PSUs are definitely a specialist art firm, especially SMPS units - almost no-one makes their own.
However, that doesn't mean that you can't repair some stuff - I've repaired several flat screen TVs, either replacing backlight LED strips (replacements easily available for most TVS) and re-capping SMOS units that drive them (common problem with Samsungs and some others).
The big question is "what constitutes economic repair? i.e. how much do we value our time at.
Like most here I suspect, we hate chucking stuff out - I may have a degree in EE and have designed avionics for fighter jets, but SWMBO has me fixing all the white goods in the house - two days on the dishwasher alone! She costed that repair at GBP 100 for the new pump and pressure switch off eBay, i.e. compared with the cost oi a new Miele unit, a complete bargain. I costed it as GBP 100 PLUS two extremely rare and valuable days of my Christmas break - nearly 20% of my holiday time.
Economic? Borderline. I only do repairs on stuff for close friends and family.
