och, i dunno if its worthy of a separate thread really, i'm going back 18 years (
) back when the first coloured CRT iMacs were coming out and everyone was fawning over the colour choices. I think OS 9 had just come out too, so not even in OS X days (which I've no clue about). The story I was referring to was a large (think it was 22") apple monitor (CRT) and an engineer I worked with had started stripping out it's main board, so I stopped him in his tracks, ask what the fault was (no power), and one 50p capacitor later, the monitor was going back repaired to the customer the same day, rather than waiting 6 weeks for a replacement board @£225 + VAT.
We also used to get LaCie external drives in (the print shops loved them for storage), with popped PSUs, they used to get sent back to LaCie in France @ £60 a pop and 9 month turnaround. One day I convinced the service manager to leave me a few instead of rushing them out the door, spent a day figuring out in 9 out of 10 cases, it was a high power "feeder" resistor which was underrated, and go open circuit due to heat damage. 15p for a higher power resistor, 30 mins to replace it, and customer had them back the same or next day. After that, we only ever sent back the ones where it had taken out the primary switchers, and basically destroyed the PSU.
All that was back when I was good at repairs.
