The keyboard customer says a kid peed into it, smells wonderful; strip the board and clean it, it sticks to the soldering iron, hook up a power supply set to 6V, OK, perfect fix. Two electric cooking pots that light up but don't heat (one setting doesn't work): first check whether the pot is worth fixing; when the heating element in this kind of pot dies it's generally scrap, two coils gone and can't be replaced, wouldn't last even if replaced, the aluminium poured on and hammered by hand is too loose to conduct heat, already broken; don't fix it, see if it can go for scrap. The other lights up but no steam: it sat unused for a while, the pot's dead and not worth fixing; pour the water out after every use, water left standing causes leakage; Shanghai Hongxin was big back in the day; look how corroded the pot is, from standing water, clip on the earth wire and it's a dead short, how did the breaker not trip, leakage should trip it, a miracle it unscrews at all, can be patched up to work, replace both parts, the inside needs cleaning, rinse it out with water often after use. Haier vacuum with short standby, replace the battery: take the battery out, fit domestic grade-A cells, measure 21.6V; cells perfectly fixed, strong suction, brilliant with the new cells; check charging voltage 25.6V 500mA, charging wattage 13W, 14W (half, normal), charging current normal, perfect fix. 52 comments: the most refined man on Douyin (4); dropped off a stew pot a month ago and can't find it; mirror not done in over half a month; air fryer sent in last month, no call yet (contact the repairman, he's busy and doesn't check Douyin); can a sealer be mailed in; what time do you close.
