It's often easier just to go to the circuit board level with modern stuff, find a used board or a donor TV for parts. But used TV's are often so cheap it's not worth bothering, it's cheaper to get another than the repair cost, and if it's a new one then it's probably still under warranty.

I thought it was interesting how he explained what looked like an obvious repair of failed led strips wasn't the actual problem

He is undoubtedly an ace repairer for certain. But for anyone looking to get into that kind of repair then finding non - smd stuff to work on is going to be a lot more rewarding! The tracks can be multilayered under the varnish, have double sided boards so they are virtually impossible to trace, then you can wind up determining the fault is at some programmable IC with custom sotware and it can be very fiddly replacing components unless you have the specialist equipment to fit that particular IC package. Also things frequently fail as part of a chain reaction, say that capacitor was overloaded because of an intermittent regulator that only fails when hot - after prolonged use it could go again! Not saying it will, but that kind of thing happens often. A lot of smd components aren't marked with values so frequently you have no idea what you should use as a replacement. Like with computer repairs, the pros themselves are going to swap things at a pcb level if they can. But go for it if you like a challenge!

If you're lucky and a SMD or minor IC fails (usually regulator/mosfet), it's easy to find and fixable for very cheap. Same if the PSU fails and not the mainboard. But yeah, both of these cases are rare in modern tv's.

I have an older, very early gen LED 1080p tv (2012-ish) at a relative's house, very well and very over engineered compared to current gen led tv's, i replaced a transistor (and speakers while at it) by myself, i also added a little radiator over the main cpu thingy as it was getting hot. 4 years later it's still holding on under heavy usage.

That's awesome.  My 40 in tv is from about then too and i replaced the power supply on it, but it uses an external one....  lol.  easy peasy fix.  HAHA.
