Xiangshan electronic scales EB9005L maintenance

I have the same one. I used it for a year, but it was not easy to get started at first. I changed the battery and found that the original battery still had electricity. Unplug the battery, reinstall it, and you can turn it on. After automatic shutdown, it will not be turned on again. It's not the switch. I directly shorted the switch pin on the circuit board, and the voltage was pulled to ground, so I couldn't turn it on. Then, the scale fell asleep and could not be opened any more. That cow shit chip is dead. So the pieces of cow excrement are quite inferior. Mind you, the quality of this thing is really bad. Don't get wet, or it will break faster!
