Repair or Replace
mendip_discovery:
I doubt the modular pcb boards go anywhere to be repaired. I suspect it's cheaper and more reliable to just make a new board.
I know some places like to refurb stuff but that is usually mech stuff and that is often strip, clean, new seals and reassemble and test.

The issue isn't the repair itself its getting the schematic/service manual/service software and the parts. Which is all artificial limitations on 3rd party repair.

So devices have gotten more complex, have more parts, wider variety of parts, probably more proprietary, and smaller SMD parts, and yet they are "just as easy" to repair?
Yeah no.

... last night I tried the well known fading LCD segments zebra strip repair to my own Fluke 73.
My first actual repair of this type, after watching it done a fair few times on YouTube - over the years.
So, my experience was it took less than 5 minutes and there were no issues.
I've had this multimeter from new and the LCD segments were increasingly fading and going missing.
The long delay at a simple repair attempt I think was in part down to the repair/replace conflict over the zebra strips - as without the simple experience of a successful cleaning repair under your belt "the being sold a replacement new part solution" was normal.

^ Good move there!
Back in the day had to repair a Marantz Amplifier that came from 3 other repair shops & I was shocked to see the one of the Main Output Board's (single side) copper traces peeling off coz of repeated soldering. Told the owner there is no way to repair/ fix this mangled board But I had a solution.
Told him that I could copy the other output channel that was working & that's what i did. Manually tracing & measuring the distance of parts then whipping out a potion of Ferric Chloride & Varnish. Made a new amp channel & got it working with "almost" no Audible difference 8)
Patience is a virtue of those back in the day
Now only a few has it, when we bring something to be repaired, mostly will say oh we have to replace the whole PSU or Control Board or Mainboard :-//

Computer and phone manufacturers most definitely do it. We know this because we occasionally hear about people who found less-than-perfectly refurbished boards after a repair.
