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. --- End quote --- 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 :-// |

We know this because we occasionally hear about people who found less-than-perfectly refurbished boards after a repair. |
