating, digikey and others have low prices, less for certain volumes which you just might come across multiples in a single board. That, an iron, and a multimeter, and you're ready to do something about your problem and learn in the process.
If someone doesn't know what electricity is, or what ground is, and how they are important together, if they've never attempted to bridge a wire, have an iq of less than 100, or what have you then I suppose, sure, it is not "simple" to get going with this stuff. But honestly, I don't see a normal human being setting the house on fire, killing the cat, or even destroying the board. It really is not as difficult as you make it out to be. With google on your side, youtube tuts galore, and even testimonials in this forum, the last thing I'm going to tell anyone is not to even try.
