Who says?
How about a display module that uses deeply embedded filament lamps for various rather important indicators on a combine harvester. Dealer claims the unit can't be repaired and has to be replaced at a cost of thousands of pounds - in a week's time.
Well, the small engineering firm I used to work for made some discoveries. It became obvious that the reason the lamps were so deeply embedded was to stop people taking them out - but that was solved with a bit of rubber hose and a vacuum pump - they were ordinary bi-pin ones, only not quite ordinary. the pins were slightly thinner than normal and slightly further apart.
We solved that problem (and the deep embed) with an LED and a resistor - also resulted in a much brighter display.
Oh and as for the 'short' working days, round these parts they harvest well into the night using high powered searchlights attached to the machines.
I wouldn't be paying - just resetting and uploading a clean copy.There are 4 of us that keep full repositories and we all work entirely via the CLI. We also keep more than one remote on different hosts.
None of us do any auto updates either - all done manually, barely any slower and much safer.
That would have been in the late 1960s when I said I had 'colour' experience, but didn't point out that it consisted of switching on and adjusting the tuner at customers' houses.
I sweated buckets for about 3 months and learned fast. Never repeated the experiment!

But on the plus side, not many 19yolds were pulling in £25/week and driving a brand new Escort Estate in those days.
No information is better than wrong information.
Rule 2: See rule 1
P.S. In another life our people made some information displays. Only when the program was running along nicely would it send a series of pulses via the parallel port (remember them). A little C/D/R/C board hanging on the display module itself set the enable line. The C/D bit was so a stuck Data High wasn't a problem.
