In order to get a copy of Tetris for the NEC mini5 series of word processors, I had to buy it along with a whole word processor set from the previous owner. This LCD-based mini5SX is sleek, attractive, surprisingly heavy, and broken. Very, very broken. Let's see if we can fix up this grey beast, and dump its ROMs.
[...] Unlike some other computers in the hoard, the mini5SX was bought on Mercari, where it was being sold by the owner and not some nth-generation reseller or junkyard. This person was nice enough to explain the fault in the ad. Their word processor used to work, and they'd test it once in awhile, but the last time they took their beloved companion out (to play Tetris of course,) it wouldn't start up. There would be a dim flicker of the power light, it would extinguish, and then no response. Thus, the sale.
[...] Not knowing much about the mini5's internal structure, I decided to start by opening it up and finding the power supply. I hoped that I would find something incredibly obvious to replace, like a vented capacitor.
[...] Although I bought this machine only to get Tetris, I couldn't bear to see it in such poor condition. Now I have two Bungos, which I think we can all agree is what makes a house a home.

The manufacturers seldom care much beyond the expiration of the warranty period. Whatever component will live just long enough to get past the warranty time is also usually the cheapest one out of a set, and so to shave down the BOM cost, the cheapest, that lives just long enough, is picked.
How long, or not, that actual component lives is generally immaterial to them, just so long as it is just long enough to get past the warranty timeframe.
