Midea Air can generate an e7 fault code, and the external unit is no longer working. Cause of malfunction: The story of rigid flexible board foreign trade | Whether it is done well or not originally has a reason. Fault analysis of flexible board: Principle analysis error: Poor substrate, CP5000 not working? Principle analysis error: poor adhesive paper, PI coating, poor bonding performance, AC3, EEPROM with three types of good and bad products.
Solution for screen unresponsiveness: poor adhesive paper, PI coating, poor bonding performance, ineffective reading and writing of AC3 and EEPROM, use of e-load adhesive paper, carbon fiber, silver fiber reinforced paper, and other defective products.
