The CMMB Huibang handheld TV bought in Tmall's official mall suddenly lost the signal of all stations yesterday.

Due to poor management, CMMB is on the verge of bankruptcy. In many places, due to the lack of fund maintenance, the transmitting equipment has stopped transmitting signals one after another, and some equipment aging signals are getting more and more serious. There is no signal in many places in the center of Beijing now, and it is estimated that it will all stop soon. I heard that many second-tier cities and even provincial capitals have no signal. Call for advice and say that the equipment has been debugged. It shouldn't happen again. Unless someone injects capital. CMMB itself is backward in design and dedicated to home use, and its prospect is not optimistic. It should be that your place has stopped broadcasting.
