Replace CBB2 1 105J400V, and the capacitance will be attenuated! Go to the electronic city and buy a new one, one yuan each. My DDZ- 1 18 1 is such a situation that the problem is solved in one yuan.

Bear service is terrible! Despise! Taobao's official store is shameless: it is called DDZ- 1 18 1 zero maintenance. Complaining about Tmall, Tmall blindly protects its own shortcomings!
