A post-80s appliance repairman in the provincial capital earns ¥480 in a day: a Hisense TV with picture but no sound, two small components replaced, ¥150; a floor washer showing E10 and not charging, all 6 original cells replaced (new cells checked on an internal resistance meter, thick nickel strip spot-welded), ¥290; an 890W health kettle, ¥10; a restaurant electric cooker rewired with 16A cable, ¥30
A first-person record of one day (a live earnings counter sits top-left). Job one, a Hisense TV: clear picture but no sound even at volume 100; checked with a ‘Da Vinci tester’, two small components found open, desoldered and replaced, power on and the long-lost sound is back — perfect repair, ¥150; the creator also invites viewers’ LCD TV questions. Job two, a floor washer that won’t charge and shows fault code E10: pull the pack and measure, two cells badly aged, so all 6 original cells are replaced; each new cell is checked on a battery tester (internal resistance meter) (ASR readings of 10.17 / 11 and so on); the ‘Kill-You 3000’ spot welder welds thick nickel strip to try the weld quality — perfect; pack fitted, anti-vibration foam stuck on, hot glue heated and applied, fixed and OK, earnings jump to 440 (+290). Job three, a health kettle: the ‘tian’erte’ (thermostat / thermal fuse) replaced, 890 watts, 4 amps, that’s right, earnings 450. Job four, a restaurant electric cooker with a broken cord end: rewiring sounds simple but is a hassle, the plastic has hardened and is hard to open; cut off the end and fit a new cable, 16A cable for 3000 watts; a touch-up solder that isn’t solid gets redone; when done it looks original, ¥30. ¥480 for the day, knock off. 469 comments, heavily divided: ¥150 for two diodes is ‘brutal’, a used TV is only ¥120 so not worth repairing; the other side: ‘you’re paying for skill, if you think it’s expensive you’re a layman’ (liked by the creator); ¥290 for 6 cells plus labor is a bit high, over ¥200 profit; someone built their own ‘Kill-You 3000’ and asks for pointers.

At these prices I bet lots of people walk away, a used TV online is 120 now, most probably won't bother repairing

Anyone calling it expensive is a total layman, you're paying for skill here, could you fix it yourself? (liked by the creator)

That first TV, ¥150 buys a perfectly good used one. Not worth repairing at all

Da Vinci, I built the 'Slay-you 3000', Master Zhang please give me some pointers.

6 cells plus labor for 290 is a bit steep

I used to do appliance repair too, but once small appliances started going for ¥9.9 with free shipping I switched trades. Question for everyone: when a small appliance at home breaks, do you still take it in for repair, or toss it and buy new

Of course skill costs more than materials, otherwise go buy the gear and fix it yourself (liked by the creator)

6 cells, minus cost, 200-plus clear profit, awesome!
